SYNOPSIS STEAM POWER PLANT :- Introduction :- Thermal Power plants provide the major share of electrical energy ! India as well as in other countries. In steam power plants, the hart of combustion of fossil fuel (Coal, oil & gas) is utilised by the boilers to raise strem at high pressure and temperature. The steam so produces is used in driving the steam turbine or sometimes steam engines coupled to generators and thus in generating electrical energy Essential features of such power plants are boilers turbines coupled to electrical generators, condensers and large number of auziliaries. The thermal efficiency of steam power plants 6

is quite low (about 30%) and overall efficiency is about 29%. In steam power plants more than 50 percent of total heat of combustion is lost as heat rejected to the condenser.

MERITS & DEMERITES MERITS:- Fuel used cheaper, less requirement in comparison with that for hydro-plants cheaper in initial cost in comparison with other types of power plants of same capacity, cheaper in production cost in comparison with that of diesel power plants possibility of responding to rapidly changing loads without difficulty and capability of working under 25% over load continuously.

DEMERITES:-

High maintenance and operating costs, pollution of atmosphere requirement of water in huge quantity, handing of coal and disposal of ash-quite difficult, long time requirement for erection and put into action etc.

A BRIEF WRITE-UP ON THE PROJECT

The project highlight some useful points on precaution for safety from National Disaster like cyclone, in the coastal regions. The priority has been suggested for building of multipurpose/ multistoried cyclone shelter, installation of wind mills on roof of building for production of Electricity to supplement energy during cyclone, conservation and purification of rain water for drinking purpose and collection of advance information about the water level during tidal flood etc. Thus the project is primarily designed as a way out for the cyclone prone citizens of the coastal area. 7

AIM OF THE PROJECT :

Building of multipurpose cyclone shelters and spread of awareness about them in the public having the following advantages :-

a) Production of electricity by using wind mill. b) Conservation & purification of rain water to get drinking water by filtering process. c) Information about the water level of tide of the sea.

INTRODUCTION :

Odisha is a lifelong companion of natural calamities. People of Odisha in general and those of the coastal areas in particular face brunt of the calamities on a regular basis. They have to pass through unspeakable physical and mental sufferings on account of the grievous calamities. They are rendered homeless and heartless. They are left battered and suffered often paying with their lives. Among the disasters that have their foot-falls in Odisha, the cyclone are the worst to deal with on numerous occasions they have been the looters of luster fracture of faith, deformer of dreams polluters of peace of life. The super cyclone of Oct. 29‟ 1999 is a case in point that scattered unfortunately with technology at hand and keeping in view the suffering of the people and to find a satisfactory solution to the problem where cyclone centers are planned.

WHERE THE CENTERS SHOULD BE BUILT:

The location of the cyclone center is of permanent importance. Obviously, the coastal areas that bear the brunt of the cyclones should be given the priority in this regard. They should also build in other regions if they are cyclone prone.

HOW CAN THEY BE PEOPLE-FRIENDLY AND THEIR VERSATILITY?

Such cyclone shelters mining at providing multiple benefits for the people should be built at convenient location in the cyclone prone in the coastal areas with the help of modern technology, 8

they should be so built as to be scientifically in a verity of ways the ground floor of this multipurpose cyclone centers will be a safe haven for the cyclone litchis and their life stock during cyclone, At other times (when there is no cyclone), the first floor or second floor may house a school. The top floor (if it is a multistoried structure) may be used for the production of wind induce electricity (using turbines run by wind force) which may solve the problem of electricity to some extent in the locality concurred the top roof of the building may be used for the installation of equipment or machines for the preservation of solar energy which, like the wind-driven electric power, may be utilized for operating fans & TV and other electricity driven equipments, purposes and other such purposes which will bring smiles along the lips of the people simplifying their extension complexities. The wind mills may be installed on the roof of the said multipurpose building so that they can supplement the required power to run the electrical devices. The careful plan should be given for the development of more wind resistable blade of the wind mill to bear the pressure of wind during cyclone.

The preservation of the rain water for drinking and usable purpose can be given importance. The said water is to be collected through pipes to be stored in a large container installed anywhere in the building and by using power filteration process, the water recycled for multi purpose use to supplement water shortage during cyclone.

When the tide of the sea hits the dangerous sign of the measuring scale the siren of the cyclone centre rings by a conduction wire. Then the people will be alert & take precaution for the safety of their life & property by shifting to the safer place especially move to cyclone centers.

An NGO may be allowed to function in any room of the building which will look to the benefit of the local propulace. The ground floor may be allowed to house a daily market or weekly markets so that it will come to the help of the people and it can be quickly vacated during/ in the event of a cyclone.

CONCLUSION :

The multipurpose cyclone shelter / center will be blessing without any disguise. Really, it will go long way in looking to the multifarious needs of the local populace. With their problems in check, they can lend their hand in nation- building. Such a system would surely lace smiles of satisfaction along the lips of the people-particularly the local population.

Electricity from Geo-Thermal Energy

Owing to the explosion of population in India so as the world the number of vehicles, factories etc. is increasing at an increasing rate. The energy from the various traditional sources like Thermal Energy, Hydro Electricity and the Atomic Energy is unable to cater to the requirements of this growing population. So we should try to generate energy from undiscovered sources. In this context I am to hereby put forth such a project in which we can re-generate electricity from an untraditional source. The project may be named “Electricity from Geo-Thermal Energy‖.

Requirements :- i)Heat exchanger tank ii) Pump iii) Metal pipe iv) Liquid Iso-Butane v) Turbine vi) Generator vii) Condenser Preparation Procedure :-

Firstly, the water is to be lifted from a deep well measuring 400 ft to 600 ft. or from a hot spring. Then the water should be kept in a Heat Exchanger Tank. Secondly, a coiled metal pipe should be kept inside it and one end of the pipe is connected with the liquid Iso-Butane tank and the other end is to be connected with a turbine. Thirdly, the liquid Iso-Butane is lifted from the tank and is to be circulated through a metal pipe. As the boiling point of liquid Iso-Butane is much lower than the hot water of the hot spring, it collects the heat energy and converts it to vapour. When it flows in the metal pipe it accelerates the turbines and generates electricity. This vapour passing through the condenser again gets converted 14

into liquid Iso-Butane. This goes on in a cycling process and the liquid Iso-Butane never comes to an end. In this process electricity re-generated continuously without any break. Advantages :- i) There will be no deficiency in the supply of electricity as this Geo thermal energy, which is a renewable, perennial source of energy, is utilized. ii) There will be environmental pollution and causing any health hazards. iii) By establishing/ setting up this plant near a hot spring or a hot spot, the electricity can be generated continuously without any break and without any pollution. iv) Of late, coal blocks are going to be exhausted from coal mines very soon and the irregularities in the distribution of the coal blocks are vital problems for producing thermal energy. So increasing demand for energy can be fulfilled by establishing such power plants here and there everywhere. *****

INTRODUCTION :

With the increase of population in the world, shortage of potable water is becoming more noticeable. Just hundred years ago water was free and you couldn‟t imagine that some day you will pay too much money for a bottle of water. In the past few years some large bottling companies have tried to dominate the water resources of the world by purchasing natural springs and other water rights in many different countries.

Soon many people in the world can not afford to purchase fresh or drinking water. When we run out of fresh water resources, we will need to purify water for our consumption.

Distillation is the most reliable and efficient method of water purifications. All other methods including de-ionization and filtration can only remove parts of impurities and often introduce new impurities to the water. Distillation is often performed by heating water to its boiling point. At that temperature water evaporates. Vapor water is then directed to condensers where liquid water will be formed again.

Can we use solar energy to distill water? Heat energy from the sun can warm up water, but it can not bring it to the boiling point, however we have seen that water evaporates and makes wet objects dry even without heat or sunlight. Can we use the natural evaporation of water to purify polluted water? We have seen that hanging cloths under the sun will make it dry faster. Can we use the same method to evaporate and re-condense pure water ?

PURPOSE :

The purpose of this investigation is to design and construct a water distillation apparatus that can work with solar energy. We will try to employ every possible factor that can contribute to the evaporation and condensation in our design. For example we will use fan to decrease surface pressure of water by using fans which are worked by solar cell and cooling outer surface of condenser etc. and then we will compare efficiency of these ways.

