I was just musing the other night about Tesla's AC and how it revolutionized electric wiring, with the step-up transformers and all.
Well, if you start with, say, 100V, you need to carry 1 amp to power a 100W light bulb.
But if you step up the 100V to 1,000V, you only need wire that can carry
100mA.And if you step it up to 1,000,000V, you only need 100 _micro_ amps.
So, logically, if you could step up the voltage enough, you shouldn't need any wires at all!
Unfortunately, the darned electrons arc over to stuff before they get to the destination transformer. )-;
But, in fairness, those guys were just discovering electricity for the first time, and NOBODY knew anything about how it might behave.
