enjoy!

To increase the ammount of current this circuit can handle, all you would need to do I beleive is add more transisters and resisters in parallel, once you look at the circuit you will understand what I mean, You will see six transisters that take the brunt of the current load, simply add more and It should be able the extra current, but this circuit can already handle spikes of more than 100 amps.

Yeah, I saw that on a search of google myself. The problem is that you still need a power supply, called the secondary in the schematic. Your current output is not limited by the number of transisters but by the power of the secondary, which in the case of the schematic is 35 amps.