EXPERIMENT DESIGN :

Introduction

Obtaining clean drinking water is a constant challenge in many countries. Often the only water available is rife with disease – causing bacteria, and must be disinfected to make it safe. 17

Conventional methods for disinfecting drinking water, including boiling and adding chlorine compounds, can be time- consuming and expensive. In some regions, it is difficult to ensure a reliable supply of chlorine, which can also give the water an unpleasant taste. In many areas, there is little fuel available for boiling water.

In this experiment we intend to make a low-cost, practical means to provide safe drinking water in rural and urban areas where needed. The key to this method lies in the ability of direct sunlight to destroy bacteria (direct sunlight can not destroy bacteria although it can make the evaporation of water faster). The treated water is expected to be suitable for drinking. Solar radiation is a form of renewable energy that is abundant and accessible in many areas in the world.

Sunlight with wavelengths of 315-400 nanometers (nm) on the ultraviolet (UV) range of the electromagnetic spectrum is most effective at destroying bacteria. Since colorless glass or plastic can transmit light in this near ultraviolet range, they are the best materials for disinfections. Visible light (400-750 nm) next in terms of efficiency, with the visible band of violet and blue light (400-490 nm) is the most useful within this range. As a result, violet, blue, and very light green- tinted glass follow colorless glass or plastic in order of suitability.

For increasing system efficiency we have some ways. For example we used fan which are worked by solar cell inside the container. First we attached fan wind to the surface of water to decrease vapor pressure and then we put one of the fan surfaces of mirror reflector for cooling glass cover. And we painted bottom of container to black color because block color absorbs solar energy. We attached glass sticks on two walls of container to collect condensed water drops from upper wall to water tank. And to make movement of drops on cover we rub oil on the bottom surface of cover.

Potential users

The system can potentially be used in small communities, refugee, camps, institutions, and in disaster situations where water supply is interrupted. And it can be used in factories for their water recycle. Waste water can be distilled from its impurities for reusing.

Experiment : water purification by solar distillation and increasing efficiency of system

Every solar water distiller has a tank of polluted water covered by a clear glass or plastic, slanted or curved such that the condensed water vapors can slide down into the distilled water storage.

PROCEDURE 18

In this design a sheet of glass will be used. This clear cover is installed in an angle to force condensed water to move to one side where it will be collected.

As sunlight warms the black bottom and sunlight is reflected by mirror which is back of system, then heat is transferred to the water, the top of the water evaporates on to the inside of the glass cover, which is tilted toward the fresh water drain.

INCREASING SYSTEM EFFICIENCY :-

We must know factors effecting vapor pressure. They are amount of surface area – the greater the surface area exposed to the surroundings the faster it will evaporate. Poor some water on the floor and put the same amount in a cup or a bowl, the water on the floor will evaporate much faster. But in our system surface area is constant because we will use same system.

Humidity – this has to do with vapor pressure. If the air is extremely humid there will already be a lot of water vapor in the air, not allowing as much of the water to evaporate. Because of this factor we try to decrease humidity in our container by using fans and cooling cover down.

TEMPERATURE OF THE SURROUNDING :

This one is simple, put some water in a cold environment and some water in a warm environment and obviously the warm one will evaporate faster. There is more energy in warm air. For our system it depends on weather of the day.

TEMPERATURE OF THE LIQUID :-

Same as above. For this case if we use less amount of water, system will warm up shortly. So it will help us about time.

WIND SPEED –

More wind blowing across the surface of the liquid means there will be constantly air with no water vapor in it right above the liquid, resulting in a faster evaporation. This is why putting a fan on a wet carpet or something of that sort will dry it out faster. For this situation we use fan of solar cell. 19

The structure of our design is like following (theoretically)

We can find most of the parts in a hardware store. Professional solar vessels are generally made of glass over formed sheet metal. But the base can be made of anything that will hold up outdoors. So that it is easy to build up. And soon it will amortize its cost. Here instead of glass we can also choose hard transparent plastic.

WATER POLLUTION MANAGEMENT

The sphere of human activities has increased manifold with advancement of civilization. In most of the cases it has led to the deterioration and pollution of a very important and priceless natural resource like water. The gegredation of quality of usable water has created a scenario of threat and 21

challenge for the future generations. Waste water generated from different agricultural, industrial and domestic sources pollute and contaminate various water bodies to a large extent being the causative factor of deadly water borne diseases. That is why a proper treatment procedure of the contaminated water becomes highly essential before it is finally drained out. This is possible by the application of modern technological procedures into the whole system. The project under discussion is a brief analytical description of one among them.

The integrated action of the following major components funcutionalises the project.

1. Grinding Mechanism 2. Settling Chambers(Primary treatment) 3. Anaerobic Degredation (Secondary treatment) 4. Active Sludge Recycling 5. Aerobic Degredation 6. Integrated Boiling and Condensation

There are three major stages for the treatment of contaminated water.

(A)Primary Treatment:

First of all the sludge water is made to pass through a grinding mechanism. Then it passes through several settling chambers where it gets neutralized by the action of lime.

-1- (B)Secondary Treatment: The neutralized water generated out of primary treatment contains several pathogens along with huge amount of organic matter. It is then sent to “USAB”(Up-flow Anaerobic Sludge Blanket) where the inherent bio-degradables get simplified by the action of an anaerobic bacteria. This process makes water odourless with the evolution of Methane to be used elsewhere. The rate of pollution of the sludge water is decreased by 85% through secondary treatment. Subsequently this treated water is made to pass through an Aeration tank where an aerobic bacteria simplifies the organic wastes. Therefore it is known as “organic treatment”.

(C) Tertiary Treatment :

The water generated out of secondary treatment is not potable as it contains various pathogens. A tertiary treatment is required for the complete annihilation of these pathogens along with the treatment of the remainant organic and inorganic wastes. This is achieved through processes like Chlorination, Evaporation, Condensation etc.

Other essential steps for prevention of water pollution:

22

Waste food materials, rotten vegetables, plastic wastes etc. should not be thrown into an open drain. Industrial wastes both solid and liquid must be sent to Biogas plant for the purpose of energy generation. Use of absorbants and saw dust at the places of oil leakage must be encour.

DEFINITION & AIM OF THE PROJECT:- A solar cell is basically an eco-friendly a-p-n junction which generates emf. When solar radiation falls on the junction.

STRUCTURE :- A P-Sc wafer of about 300llm over which a thin layer (-0.3um) of n-Sc is grown by diffusion process. The other side of P-Sc is coated with a metal (back contact). On the top of n-Si is grown by diffusion process the other side of P-Si is coated with a metal (Back contact). On the top of n-0Si layer, metal finger electrode (or metallic grid) is deposited which occupies only < 15% of the cell area.

FUNCTION:- The generation of emf by a solar cell, when light falls on it, is due to the following three basic processes: generation, separation and collection –

(1) Generation of e-h pairs due to light close to the junction.

(2) Separation of electrons and holes due to electric field of the depletion region. 25

(3) The electrons reaching the n-side on the front make it negative and holes reaching p-side by the back contact make it positive giving rise to photo voltage.

UTILITY:- Semi Conductors with band gap close to 1.5ev are ideal materials for solar cell fabrication. Semiconductors when doped with trivalent impurity or pentavalent impurity forming P-type and n-type in the latter with a band gap close to 1.5ev are ideal materials for solar cell fabrication.

Objective: Energy generation from renewable sources &conservation of non-renewable sources &provide better environment &solve energy crisis

Procedure:

Bio-Hydrogen:-In biological Hydrogen Factory , by limiting the Oxygen & Sulphur supply to the abundantly grown algae (Chlorella, Chlamydomonas)& Bacteria, we can change their metabolic process, so that instead of liberating Oxygen, they will liberate Hydrogen in photosynthesis;.

By using Chloroplast and Hydrogenase enzyme derived from above algae & Bacteria, we can also get Bio-Hydrogen which is a pollution free fuel. 30

Bio-Ethanol:-By fermentation of Carbohydrate wastes, Cellulose, Aquatic weeds, we can get Ethanol which is used as fuel.

