How does a compacitor work?

Question

Okay, i'm planning on a continous closed loop system. Where i have a generator to produce power onto a compacitor. Now, would that compacitor act as a battery? Okay here's to make it more clear. My power source is used in the begining to jump start the closed loop system, then once i can charge enough power into the compacitor i can discontinue the main battery resource and let the compacitor run the motor, which the motor runs the generator to charge the compacitor. Get it? It makes it a closed loop power resource. I can use resistors and diodes to limit and keep my power running at a constant direction and speed... Do anyone think this will work? why? Thanks.

Answer 1

This won't work. It's called a perpetual motion machine (which does not exist to our knowledge).

Conservation of energy is the basic principle that governs these types of systems. Each time you convert the form of the energy, you lose part of the energy (often as heat), so you end up with less than you started with.

The generator is the device that converts energy from an engine into electricity. The output from the generator, driven by an engine, is the most power you can get out of this system. Now, when you store the electricity in the cap, you lose some energy. When you run the motor from the cap, you lose more. If you use the motor to run the generator, still less would come out. As soon as you disconnect the engine driving the generator, the whole set of devices would quickly grind to a halt, wasting whatever energy you put in to start it up.

Again, a fundamental thermodynamic law is that you can only get the energy out that you put in, minus any losses.

If you are under 12 years old, this question shows a very intelligent mind, looking at new ideas.

If you are over 12, well........spend your brain-power on something else.

Answer 3

Yeah, we get it, but you don't. Bilruss is right, this is a perpetual motion machine, and the do not work. Nice dream, but you really should spend you time on practical things, such as making a fuel cell out of common household things such that air and fuel gas in, like methane, or propane, and you get electricity, heat, and water out of it. They exist now, they just need to be dirt cheap so that anyone can have one for their home, or vehicle power needs.

Answer 4

compacitor? combination of capacitor and compactor?

You are trying to make a perpetual motion machine, and you can't, with or without a compacitor.

It has zero chance of working. Every part of the loop uses some power, so when you get to the beginning you have less than you started with. Always.

Analogy:

Start out with a £5 note. Go to a bank and change it for five £1 coins (minus a service fee). Go to a different bank. Change your coins for a £5 note, minus another service fee. Repeat until you have several million pounds!
