Anyone with a good grasp of physics and/or electricity?
I have some questions about creating a system that's self energizing/requires minimal initial input for potentially an unlimited output using mutual induction similar to a coil in automotive applications, but more of a looping circuit.

i know nothing, but if you would like i could ask my dad later tonight when he gets home... he's an electrician.. has been for years and years and years
do you think he would be of any help?

the Russians claim they have done it. but they say that they have been unable to reproduce the experement. hehe
according to our scientific laws right now, it is impossible. but the impossible has changed the rules many times before... but i dont think even justa~gurl's dad will be able to help you out on this one. too bad Nikola Tesla is dead, he might have been able to help :)

Thermodynamics says NO!
I have minimal expierence in the type of systems you're talking about but in the past month I've taken an energy systems engineering role at my company. I'll mostly be doing work on hybrid system designs using various energy storage methods. It seems to me in order to do something like this you would have had to find a material that super conducts at higer temperatures than just above 0 Kelvin :) Currents can flow in super conductors for years and years if they are kept cold. I have built a couple Tesla Coils in my day using neon sign transformers, I was getting a good foot and a half spark off one of them :) Quote:

Simple. All you need is a microwave, a jar of Ragu (extra zesty) spaghetti sauce, some duct tape and a duck. If you can't figure out how to join them all together to create a perpetual energy generator, then you should go back to Kindergarten!

I'm thinking of something along the lines of a coil and spark plug system. In most automotive applications, it's around 50 000v that ends up produced in a coil. It takes a couple milliseconds to achieve saturation in the rings, but if you set up a few coils and timed them to charge at intervals it'd solve erratic surges. Send the energy through a couple capacitors and resistors and send it back through to the coil and the rest to some batteries. Wouldn't it be a self sufficient loop? If I start small, and keep it around 50 000k, or less, wouldn't there be fewer problems with wires over heating and finding super strengthed materials? It seems like such a simple idea in my head, gonna give it a shot next week. Last edited by Goat; Nov 09, 05 at 11:05 PM.

You'd have to draw it out because it doesn't really make much sense to me. The automotive coil you talk about is just a standard transformer which has losses associated with it. Coils don't really charge either, I'm assuming your talking about an RC circuit charging to fire the primary coil. In a perfect world an inductor would be lossless but its not, so there is an internal resistance in series associated with both the primary and secondary. Which means you have a power loss on both sideds.
http://hyperphysics.phy-astr.gsu.edu...transf.html#c1 This web page explains it. You can't sustain 50kV on the secondary with just a 12V DC battery. Obviously you need some sort of switching circuit. In order to generate the mangetic field / flux in order to drive the primary coil. As shown in that web page the output voltage of a transformer is equal to the ratio of turns between the primary and secondary coils, but you don't get something for nothing. P = V*I, Pin must = Pout therfore your output current is inversly proportional to the ratio of windings. V goes up I must goes down. If you run your output through a resistor you are just going to lose more power. P = (V^2)/r. Contrary to what you said, the higher the voltage the more efficient it is to transfer power over a power line. P is also = (I^2)*R So power loss is proportional to the current squared. So its more efficient to transfer at high voltages and low currents. once you've got that all sorted out then you have to worry about charging the batteries which has another huge set of inneficiencies associated with it. I have a bit of experience with different types of batteries as I work for a company that develops hybrid fuel cell systems. hope this helps a bit. I'm not very good at getting my ideas across so let me know if you need better clarification. Again I don't know what your experience is but you should definately do a google search on Telsa Coils and resonant circuits. Tank circuits would also be a good words to toss in there as well. I'm not sure what your background is in electronics so disregard this if you already know. Tesla coils are pretty sweet. Where are you planning on doing your experiments, you've peeked my interest :) I had a huge interest in HighVoltage experimentation about 7 years ago :) Last edited by Leviathan; Nov 10, 05 at 10:28 AM.

Thanks for the info man. I went over what I had planned to do and found arse loads of flaws and holes. Went over it for a couple hours with my brother and plan on putting something in the works later next week. I live in the middle of no where, other wise i'd say the more help the merrier. I dropped the coil idea and am planning on using a self generating electro magnet and mutual induction. Thanks for the recommended reading and the help!
Hybrid cells for automotive applications? What company do you work for? Last edited by Goat; Nov 11, 05 at 02:04 AM.