Bio Methane:-By methanogenesis of Municipal wastes in landfill site, Methane gas is produced; which is used as fuel in cooking

Bio-Diesel: - From non-edible oil-rich seeds like Jatropha, Karanja, Neem, Mahua we can get Bio- diesel by esterification method which is used as fuel in vehicle.

Energy Plantation: - Some plants like Eucalyptus, Melia, Casurina have rapid growth & more caloric value which can be planted and used directly as fuel..

Mathematical Representation of Farmer‘s Fertilizer

Introduction :

The high yield of the crop mainly depends upon the fertility of the soil. Fertilizer is the basic amenity for the soil‟s ferlity but it is a matter of regreat that due to the lack of sufficient knowledge in Science and technology in the field of preparation of home made fertilizer, the percentage of nutrients in the fertilizer they generally used, are rare As result, less yield in the crop, as they imagine. 37

For this to demonstrate the topic “ Science and technology- a chellange of the life”. I present a mathematical project by using graph and mathematical derivation. i.e. “Mathematical Representation of Farmer‟s Fertilizer”.

Objectives :

1. To increase in the production of the crop by improvising the quality of the primary and basic nutrents in bio fertilizer. 2. The quality of the bio fortiliser is directly proportional to the yield in the crop. Symbolically quality of fortiliser crop production. Materials required :

1. Plywood – six square foot 2. Graph paper – four piece 3. Thin wood plate 4. Bearings – one piece 5. Plastic tube – five foot 6. Copper wire – five metre 7. Blade – one piece 8. Led ball – thirty piece 38

Construction of Project :

A – Baseplate – A bearing is connected in the middle of the plane surface of a cylindrical wood. A piece of wood measuring 1” length is pasted in the middle of the bearings. Baseplate is made by pasting wood plate measuring 1‟1”x1‟1” parrellaly and connected to the bearing through a nail. To give the baseplate, the shape of a cube four pieces of plywood 1‟x1‟, are fixed a long the four sides of the baseplate. Graph paper are coated along the four surface area of the cube. As the baseplate is connected by a bearing, the four sides contains graphical picture is demonstrated easily.

B- Construction of the graphical picture of the first surface Two circles made of plastics are prepared to demonstrate he actul % of N.P.K. in fresh cowdung and the % of N.P.K. after loss due to evaporation, filtration, and absorption through circular graph. The first circle measuring 3600 is divided into three angles measuring 1440, 720 and 1440 to demonstret the actual % N.P.K. in fresh cowdung. The second circle measuring 3600 is divided into three angles measuring 500, 180 and 500 to demonstrated the % of rest Nitrogen after the loss of Nitrogen due to evaporation by the sun, the % of rest phosphorous after the loss of phosphorous due to filtration by the water, the % of rest potassium after the loss of potassium due to absorption by the soil. Both the circles are covered by white semipermable polithene. Led bulb of multi colour ie-green, red and yellow connected with three switch S1, S2, S3 made of shaving blade, are fixed in both these circle to demonstrate the actual % of N.P.K.

C-Working of the first surface area –

The green led bulb situated in nitrogen cell of both fresh cowdung and general manure, gives light when S1 switch is on. Similarly when S2 switch is on the red bulb situated in phosphorous cell of both the circle gives light. Again when switch S1 is on the yellow LED bulb of potassium cell of both the circles gives light.

Mathematical analysis of circular graph of first surface area :-

1- Nitrogen present in fresh cowdung is 0.4% It losses 66% of Nitrogen due to evaporation by sun.

It means 66% of 0.4= 0.264% loss

Rest Nitrogen = 0.4-0.264 = 0.136% or 0.14%

2- Phospherous present in fresh cowdung is 0.2% It losses 75% of phosphorous due to dilution with rain water

It means 75% of 0.2 = 0.15% loss 43

Rest phosphorous = 0.2-0.15 = 0.05%

3- Pottasium present in fresh cowdung is 0.4% It losses 66% of potassium due to absorption by the soil

It means 66% of 0.4= 0.264% loss

Rest potassium = 0.4-0.264= 0.136% or 0.14%

It is clear that, due to the lack of knowledge in science and technology a farmer get the cowdung having very low value of N.P.K. in it i.e N=0.14% P= 0.05%, K =0.14%. It does not meet the basic requirement of the crop. That‟s why, a Farmer depend highly upon chemical fertilizer.

B- Construction of the graph of second surface area.

Two axis X and Y are drawn on the graph paper to represent the ratio of crop yield due to chemical fertilizer and the percentage of nutrients in the crop. X axis shows the availability of nutrients in crop while Y axis shows the percentage of the crop productions. Five cells re-constructed with the a help of six piece of thin woodplate by fixing.

Vertically to the X axis

These are

(i) Shortage of chemical fertilizer (ii) Negligible shortage of chemical fertilizer (iii) Sufficient use of chemical fertilizer (iv) Too sufficient use of chemical fertilizer (v) Poisonous state

Every cell is connected with a led bulb which are connected with five switch named S1,S2,S3,S4,S5. These five switch S1,S2,S3,S4,S5 are covered with yellow, green, red, green and yellow colour respectively.

Working of the second surface area :-

When switch S1 is on the led bulb gives light which shows the shortage of chemical fertilizer. When switch S2 is on the led bulb gives light which shows the negligible shortage of chemical fertilizer. When witch S3 is on is the led bulb gives light which shows the sufficient use of chemical fertilizer when switch S4 is on the led bulb gives light which shows the too sufficient use of chemical fertilizer. When switch S5 is on the led bulb gives light which shows the poisionus state.

44

Mathematical analysis of second surface area :-

There is a limit to use chemical fertilizer in the field which is termed as critical limit. By using chemical fertilizer blindly in certain cases, a plant cell get less as compared to critical limit and in certain cases a plant cell get more and it reaches the poisionus state. Hence the growth of the crop and the production also decreases highly which can be easily diagonised with the help of S.Singh‟s graphical figure which demonstrate how nutrition management in a crop affects the crop production.

When there is a shortage of nutrient in crop the production decreases to 55%. When there is a negligible shortage of nutrient crop the production decreases to 60% -80%. When there is sufficient nutrient in crop the production is in between 80% to 100%. When there is too sufficient nutrient in crop the production again reduced to 60%. When it is in poisionus state the crop productions decreases highly and in more cases the crop deceased also.

Construction of third surface area :-

X axis represent several types of biofertiliser i.e. fresh cowdoung, decomposed cowdung, trichodormaviridi, pencilium, aspergilus. Y axis represents the percentage of carbon, Nitrogen and the ratio of carbon and Nitrogen. To demonstrate the actual percentage of C,N, and C:N of every bio fertilizer represent in X axis are connected with red, green and yellow led bulb respectively. There exists eight number of switch named S1,S2,S3,S4,S5,S6,S7,S8.

Working of third surface area :-

S1 switch represents the % of C,C:N, and N in fresh cowdung

S2 switch represents the % of C,C:N, and N in decomposed cowdung

S3 switch represents the % of C,C:N, and N in Trichodormaviridy

S4 switch represents the % of C,C:N, and N in Pencilium culture

S5 switch represents the % of C,C:N, and N in Aspergilus culture

Again the red, green and yellow led bulb are connected with S6,S7 and S8 respectively Mathematical analysis of third surface are.

All the bactria which decomposes the cellulose present in the cowdung, culture with cowdung, enhances the process of decomposition and hance in creases the nutritional value of the cowdung. The ratio of carbon and nitrogen gradually reduces through bactria culture.

45

Position of carbon and Nitrogen, C:N in several biofertiliser

Bioproduct Carbon Nitrogen C:N Scientific Conclusion fresh Cowdung 47.76 1.45 32.93 Ranjan Kumar Tripathy

when the ratio of C:N is greater then 30 the Nitrogen is constant in the soil and hance in primary stage crop don‟t take Nitrogen from the soil.

De-composed 42.10 2.07 20.34 moon and Associates, 1972 cowdung (After 3 month) When the ratio of C:N is less then 30 it reduces the Nitrogen.

