To generate very large amounts of electrical power with a modest initial input source, try this as an experiment?
1) Build a simple push-pull occillator out of, say 2N2222's and, say, a 30-35 VA transformer from Radio Shack or the equivalant. Use as the occillator power source: a 1.5 VDC battery.
2) The transformer, wired backwards with the occillator going to the secondary, steps up the output from the ocillator from about 1.5 VAC to 12 VAC on the primary (mains) coil. Take a long wire and loop several turns around this transformer to a much larger, or set of, transformer(s), thus using the occillator transformer as a trigger coil for the Back EMF to the whole bank. Rectify the output of this bank to charge up a bank of batteries similar to the first one. This bank can be wired in series or parallel---or both---as required.
3) Take 1.5 VDC from the large output bank and run the occillator with that power so that the system is self-generating indefinitely. (The positive side of the battery can be reduced in voltage with a resistor, if necessary.) The excess power is used to run whatever you like.
There's a thread on Overunity that illistrates this idea very well that's entitled: "Milliamps in, many amps out!" Unfortunately, my time is limited on this borrowed computer, or I'd look for it. There's a drawing of the schematic on the paged reply. It tells the whole story with one picture.
NOTE:
The large bank will probably send strong power spikes through the trigger main coil to the secondary, thus stressing the @2N2222's with considerable power surges. In that case, wire one or more diodes, even including properly valued zeners, to the positive terminal(s) of the output bank, thus harvesting the conducted Back EMF from this source as well.

>>Yes, thank you for asking. I do have a schematic for an experimental test system, but I can't upload it without a scanner on this computer. I can try on another computer as a software experiment at a local junior college, which does have a scanner. (The drawing needs work, but it's ready now. Some explaination(s) may also be necessary after uploading it.)

Can't seem to locate that 'Milliamps in, many amps out!' thread bigM.
Are you sure the thread title is correct ?
I must have missed it first time around.

>>I made a copy of the data picture file, and now I can't find it in my notes! Frustrating!
You might have a point?!?!
I just can't prove it. >:( ??? ::) :-\
That was the title I remember. A small ocillator was paralleled onto a larger coil and
that trigger occillator caused a power surge with Back EMF to be harvested with a full wave bridge. Really. Simple and easy to prove, the way the posting Member drew it.
Well,
I'll have more time to try and find it tomorrow,
if I can find it. :(
I'll also try and upload my schematic. On a borrowed computer. :-\

>>Okay, I tried. I wrote an explanation of what I was trying to do before I tried to upload my schematic in three attached files, then I scanned the 3 pages with the American software package PaperPort, and
the computer locked up when I tried to upload the whole post! It wouldn't unlock at all, either!
It would Spell Check for me, however. Really! A selective computer/software glitch?!
Each page was a typical 8 1/2 " X 11" sheet with lines drawn in pencil on them. I don't think each whole page would have amounted to 250 KB?
I could also do it in .PDF or possibly WinWord, as an alternative, but the reader would need a software package compatible with that particular format to download the data.
Oh, well, the next best thing I can try is to reference other posts on Overunity to try and describe what I mean and have Members look at other, similar posts to gain insight from them?
Any ideas on dealing with software issues, anyone?
P.S.
This post did actually upload and run, obviously, so the .JPG attachments were the hangups.

Hi Lee,
Attachments have been limited to max 100kB in filesize until recently, now I am not sure but if you have bigger than 100kB files then you may wish to go the Upload section of this Forum (see it as Upload icon in the upper left column), here is a link for it: http://www.overunity.com/index.php?action=tpmod;dl=upload
You may upload max 5MB files there. (JPG could not have been a problem but the size as attachment.)
rgds, Gyula

Now, for modifications, I would take some of the voltage through two transformer tiers (100V to 12V to 1.2V) and then re-transform that with back EMF to 110V.

'A' is the input of 1.2 V from the second tier of step down transformers.
(Radio Shack sells a 110VAC-12VAC line transformer with a .45 A secondary.)
'B' is connected to the other side of the primary to step up the voltage like a Tesla coil.
'C' is an optional diode to prevent back EMP power surges from cooking a secondary coil or a transistor oscillator that drives the circuit.
This way, the secondary of the step-up set of transformers act as a counter-wound bifilar coil.
It might be better to use toroids instead? Caduceus coils? In series or parallel?
The parallel output(s) can be rectified to a bridge and back-fed to the battery bank in the drawing above. Or to a capacitor bank and then to the batteries? The latter coils I mentioned should inherently be better for OU functioning.
The possibilities are numerous, if one uses the imagination.
