Re: caps boostin input pwr?
A cap does not produce anything. It only stores a charge provided by another source. To get everything operating at 18V he either used a totally seperate externally regulated alternator that was isolated from the rest of the vehicle's electrical system or used a large switching power supply to up the voltage (I know that US Amps made one of these for this purpose). Either way, the caps had nothing to do with the change in voltage.
Artificial Intelligence is no match for Natural Stupidity.
Never underestimate the power of stupid people in large numbers.