Bactria culture after 3 months 40.10 2.3 17.43 When the ratio of C:N is less then 15, 1- Tricho- mineral Nitrogen is produced in the dormaviridi 38.71 2.61 14.83 soil during the process of 2- Pencilium 3- Asperjilus decomposition and hence easily 38.58 2.70 14.28 acceptable for crop.

Having a clear and vivid observation, it is generally obvious that by bactria culture the % of carbon decreases gradually on the other hand the % of Nitrogen in creases gradually. As a result a decreases in the ratio of C:N. It is clear that by bactria culture the % of nitrogen is increasing from 1.45% to 2.70%.

Construction of the histogram of fourth surface area :-

The fourth surface area which consist of two woodplate which is named as X axis and Y axis. X axis represents the % of N.P.K. in general manure, fresh cowdung, cow-dung+ urine, cowdung + urine + bonemeals, cowdung + urine + bonemeals + bactria culture separately. To demonstrate value of N.P.K. there cells are constructed with the wood-plate. Green, red and yellow led bulb are connected to demonstrate N.P.K. respectively.

All the multicolour led bulbs are connected with S1,S2,S3,S4 and S5 switch made of shaving blade.

Working of the fourth surface area :-

S1 switch represent the value of N.P.K. in general manure

S2 switch represent the value of N.P.K. in fresh cowdung 46

S3 switch represent the value of N.P.K in cowdung + urine

S4 switch represent the value of N.P.K. in cowdung + urine + bonemeals

S5 switch represent the value of N.P.K. in cowdung + urine + bonemeals + bactria

Mathematical analysis of fourth surface area :-

Lack of sufficient knowledge in science and technology, a farmer gets the general manure of low quality having N=0.14%, P = 0.05%, K = 0.14%. The first histogram describes this above fact.

On the other hand, with the help of science and technology, one can increases the % of N.P.K. in biofertiliser. It‟s mathematical analysis is clearly seen in the histogram.

Mathematical calculation of profit and loss :-

How much a farmer having five cows get benefit while preparing biofertilise with science and technology? How much he will get more as compared to generamanure.

Solution :-

1- In general method - The quality of cowdoung available from a cow daily = 6 kg 48

Quality of straw and cowshed wortage = 3 kg

Total quality of decomposable material 6kg + 3kg = 9 kg

Deing the process of decomposition loss in weight of material = 5 kg

So quality of general manure available from cow daily 9kg – 5kg = 4 kg

Quality of manure available from 1 cow in 1 day = 4 kg

Quality of manure available from 5 cow in 1 day = 4x5=20kg

Quality of manure available from 5 cow in 365 day

= 20x365 = 7300kg = 73quintal

If one saids 1kg manure in one rupeas then , 7300kg manure 1x7300=7300 rupeas.

2- With science and technology – The quality of cowdoung available daily = 6 kg

The quality of urine available daily = 6 lt.

The quality of straw and cowshed westage = 3 kg

Total decomposable matrials = 6kg +6 lt +3 kg = 15 kg

Decomposable loss in straw and cowshed westage is 5kg.

Decomposible loss in urine westage is 5 kg.

So total decompoisition loss in 5kg+5kg = 10 kg.

So the quality of general manure available from a cow is 15-10=5 kg

So the quality of general manure available from 5 cow is 5x5= 25 kg

So the quality of general manure available from 5 cow is 365 days =

5x5x365 = 9125 kg = 91 quintal 25 kg

The quality of bio products is 11 times better as compaired to general manures so the rate of the bio product increases 11 times from general manure.

So if the rate of general manure one rupees per 1kg the rate of biofertiliser should the 11 rupees per 1 kg. 49

So 91 quantal 25 kg costs 9125x11 = 100375 rupees.

By applying science and technology in the formation of biofertiliser, a farmer gets rupees 1,00,375 from 5 cows.

Advantages :-

1- Farmer‟s can calculate how and how much nutrients will loss due to the lack of knowledge in science and technology. 2- Farmer‟s can know about the loss in crop production due to chemical fertilizer by analyzing the position and % of Nutrients from graphical figures. 3- Farmer‟s can calculate easily the quality of biofertiliser by mixing cowdoung, Urine, Bonemeals and decomposing bactria throw mathematical table and histogram. 4- Farmer‟s can show their interest to use biofertiliser by understanding the fact that the quality of general manure is directly proportional to the crop production. 5- In a recognized process of paddy cropping 50 bushes exist in 1 square metres space for high yield paddy and 25 bushes exist in 1 square metres for hybrid seeds. Number of effective rice tiller x 3 = numbers of bags (75kg) of paddy per acre.

Remarks :-

1- Farmer‟s can be self sufficient by enhancing the quality of generalmanure. It helps in the crop productions of our country. Reference book :-

We will see the deflection of electric current in the LED bulb. While proved that electric is produced. Usefulness 1. In this process if a large number of dynamo be activated, then it will possible to produce much more electricity. 2. Any loss or damage either of the road or of vehicle will not be possible by adopting this process of electric production. Rather the drivers can control the vehicles due to the presence of speed breaker. 3. We can preserve bio fossil fuels for our next generation by adopting this process of electricity production. 4. There will be no bad impact often the environment if we produce electricity in this process. 5. By using this process we can also lift water from the soil and can deliver through pipes.

A Brief Write – Up on the Project

The NASA (National Academic of science (NAS) defines that the temperature of the world increase 1 F or 0.6 Celsius within 100 years . Rather this rate of rising of temperature is effective during this twenty years .

If the rate of rising of Carbon Dioxide (CO2 ) increases in this rate ,the temperature of universe will increase from 1.50 Celsius to 4.5 0 Celsius till coming 2100 century .

Cause of rising the Co2 (Carbon Dioxide ) 1. It causes for deforestation ,increasing population and speed development of industry . 2. Along with maintenance of day to day function of life ,i.e : using of LPG ,CNG construction of urbanization and industrialization ,mines is mostly responsible for deforestation . th The safety point of carbon dioxide (co2) is 350 PPM from the middle of the 20 century the increasing of global warming is caused by C.F.C ,green house gas the density of CO2 etc.

It is known from the various point of experiment that total 2896 crore ton CO2 extracting from total industry of universe and mixed it in the atmosphere . If it continues in this m anner the earth along with biomass will be destructed too . 55

Result of global warming :- Due to global warming melting of snow in polar area ,the increasing of depression of ocean and the sea level area along with island will be seriously effected . To balance the carbon dioxide in nature is main object of the project that is ROBOT TREES . ROBOT TREE :-

This ROBOT TREE (whose leaf is not green ) acts like a green tree to free from CO2 in atmosphere .The small ROBOT TREE made by scientist observes CO2 in 1000 times more in proportion than green tree/natural tree from atmosphere .If we can plant 2.5 lakh ROBOT TREE in the earth it will properly balance the CO2 in nature and check the population in the earth and people will able to maintain healthy life . Conclusion :- It is known from this experiment that if we can able to plant 2.5 lakh of ROBOT TREE in world then the atmosphere will be purify instated of pollution and we the people will maintain healthy life .

A BRIEF WRITE-UP ON THE PROJECT

CONSERVATION OF ELECTRIC ENERGY Introduction :-

This project is meant for conservation of electric energy. Due to our careless & ignorance we consume more power than we actually need.

Aim of the Project :-

The street lights that we use in township & industrial belt are generally glorious sodium vapour light which need more current than other usual light. Besides due to our careless sometimes such lights glows in daytime resulting wastage of energy.

Preparation :-

In order to check the above cited two points if we replace sodium vapour light by C.F.L. bulbs less energy will be consumed. Light flame Nos. of 4 C.F.L bulb set each having power 20 watts needs only 960 wattshr (0.96 unit) whereas same light flame of sodium vapour light needs 3000 watthr (3 units) current.

Applying the above principles this project is constructed for exhibition. But with instrument of adequate magnitude and proper efficiency we can it in our day to day life especially in townships and industrial areas.

Besides if LDR kit will be used replacing switch it will automatically glows at night and off in day time which reduce wastage of electricity due to carelessness of human beings.

A BRIEF WRITE-UP ON THE PROJECT

Introduction :- The project is designed to develop an automatic irrigation system which switches the pump motor ON/OFF on sensing the moisture content of the soil. In the field of agriculture, use of proper method of irrigation is important. The advantage of using this method is to reduce human intervention and still ensure proper irrigation.

