From: Tim Williams on 3 Jul 2010 02:15 Let's say you had a really high voltage, low current source. Not very useful. Think nuclear battery, or lightning. So let's say you use it to charge a stack of caps. Then you rewire the caps in parallel. It's like an inverse Marx generator, or a synchronous C-W multiplier. How would you do it?

Why would you go through all the trouble when you can get 1000x more power from your outlet? Say you have a 1M van de graff, you get maybe 1uA from it... thats just 1W. No matter how you configure it you'll never get any more power from it. Your caps are in series which means the voltage across them is 1/n of the total voltage. When you wire them up in parallel your new total voltage is 1/n. e.g., suppose you have 1M voltage and 1000 caps in series. Your new voltage would then be 1000V and your current would be 1000 times the original. i.e., your just making a transformer. Any time you have a predetermined amount of energy you can only ideally transform it into a different "form"(since energy can neither be created nor destroyed).
