audio amplifier as a power generator (instruction)

[dxer_87]

Here is the proposed schematic. I don't know how to make driver, but 3-4 transistors should give effect.

Also, when voltage doubler used or bridge rectifier with electrolytic cap, I was wounding a little noplis on it taken from the output of a fat coil. This can boost energy efficiency, especially on higher voltages as proposed in the last schematic.

If you don't know how to make a driver, just use 555 in sawtooth mode (use 78L05 for this circuit, freq. is regulated by capacitance)

and voltage follower based on a transistor (emitter follower) supplied with 25V, play with resistors:

Thanks to all that donate. I won't stop informing people about free energy systems. We can change situation worldwide and also save old electronic components from recycling. I had Jawik like system that holds even 100V, feeling sorry for my fault I proposed sth solid state that can really work .

If you have old crt tv or monitor, reuse the cable around the screen and make a coil. Thus you can have this solid state. If you once start such system, you may start from it an amplifier like from a battery .

I am thinking of sth like these:

I think the easiest way would be using a simple near sawtooth gen on 3 transistors. If voltage doubler is not that efficient, look at this video, i think it's interesting method of rectifying and you have another pin gnd to utilize...