Design Principle :- The project uses a relay to On/ Off the motor, which is designed to receive the input signal of varying moisture condition of the soil through the sensing arrangement. This is achieved by using as op-amp as comparator which acts as interface between the sensing arrangement and the controller. Once the controller receives this signal, it generates an output that drives a relay for operating the water pump. The sensing arrangement is made by using a thermistor inserted into the field at a distance. According the temp of the soil the thermistor gives a voltage. This voltage is compared with a voltage comparator. The project is designed to operate a pump for automatic irrigation. It comprises of moisture sensing arrangement interfaced to an op-amp configured as a comparator. So whenever moisture in the soil reduces, it turns the water pump On. This results in increase of the moisture content which in turn switches OFF the motor. The concept in future can be enhanced by integrating GSM technology such that whenever the water pump switches ON/OFF, an SMS is delivered to the concerned person regarding the status of the pump. We can also control the pump through SMS.

LINEAR PROGRAMMING

Introduction:

Programming means systematic planning of taking decisions. Linear Programming helps us in making the best use of limited available resources to get the desired results of getting maximum product or to minimize the cost of production. Linear means indicating that all relationships involved in a particular problem are of one degree and they can be represented by straight lines.

The Founder of the idea of linear Programming is a Russian Mathematician L.V.Kantorovich, in 1947 Georage B. Dantzing developed a Superior technique for the purpose of scheduling highly complex procurement activates of U.S Air Force. Electronic Computers did a lot to the growth of linear Programming to solve many problems of business and industry.

RATIONALE BEHIND THE EXHIBIT 62

The need of linear Programming Techniques arose due to the limited resources ( Men, Material, Machines etc. ) at our disposal and hence certain constraints ( demand, Production processes and equipments, storage capacity etc. ) have to be applied in almost human activity.

MATERIAL REQUIRTED FOR THE MODEL

Plywood, thermocol, chart paper, toys ( trucks, cars, trees and blocks ) fevicol, cutter, cello tape, sketch-pens, paint.

METHOD TO SOLVE L.P.P

1. Graphical Method 2. Simple Method

Graphical method will be restricted to the graphical optimization of the objective function of only two variables. If the number of decision variables is more than two, Simplex Method can be applied.

TECHNIQUE / WORKING RULE

1. Identity the decision variables in the problem.

( Decision variables are those qualities whose values are to be determined )

2. Identity the objective function ( function to be optimized ) and express it as a linear function of the decision variables ) 3. Identity the set of constraints, stated in terms of decision variables and express them as linear in equation or equations as the case may be.

APPLICATIONS:-

1. MANUFACTURING PROBLEMS:-

We determine the number of different units produced and sold by a firm when each product requires a fixed man power, machine hour, labour hours per unit, warehouse etc. to make maximum products:

2. DIET PROBLEMS:-

Amount of nutrients in a diet to minimize the cost by giving importance to each constituent nutrient.

3. INVESTMENT PROBLEMS:-

The See saw flat has been connected with two syringe. If pressure is given in one syringe the other syringe has the power to get upwards. For that See- saw mechanism extrimend has been connected with syring plunger. A pipe has been connected with the end point. The non returning valve has been connected with pipe which has been connected with water resources. 9) Non returning valve has been arranged in such a way that it‟s upper side has been attached with a knob. The top point of the knob has been attached with the side of the spring. On the other hand an iron knob has been attached near to the spring. While giving pressure to the knob it immediately passes pressure to spring and makes it compressed. As a result there appears a vacume in the inner side. Water pushes from the water resources and comes to the vacume. The iron knob having pressed comes to the spring through this way. More over having pressed from the spring the iron bulb obstruct to the pipe. So the water getting pressure becomes upward that never comes downward. In this way two syringe with non return valve having connected with water resources. It pressure is inserted in one syringe the 66

other syringe goes upwards and sent water to the resorver. This activities are operated frequently such that water gets filled in the reserve tank. 10) The device is based upon the principle of liver, pressure and volume which has been derived from the principle of Boyl‟s low.

A Brief Write – Up on the Project AIM OF THE PROJECT • To save power from wastage through proper management of street lights applying ‗Analog Time Switch‘. • To save power at flyover bridges,highways and highway bridges by applying the latest sensor technology. • PROCEDURE • 1- A rectangular piece of thermocol has been taken.Some small pieces of thermocol have been used as light-posts.These light-posts have been fixed parallel along the middle of the road.Some LED(Light Emitting Diode) bulbs have been taken.They have been fixed at the end of the light-posts.The bulbs have been connected with three pieces of wire.All bulbs have been connected with the resistants in series to control and supply the current as much they require.Very thin conductor strips have been set in cross-section 72

manner one above the other keeping minute gap. Now the conductor strips have been connected with wires.Two batteries have been taken and the wires conneced with LED lights, the conductor strips and the switch have been connected with these batteries. Now all the wires have been joined to form a complete circuit . • 2 - The street lights have been connected with the Analog Time Switch.The time has been set with the time switch . There are 96 miniature breakers . Each breaker supports 15 minutes. The time is set according to the need. For example, we want to keep the light ON at 6p.m. and OFF the same at 6 a.m. So, here we need to lift back 48 miniature breakers which covers 12 hours. The street lights will be automatically OFF after 12 hours. • THEORY • The towns and cities have become the soul of our trade, transaction, education, health service centres, cultural units and administrative points. Almost various activities continue up to mid-night. Always we see the rustling and bustling of people and vehicles. Hence , the use of street lights are very very essential for incorporating business, trade, production, purchase, sale ; conducting various social , political and cultural activities. The most important thing is to maintain law and order, restrict anti- social activities and maintain road safety. The arrangements of streetlights is a civic amenity for the city and town people . But I do express my horror relating the management of street lights at various sites. • Very often , we see that street lights remain ‗ON‘till 10 a.m. We feel shame to remind the poster advertisement-‘SAVE ENERGY- ENRICH LIFE‘. So, I put forth my views through this project to use ‗Automatic Analog Time Switch‘ to manage the street lights.This can help to ‗ON‘ the light at the approach of evening and get ‗OFF‘ in the morning.Through this technique the lights can be used reasonably in towns, cities, market places, etc. • CONCLUSION • Thus, there is no need of manual operation to OFF and ON the lights. This will continue for many days and can save power from wastage. •

A Brief write- up on the Project

India is rich in agriculture. Mainly farmers are the back bone of agriculture. But financially most of the Indian farmers are poor. They cannot afford more money in purchasing costly implements for agriculture. To overcome their problems up to some extent, I have made this device which is of very low cost & can be handled easily. This device consists of two wastage polythene water bottle and a bicycle pump. Two bottles are fixed on a ply board. Out of two bottle one contains pressurized air and the other bottle contains pesticide solution upward. As a result the solution comes out of the bottle through a nozzle with great force and spreads over the diseased plants uniformly. Hence, I think my device can be a noble gift for farmer brothers.

INTRODUCTION:

Water and electricity are precious and a bare necessity for the society. Its loss will surely push the modern civilization back to primitive eras. In my project I have used a piston with flush to save water loss in the latrine and used the ―Microbial Fuel Cell Technology‖ to produce Hydrogen gas for automobile fuel and electricity from the sewage tank.

SCIENTIFIC PRINCIPLE:

The water pressure inside P-trap is shared by the piston to decrease the water use.

Microbial fuel cell helps in Bio-electrolysis of sewage water producing electrons and H2- gas. H2O H⁺+OHˉ

BENEFITS:

1. Low cost and water efficient latrine will inspire many people to use in areas of water scarcity. 2. Each user can produce fuel and electricity for their own use or to earn money by selling to the society. 3. It may solve the problem of water scarcity and energy crisis in rural belts to some extent.

APPLICATION: 1. This can be used in trains and aeroplanes to use less water. 2. This project can be applied for refining industrial waste. 3. This method may be applied to the treatment of domestic waste water of the village by adding Acetate and Butyrate or culturing cyanobacteria.

