  • Zilano Design for "Reverse Tesla Coil" Free Energy Generator
    Zilano Design for "Reverse Tesla Coil" Free Energy Generator Summary Document A for Beginners by Vrand Thank you Zilano for sharing your very interesting design and we all wish you the very best, keep up the good work! Energetic Forum http://www.energeticforum.com/renewable-energy/ This is a short document describing the work of Zilano as posted on the Don Smith Devices thread at the Energetic Forum so that other researchers can experiment and build their own working free energy generator to power their homes. Zilano stated that this design was based on the combination works of Don Smith, Tesla, Dynatron, Kapanadze and others. Design Summary Key points : - "Reverse Tesla Coil" (in this document) - Conversion of high frequency AC (35kHz) to 50-60Hz (not in this document) "Reverse Tesla Coil" is where the spark gap pulsed DC voltage from a 4000 volt (4kv) 30 kHz NST (neon sign transformer) goes into an air coil primary P of high inductance (80 turns thin wire) that then "steps down" the voltage to 240 volts AC a low inductance Secondary coil centered over the primary coil (5 turns bifilar, center tap, thick wire) with high amperage output. The high frequency (35kHz) AC output can then power loads (light bulbs) or can be rectified to DC to power DC loads. Copper coated welding rods can be inserted into the air coil to increase the inductance of the air coil primary that then increases the output amperage from the secondary coil to the loads. See the below diagram 1 : Parts List - NST 4KV 20-35KHZ - D1 high voltage diode - SG1 SG2 spark gaps - C1 primary tuning HV capacitor - P Primary of air coil, on 2" PVC tube, 80 turns of 6mm wire - S Secondary 3" coil over primary coil, 5 turns bifilar (5 turns CW & 5 turns CCW) of thick wire (up to 16mm) with center tap to ground.

The features, working principle and elements of the BCPMG are analyzed. The BCPMG is developed from the iron-cored “bifilar” coil topology based on (1) in an attempt to overcome the problems with current rotary type generators, which have so far been dominant on the market. One of the problems is armature reactance , which is usually bigger than resistance . The circumstance creates difficulties for designers and operators of the generator. That is why patented technology is offered to partially remove or absolutely neglect the reactance of the machine. Drawings of the PMG parts and assembly are added. A finite element magnetic model (FEMM) is presented and analyzed. Also, this thesis contains an experimental analysis of the PMG characteristics, such as no- load losses and EMF vs. speed, loaded voltage drop, power output and efficiency vs. load current at different speeds. 3 TEI-09, O.Lyan, V.Monet Research of PMG with compensated reactance winding LIST OF TABLES 1.1.

    December GETTING IT TO WORK IS A LOT EASIER THAN EXPLAINING WHY IT WORKS 17, 2013 Overunity Joule Thief (The circuit has almost nothing to do with Joule James, I Just lie to remember him) 1 Leonard Teasca, BSc Electrical Engineering Phone No: +40 723 520 684; Email: [email protected] December GETTING IT TO WORK IS A LOT EASIER THAN EXPLAINING WHY IT WORKS 17, 2013 1.Introduction This presentation is intended for both technical and nontechnical people so if you see an inexact nontechnical explanation keep in mind that it is not my intention to mislead or insult anyone’s inteligence. The Joule Thief is one of many overunity devices out there. It has been around for many years yet is stands as a simple voltage booster. I think that is why it still exists and also because they can’t control the internet (we know they tried). A JT (Joule Thief) is a very simple and easy to build self oscillator. ! To understand the concept of an oscillator think about switching the light in your bedroom on and off once every second. That will give you a switching frequency of 1 Hertz. Now imagine the you have an electronic device that does this for you automatically. So now the light in your room will oscillate with the frequency of 1 Hertz (will turn on and off every second)...” I believe that the JT oscillates at the resonant frequency of the circuit (I’m unable to determine this due to lack of equipment – LCR meter) The working principle of such a circuit is simple at first glance but simplicity is the genius in all.

If this is truly cold current you should be able to run it through a resistive load and the resistor should cool down. Suggested loads after diodes on 'cold' side Running the system without a load at Radiant Output will give you completely false readings at output, besides, Radiant will definitively Retro-Feedback into your circuit through Input (before diodes) and could blow your Mosfet's and other components. So, there must be at least a Load Resistor at Output at all times...but remember that Radiant goes through resistance without any effort, so the resistor must be set according to RE tolerance...meaning, a very low resistor of lower Kilo ohms, would do absolutely nothing, Nada. (exactly what load resistor is best?) -Self ballasted fluorescent with fitting - 125 W/120V - you will just need @ 2000 Hz in output...spending @800Hz input. Have a group of CFL's or at least one connected to output. You have to slowly start increasing frequency, till you start seeing the CFL's flashing and going brighter as you turn frequency higher, until you get to the Max Point of steady brightness, from there you start going up...but watch the meters or will blow CFL's.

  • Testing Feasibility of Inductive Power Coupling for Modern Applications
    TESTING FEASIBILITY OF INDUCTIVE POWER COUPLING FOR MODERN APPLICATIONS by Andrew Burman BioResource and Agricultural Engineering BioResource and Agricultural Engineering Department California Polytechnic State University San Luis Obispo 2016 TITLE : Testing Feasibility of Inductive Power Coupling for Modern Applications AUTHOR : Andrew Burman DATE SUBMITTED : June 3, 2016 Art MacCarley Senior Project Advisor Signature Date Charlie Crabb Department Head Signature Date ii ABSTRACT This project takes two bifilar tesla coils and uses them to find a % efficiency of power transfer as distances between the coils decrease. The reason this experiment is being conducted is to find possible implications for wireless charging of vehicles using similar style coils. This project conducted experiments on 60 Hz, 400 Hz, and 1 kHz frequencies for a small input signal. The general conclusion is that as the frequency increases more power can be transferred and higher efficiency of power transfer is seen. This project also concluded that it could be possible to get higher efficiency at a greater distance with a higher input power frequency. There would of course be tradeoffs for achieving a certain charge time, but this project is concerned in the possibility of a greater gap being used so that charging could be done on a wide variety of vehicle applications. These applications would range from public transport, domestic, or freight. iii DISCLAIMER STATEMENT The university makes it clear that the information forwarded herewith is a project resulting from a class assignment and has been graded and accepted only as a fulfillment of a course requirement. Acceptance by the university does not imply technical accuracy or reliability.
