Volume 4, Issue 5, May – 2019 International Journal of Innovative Science and Research Technology ISSN No:-2456-2165 A New Type of Renewable Resource: The Natural Thermal Expansion and Contraction Energy of Matter Abdulkobi Parsokhonov Khusniddin Iskanov Dept. of Electroenergetics, Jizzakh Polytechnic Institute Dept. of Electroenergetics, Jizzakh Polytechnic Institute Jizzakh, Uzbekistan Jizzakh, Uzbekistan Abstract:- A new type of renewable resource is kinetic energy of individual atoms [3]. Conversely, a suggested. Permanent temperature changes in the decrease in the kinetic energy of atoms accompanies environment are accompanied by enormous flows of contraction of matter. The increase or decrease in the energy. The forces that arise by the natural thermal kinetic energy of atoms is governed by the increasing or expansion and contraction of liquid and solid matter, decreasing temperature of the substance, which in turn due to day and night temperature differences in the depends on the environmental temperature. The environment, can be deployed to generate useful energy. environmental temperature will constantly change in The problem is how to transform the very slow nature, and day and night temperatures are usually processes of expanding and contracting into fast linear considerably different. Thus, each day, all matter will or circular motion. Here, we present a pilot model of a periodically expand and contract under the influence of the device that implements a way of accelerating the temperature in the environment. This expansion and thermal motion of a working liquid to produce contraction will continue year-round regardless of whether electrical energy. The power of the new type of machine the day is sunny or not. Therefore, the process of natural depends on the initial volume of the working liquid, the thermal expansion and contraction of matter is renewable coefficient of thermal expansion of the liquid, the and matches with the definition of a renewable resource. pressure in the sealed balloon that holds the liquid, and The forces that arise during these processes can be used for the rate at which the environmental temperature generating useful energy. In addition, according to the changes. The working principle of the device, and the definition mentioned in [4], the term “renewable energy” experimental results obtained for the chosen covers energy flows that occur naturally and repeatedly in parameters and design, are described. Our results show the environment, and the ultimate sources of such energy that the use of a working liquid with a higher thermal are the sun, gravity, and the earth’s rotation. If start from expansion coefficient, a larger initial volume, and a these determinations the expansion and contraction of higher working pressure can potentially generate much matter are the results of environmental temperature more power. changes. The natural temperature changes caused by sunlight, weather, and earth’s rotation for a given locality Keywords:- Contraction; Expansion; Natural; Renewable; per unit of time can be regarded as energy flows. These Thermal. environmental energy flows will be transferred to liquid and solid matter, and the kinetic energy of the individual I. INTRODUCTION atoms of which will increase or decrease resulting in expansion or contraction. The world’s demand for electrical energy is increasing year by year. The share of renewable resources The immensity of the natural flows of this renewable in the generation of electricity is growing too, but it cannot resource is obvious [5]. Temperature changes on the globe meet the demand. In 2016, 79.5% of the energy consumed constitute inexhaustible energy flows. Under the influence was produced using exhaustible fossil resources [1]. This of these energy flows, heat transfer occurs from the encourages the search for new types of renewables. environment to matter or vice versa depending on the According to [2] , the main renewable energy resources are difference in temperature between matter and environment. hydropower, wind, solar, geothermal, biomass, ocean The heat transfer will force matter to expand and contract waves, offshore wind, marine current, ocean thermal periodically. The rate of these processes depends on the energy, tides, and osmotic power. Here, in the present environmental temperature ramp, and it is in principle paper, we suggest a new type of renewable energy considerably slow but continuous. Not taking into account resource: the natural thermal expansion and contraction of expansion and contraction of matter can sometimes energy of matter. So, let us first discuss whether thermal result in undesirable consequences. For instance, if railway expansion and contraction energy can fall within the tracks are laid without any interval between them, the category of renewables. heavy thrust forces that arise by increasing temperature of the rail can lead to curved rails. Heating of a sealed liquid Several definitions of renewables can be found on will lead to high pressures, while cooling will result in Wikipedia. The main requirement is that the resource must contraction of the liquid and a high vacuum. Thus, when be natural, renewable, and ecological and can operate discussing thermal expansion, one should know about its without the efforts of humans. The thermal expansion of hazards and the ways to avoid them. Nevertheless, there are solids and liquids is associated with an increase in the plenty of useful applications of thermal expansion and IJISRT19MY132 www.ijisrt.com 83 Volume 4, Issue 5, May – 2019 International Journal of Innovative Science and Research Technology ISSN No:-2456-2165 contraction [6]: for solids, bimetallic strips, hot riveting, and tire fitting processes; for liquids, liquid-in-glass II. CHOICE OF WORKING LIQUID thermometer; for gases, dough rising processes, motor engines, and hot air balloons. Here, we offer a new way of The basic problem of producing energy by natural using thermal expansion and contraction of matter: thermal expansion and contraction is how to transform the production of electrical energy. Our research on obtaining relatively slow processes of expansion and contraction of useful energy from thermal expansion and contraction solids and liquids into fast linear or circular motion to forces started in 2015. The main concept, basics, and generate electricity. The linear expansion of solids, l , is capabilities of this form of energy production, and some proportional to the change in temperature T [9]: related work, are discussed in [7]. The patent for the invention of the method of generating electricity from l =l0T, (1) thermal expansion and contraction of matter was registered in May 2018 [8]. The pilot model of the device, which can where - is the coefficient of linear expansion and l0 – transform forces arising from temperature changes in a is the initial length of the material. The volume expansion is liquid into targeted mechanical motion to produce electricity, is presented in this work. The rest of the paper is V=V0T, (2) organized as follows.

CONSTRUCTION, DETAILS AND PRINCIPLE is required to catch the fine movements and transform them OF OPERATION into fast motion because of the small thermal expansion coefficients. Liquids have some advantages in this respect. The function of the pilot model (Fig. 1) is to show There are two factors that are beneficial in liquids: first, as whether it is possible to generate energy with slight seen from Table 1, the expansion coefficients are several environmental temperature fluctuations. Because of the times bigger in liquids than in solids; second, for solids, availability of details and parts, the pilot model was only linear expansion can be used, whereas for liquids designed for a small temperature diapason. This diapason volume expansion can be employed, increasing the effect can be shifted along the entire temperature span that threefold. For these reasons, a liquid was used in our pilot encompasses changes in temperature from night to day. model. Table 1 shows that ethyl alcohol can give the best Shifting can easily be realized by closing the release valve results due to having the highest coefficient of thermal of the filled balloon at a certain temperature, and this expansion, followed by gasoline, glycerin, and water. It is temperature will serve as the central point of the important to comply with the safety conditions when ethyl temperature diapason observed. The model consists of alcohol or gasoline is used because both are highly widely available materials: a 0.065 m3 volume balloon