Water is life.It is a precious natural resource which is necessary for future life.But it is a matter of great regret that we are misutilising & polluting it.Due to wastage of million litres of water we face water scarcity in summer.In our state there are nearly 12000 water servicing stations for two & four wheeler vehicles.Each day a lot of water is used there & it gets polluted and goes as waste.

So if we do not think about the conservation and recycling of such water it will definitely lead to future water crisis.

INSTRUMENTS:

Plastic Tray

Toy car

Plastic tanks(2)

Pipe 77

Blue green algae

Azolla

Fine sand,charcoal,gravel,coconut fiber

Four chambered filtration bed

Sprinkler,nozzle,pipe

CONSTRUCTION PROCEDURE:

A model of water servicing station has been constructed on the large plastic tray.The polluted water after water servicing comes to this tray.The polluted water contains large molecuies of oil,greese & small particles of mud.Then the polluted water enters the second tank containing azolla & blue green algae.After passing through this tank water goes through the four chambered filtration bed made of tin.The four chambers contain gravel,charcoal,coconut fiber & fine sand one after another.When water comes out of the filtration bed to the third tank it becomes reusable for another water servicing.

SCIENTIFIC PRINCIPLE:

Azolla & blue green algae release a lot of oxygen to the polluted water to eradicate its bad odour and some metal impurities are also separated in this stage.Then the water passes through the four chambers of filtration bed and the gravel,charcoal,coconut fiber,fine sand separate the oily residue,mud & other impurities from water.

UTILITY:

The principle adopted in this project model ensures water conservation and it also controls the harmful effects caused due to the passage of this polluted water to water sources and cultivable lands.

CONCLUSION:

On the basis of this project we can control the vast water wastage and pollution in water servicing stations.This model rekindles a ray of hope in resolving the future water crisis.

A BRIEF WRIT-UP ON THE PROJECT Now questions arises Hazard of Energy is contradiction with conservation of energy. Conversation of energy states that the total energy in the universe is fixed – “ Energy neither created nor destroyed”. It means that energy can only change from one form to other. Hazard of energy means the deficiency of the source of energy that is fossil fuel. In the circumstances of Hard of energy I have highlighted some important application of solar energy in my project.

I have used the block coloured tin container as a water chamber which is filled with water. A handmade immersion heater (Two blades are binded with a wooden plate) is immersed inside the water. Two blades are connected with the two terminal of two wires and other electrode are connected with the solar cell which is connected with a storage Battery. Making closed the water chamber a bend pipe (G.I Pipe) is introduced at the top of the chamber and the other end is introduced in side a vapour collected container which is present inside a container that circulated cold water, A turbine is also connected at one end of the bend tube where the water vapour is hitted the turbine that it generated electricity. The electricity is collected by a step up Transformer and can be transmitted for various usages.

Whenever sunlight falls on the solar cell it is converted the solar energy to electrical energy and storage in the cell. When the immersion heater is connected with the two electrodes of Solar Battery getting the electrical energy the blades are heated inside the water and water vapour is produced and that water vapour is passing inside the bend tube and heated the turbine. The turbine is turned over in a magnetic field and electricity is generated and that electricity is collected by a step up Transformer and then transmitted by transmission wire for various usages. The returning water vapour introduced inside the water vapour container by an air blower. That water vapour is liquefied with contact of cold water. We collect the condensed water as distilled water. For more solar energy concave reflectors are used. They reflect solar energy towards the black colour container. The joint effect of reflectors and immersion heater water is evaporated quickly.

A BRIEF WRITE-UP ON THE PROJECT

CONSERVATION OF ELECTRIC ENERGY Introduction :-

This project is meant for conservation of electric energy. Due to our careless & ignorance we consume more power than we actually need.

Aim of the Project :-

The street lights that we use in township & industrial belt are generally glorious sodium vapour light which need more current than other usual light. Besides due to our careless sometimes such lights glows in daytime resulting wastage of energy.

Preparation :-

In order to check the above cited two points if we replace sodium vapour light by C.F.L. bulbs less energy will be consumed. Light flame Nos. of 4 C.F.L bulb set each having power 20 watts needs only 960 wattshr (0.96 unit) whereas same light flame of sodium vapour light needs 3000 watthr (3 units) current.

Applying the above principles this project is constructed for exhibition. But with instrument of adequate magnitude and proper efficiency we can it in our day to day life especially in townships and industrial areas.

Besides if LDR kit will be used replacing switch it will automatically glows at night and off in day time which reduce wastage of electricity due to carelessness of human beings.

POCKET PUMP AND BIKE STEP-IN AIM OF THE PROJECT :- Using this project one can avoid difficulties in the field conveyance.

OBJECTIVE : (i) Utilization from waste product. (ii) To provide safety measures for cycle/ motor cycle parts. (iii) Conveyance can remain available at low cost. (iv) To remain free from physical and mental pressure while traveling. INTRODUCTION : While traveling on bike sometimes the tube gets punctured, we are required move to a repairing mechanic pushing the vehicle forwarded which pains us a lot. It creates a lot of trouble on the part of women. In addition to it the tube gets spoiled. Hence this simple method with slightest skill can solve the problem easily. The whole process is divided into two steps. Step-I POCKET PUMP Required apparatus: i) Bulb and pipe of B.P Check-up machine ii) Nozzle – 1Pc. Sometimes the bulb and pipe from B.P check-up machine becomes waste materials after long use by the doctors when the machine ceases. At that time the bulb and pipe can be collected and attached to a nozzle this can be made into a form of pocket pump. With the help of this pocket pump we can provide air pressure into punctured tube. Thus this method can help us to move the bike forward easily and unhurt. In this way we can rich to the repairing mechanic.

Step-II BIKE STEP-IN EXPECTED PROBLEMS:  Sometimes the tube gets a bigger leak with iron nails and the whole wheel remains empty. Thus the tube gets spoiled, while pushing forward without pressure.  In some other cases the iron nail creates many pores/leaks whiles gets strikes on the roads. Thus whole tube gets spoiled.  Some times when the ball bearing gets cracked, the wheel does not move at all. So the bike is felt difficult to carry forward. PROBLEM SOLVING To save the puncture tube in wheel this method helps us a lot. We put the bike step-in under the punctured wheel. Now the bike is ready to be moved forward to reach to the repairing place without any harm to the punctured tube.

WRITE-UP OF EXHIBIT ―Solid Waste Treatment: Incineration Vrs. PlasmaGasification‖ To be DISPLAYED IN THE 3rd. Inspiration Award Science (NLEPC-013) Exhibition- 2013-14

Student ABHIJIT MISHRA Ex- student:- NEW RAMPELLA HIGH SCHOOL, AT/P.O.- RENGALI, DIST.- SAMBALPUR, ODISHA. Pin:- 768 212 INTRODUCTION Rapid urbanisation/ industrialisation has caused generation of high volume of Solid Waste. It’s disposal is a major concern now days as there are shortage of land for landfill and its adverse effect in the environment. Incineration is being used as an effective method for treatment Solid Waste. Incinerators are being equipped with various pollution control devices. Despite that Incineration system poses serious environmental hazards. It uses to contribute significant amount of dioxins & furans besides nitrogen and sulphur oxide gases in its flue gases. So there is need to search alternatives. Gasification may be the perfect alternative. There are various methods for Gasification. For treatment of Solid Waste Plasma Gasification System considered as appropriate.

RATIONALE BEHIND PREPARATION OF THE EXHIBIT This project/ exhibit explain the process and the advantages of gasification/ plasma gasification. It is a comparative study to persuade adoption of Plasma Gasification for treatment of Solid Waste. SCIENTIFIC PRINCIPLES RELATED TO THE PROJECT 94

Gasification is a process to convert organic or fossil based carbonaceous materials into their simplest molecules - carbon monoxide, hydrogen and methane forming synthesis gas/ syngas. This is achieved by reacting the material at high temperatures (>700 °C), without combustion, with a controlled amount of oxygen and/or steam. The resulting gas mixture is called syngas (from synthesis gas or synthetic gas) or producer gas and is itself a fuel. As gasification process breaks these materials down to the molecular level, so impurities like nitrogen, sulphur, and mercury can easily be removed and sold as valuable industrial commodities. There are various methods for Gasification. For treatment of Solid Waste Plasma Gasification System considered as appropriate. In a plasma gasifier high temperatures are being achieved with plasma torch. A torch in which the carrier gas (oxygen, nitrogen, argon, helium, air, hydrogen) are being passed through an electric arc (Arc formed between Cathode and Anode). The Gas is being covert into Plasma and it produces a high temperature plasma flame having high velocity. Lightening is the example of plasma flame created in natural environment. When used in a gasification plant, plasma torches generate this intense heat, which initiates and supplements the gasification reactions. The rate of those reactions can be increased making gasification more efficient. Inside the Gasifier, the hot flame from the plasma torch contact the feedstock, such as municipal solid waste, auto shredder wastes, medical waste, biomass or hazardous waste, heating it to more than 3,000 degrees Fahrenheit. Plasma gasification or plasma discharge uses extremely high temperatures in an oxygen-starved environment to completely decompose input waste material into very simple molecules in a process similar to pyrolysis. This breaks apart the chemical bonds of feedstock and converts them into a synthesis gas (syngas). Stoichiometric amount of oxygen/ gases may be used for desired reactions. The syngas consists primarily of carbon monoxide and hydrogen—the basic building blocks for chemicals, fertilizers, natural gas, and liquid transportation fuels. The Syngas produced from the Plasma Gasification process is a low BTU gas, that it can be combusted in a gas turbine or gas engine in a power plant to generate electricity. They can be synthesised into any transport oil and into Di Methyl Ether, which can be a complete substitute for Liquefied Petroleum Gas (LPG). In the process hazardous waste loses its toxicity and Inorganic materials in the feedstock are melted and fused into a glassy-like molten slag, which is nonhazardous. It is being vitrified and can be used in a variety of applications, such as roadbed construction and roofing materials. Plasma Gasification has low environmental emissions. It produces only seven percent of flue gas and than 1% dioxins that release by a corresponding Incineration Plant. In the process dioxins and furans get broken into their basic elements and lose their toxicity. It does not generate Leachable bottom ash or fly ash. During gasification, tars, heavy metals, halogens and alkaline compounds are released within the product gas and can cause environmental and operational problems. But it can be addressed with appropriate devices for cleaning of gas and the Gasifier. Moreover Waste Specific Plants may be developed for smooth and efficient gasification. 95

Plasma Torch Mechanism Plasma Gasification Process DETAIL ON PRESENTATION & CONSTRUCTION OF THE EXHIBIT and MATERIALS REQUIRED These have been explained with the help of textual presentation and models of Incinerators and Plasma Gasifier . Models are being prepared with the common materials like plastic boxes/ bottles and pipes etc. APPLICATIONS / EXPANSION There is no absolute innovative thought/ idea in the presentation. It is simply a scientific argument presented in form of an exhibit. It appeals for adoption of such alternative technique for treatment of Solid Municipal Waste which has poses big hazards for both environment and human health. Such alternatives may provide us a clean world for the survival of lives. Also it is worth to mention that, the Gasification Systems have been successfully employed to produce syngas/ electricity by use of the available bio -waste like husk etc. in small scale suitable for rural areas. So there is ample scope for developing new methods for gasification and small & viable gasification units. The PYRO – PLANT developed by researcher like CHITRA TYAGARAJAN is a step forward in the direction. It may help to reduce our dependence on energy produced with fossil fuels and make the villages self reliant with green energy in both Village & urban level besides effective disposal of solid waste and its true recycling.

Plywood boar taken according to requirement. 2. A step-down transformer of 12 volts is fixed on the Board. 3. A convertor kit which converts A.C. to D.C. is connected. 4. 3 Rotary switches are connected in a series with necessary code words 5. The positive end of the conversion circuit and the negative ends of the Rotary switch are connected with a Magnetic switch. 6. The conductor from the magnetic switches is connected with a bulb. 7. A D.C. battery of 9 volts with 2 magnetic switches is connected with the motor on the C.D. tray through the push pup switch. 8. Then a safety wire is connected with the doorbell along with Rotary switch and door through the magnetic switch and the Magnetic switch is connected to a 9 volt battery. FUCTION OF THE PROJECT: 1. The two ends from the step-down transformer carry electricity to the conversion circuit, where only D.C. is produced. It is negative and goes to the relay through the Rotary switch. 2. The electric end of the relay is connected with the holder of the bulb. So when the appropriated code word is given current is flown through the Rotary switch so that the bulb is lighted. 3. The D.C. battery has been connected with the motor on the C.D. tray .So when there is no current flow the motor rotates and the door is closed. Since there is no current flows along the circuit the motor rotates to a particular direction only. Consequently the door doesn‟t open. 4. When current is supplied along the electric circuit due to the Relay system current supply changes its direction and rotates the motor in opposite. So the door is opened. 5. The security wire is connected with the battery through the magnetic switch. So the circuit remains normally opened. If for some reasons the security wire is cut off from the system the magnetic switch gets normally closed. Then the doorbell rings automatically. APPLICATION OF THE PROJECT: 1. The project is convenient for the domestic use. 2. It is very useful at the time of repairing of electric transformers 3. It can be easily used in Banks, ATM counters, Strong Rooms and Office. 4. It can be fruitfully used in Industries where security lapse is a vital problem. 5. It can be used in a Treasury or in a Jail. CONCLUSION: The project we have displayed here is just a small model. We are sure it will be widely used, it can solved a lot of crucial, Critical and difficult problems of the World in security system.

- :SYNOPSIS OF THE PROJECT:-

INTRODUCTION:-

This method proposes a method to control domestic systems using mobile phone, irrespective of the mobile phone model. Method proposes uses the DTMF (dual tone multiple frequency) generated when a keypad button of the mobile phone pressed by the user. The user controls the system by sending DTMF to the access point. Since mobile network coverage is large enough so we can access it anywhere from distant places.

APPARATUS REQUIRED:-

1-DTMF decoder IC (MT8870).

2-Bread board.

3-Decoder 4:16 (74LS154)

4-NOT gate (74LS04)

5-Flip-flop D type (74LS74)

6-Relay driver IC (ULN2003)

7-Relay, 555 timer ic, power supply(12v dc), crystal oscillator, resistances, capacitors, LEDS and connecting wires.

CONSTRUCTION PROCEDURE:-

Take a bread board or Vero board and assemble as per block diagram given below and connect them as per circuit diagram.

USERS MOBILE DTMF 4:16 NOT

MOBILE FOR DECODER DECODER GATE CIRCUIT

RELAYS MOTOR T -FLIP RELAY PUMP, FAN, FLOPS DRIVER LIGHT etc. 108

(Block diagram)

SCIENTIFIC PRINCIPLE:-

DTMF dialing uses a keypad with 12/16 buttons. Each key pressed on the phone generates two tones of specific frequencies. One tone is generated from a high frequency group of tones and the other from low frequency group. The frequencies generated on pressing different phone keys are shown in the Table.

Each row and column of the keypad corresponds to a certain tone and creates a specific frequency. Each button lies at the intersection of the two tones.

When a button is pressed, both the row and column tones are generated by the telephone instrument. These two tones will be unique and different from tones of other keys. So, whenever we say that there is a low and high frequency associated with a button, it is actually the sum of two waves is transmitted.

1 2 3 697 4 5 6 770 7 8 9 852 * 0 # 941 1209 1336 1477 FREQUENCY (HZ)

FUNCTIONING:-

DTMF receiver performs integrated functions of both band split filter and digital decoder and uses switched capacitor techniques for high and low group filters. The decoder uses digital counting techniques to detect and decode all 12/16 DTMF tone pairs into 4 bit digital code from 0000 to 1111 in its output. DTMF decoder MT8870, before registration of a decoded tone pair checks a valid signal duration. This check is performed by external RC-time constant driven by Est (Early steering output).When it gets a valid signal the standard (pin 15) pin becomes high.

After getting the 4 bit digital data, it is decoded by 4:16 decoder to get 16 outputs so that we can get 16 outputs by DTMF decoder. Then it is inverted by NOT gate. The output of not gate is feeding to the clock input of 1-bit memory i.e. flip-flop, here we used positive edge triggered D-flip flop as toggle mode by shorting D-input to Q‟ by which we can do ON and OFF the appliances by using same keys alternately. Then outputs of flip flops are given to the relay driver to boost the power by which relay can operate. Sound system is designed to triggered from relay driver input by using a two 555 timer ic, one as monostable mode and other is astable mode and feeded to speaker, for which we 109

can recognize the sound when appliance is on. So that any appliances can switch ON or OFF directly from 230V ac supply by pressing corresponding keys in the users mobile phone.

UTILITY:-

It can be utilized in:

 IRRIGATION systems i.e. switched ON or OFF the motor pump which is placed far away from a farmer‟s home.

 HOME AUTOMATION i.e. we can control our home appliances such as lights, refrigerators, fans etc from distant places.

 SECURITY SYSTEMS which is used in night or a specific duration of time so that if we forget to switch ON or OFF we can access it easily from anywhere.

Sl No-52 ABHINABA CHULAH

Know Your Fuel! Save Your Fuel!!

Know Your Needs!!! Know Your Energy!!!!

CONCEPT:-

Every combustible material burns when it comes to its burning point. If there is complete combustion, there is less smoke & more heat and in partial combustion more smoke & less heat. The aim and objectives of the CHULLAH is to raise the inner temperature for which the fuel will reach to its burning point within minimum time period. Secondly, the radiated heat can be used to boil water for which there is no extra consumption of fuel can be saved.

REQUIRED EQUIPMENT:

1. One tin can (Cylindrical or rectangular shape) 2. One Shaped pipe (Metallic) 3. Sand, Common Salt, Glass and Asbestos 4. Metallic Pipe 5. Water Container

DIAGRAM:

PRE PAR ATI ON :

The upper cover 111

of the tin can should be open and a hole of 5 to 6cm radius at the height of 15cm from the bottom of the can. The metallic shaped pipe should be placed in the middle of the can. Sand, salt and glass should be filled layer by layer of 3 cm thickness up to the upper level of the can Simultaneously, the inner wall should covered by asbestos. On the top of the CHULLAH a basement should be made to place utensils for cooking.

A copper pipe should be wound round the outer edge of the CHULLAH, one terminal should be connected to a water container and the other should be fitted to a water tap for outlet of hot water.

STATISTICAL DATA:

18 to 20 Kg of wood fuel is normally used in preparation of food for a family of 5 to 6 members.

In this model the wood fuel is reduced to 10 to 12 Kg. So saving of fuel is 7 to 8 Kg per day.

Period of time Fuel used Saving of fuel for one day for one family 7 x 1 7 Kg

Saving of fuel for one month for one family 7 x 30 210 Kg

Saving of fuel for one year for one family 210 x 12 2520 Kg

Saving of fuel for one year for 100 families 2520 x 100 252000 Kg

252000Kg of wood = 252 ton = 120 Trees of 15 feet height and 3 feet perimeter.

Let‟s think – “What amount of fuel can be saved in a country like India?”

The “0” Digits numbers are 10,20,30,100 ets

Squaring Numbers having “0” Unit Digit is very easy

Ex- (10)2 = 1000 02 Zeros (100)2 = 10000 4 Zeros

Cubing “0” Unit Digit is also easy 113

(10)3 = 1000 (100)2 = 1000000

Cubing „5‟ Unit Digit is also easy (5)3 = 103/8 = 125 (15)3 = 303/8 = 27000/8 = 3375

STEPS OF PROCEDURE

7. First the number to be cubed is detected. 8. Then in a number line, “0” Unit number either to is left or right is detected square is detected. 9. If from left addition method is to be followed and if from right substraction method is followed. 10. Numbers between the number to be cubed and its zero unit number is repeated twice. Closed numbers are doubled. 11. Then, this total amount = (T) is multiple with its zero unit number. 12. The value is added/ Substracted with the T Number of time it from the number to be Cube. Maximum 4 time for ease

Ex-1 (1)3 = (Either) = (0+0+1) 1 =1 (OR) (0+0+1) (0+1) = 0+1=1

Ex-2 (12)3 = (100+10+11+11+12) (10+1+1) = 144 10+144+144 = 1440+288 1728

1440 144 +144 1728 Ex-3 (59)3 = (3600-60-59) (60-1) = 3481 60-3481 = 208860-3481 = 205379 114

Ex-4 (3)3 = (0+0+1+1+2+2+3) (0+1+1+1) = 9 0+9+9+9 = 27

Ex-5 (19)3 = (400-20-19) (20-1) = 361 (20-1) = 361 20-361 = 7220-361 = 6859

STEPS.-

1. Fixing of the bamboo stick (5feet) from a distance of approximately 5feet of the pump. 2. Binding the small bamboo stick in the big bamboo stick (as per the height of Oil Leaver). Small Bamboo stick will be fixed a little higher to the height of Oil Leaver. 3. Binding of the rope with Oil Leaver & Brick/Stone (One end with Oil Leaver & another end with stone/brick). 4. Hanging of blank jar in the middle of the rope. 5. Making of one hole in the bottom of the jar (The radius of the hole must be smaller than the radius of LT pipe). 6. Starting the Diesel Pump. 7. Putting the end of the LT pipe into jar.

PROCESS.-

When the diesel pump starts, the small amount of water through LT pipe enter into the engine for cooling the engine. Then the water flows to out side through another LT pipe. The drainage water from LT pipe enters to the jar. The amount of water drains from the Jar by hole is always less than the water enters to Jar, by which the Jar is always with full of water. On the other hand, the jar with water is keeping balance with the stone fixed with end of the rope. It means the weight of stone must be equal to jar with full of water.

If for any cause, the flow of water stops into the engine of the pump, then no water will be entered to the jar. Then the jar becomes empty within 2 or 3 minutes. By which, the weight of the stone will be much more than the Jar. It results to pull the rope which is connected with Oil Leaver and the engine becomes automatically stops.

INVESTMENT.-

It is very no cost & low cost project. The equipment like stone, rope, blank jar, bamboo stick etc. are readily available with most of the farmers without investing any.

OUTPUT.-

1. To save the engine of the water pump becoming seized.

2. The farmers can utilize their time in other productive work without remaining present at the Diesel pump.

A Brief Write-up of the Project

The unwanted heat generated from the Chimneys of different heavy Industries directly responsible for global warming. The poisons gases also pollute soil, water and air. This project is based on utility of waste heat. For this purpose we use normal water in contact of the Chimneys and heavy Industries like Iron, Steal, Cupper etc.So that the normal water creates high pressure steam which helps to run small size external combustion engine which in term runs D.C. generator. The electricity generates from D.C. generators get stored in power house. We get useful electric supply by using step of transformer to power house.

The hot water and vapour that illuminated from external combustion engine is spread in air at high level. So that a cold atmosphere is created. We can collect this water for re use.

It is calculated that about 20-25 K. watt energy can be produce from a normal iron factory for self use. I anticipant that this project must works for energy crises today

SYNOPSIS

INTRODUCTION: The principal aim of the project is to produce electric current from a rice mill. Again the project shows how the atmosphere can be free from the pollute gases, smokes, fumes and dust released by industries. PRINCIPLE: It is based upon the principle of electromagnetic induction i.e. whenever magnetic flux linked with a circuit changes an e.m.f. is induced in it. MODEL: This model is a rice mill. This rice mill is fitted with machinery from grinding rice into rice grain. The rice grain falls on the ground from a height. The moving rice grain fall on a turbine fitted with an armature producing electricity. WORKING: In rice mill, rice is boiled and then dried. Then rice grain and rice husk are separated in grinding section. Then rice grains are mode to fall on the armature associated with turbine and electricity is produced. This electric current is used in the factory. Oil can be produced from rice husk. An artificial magnet can be created by supplying electric current to a cylindrical cupper coil round over a zinc bar. This artificial magnet can be placed at the top of the chinning of the factory. The gas produced from the mill, passes through the Chimney is filtered from dusts. The water utilized to boil rice is purified by potass alum and bleaching powder. Again the water is decomposed in to Oxygen and Hydrogen by water electrolysis process. CONCLUSION: If we produce electricity in this way the scarcity of electricity can be fulfilled. Again in this procedure, water pollution and air pollution can be reduced.
