Tesla coils are commonly used to detect potential leaks in vacuum systems. They're also used to fry the GDI infantry in Red Alert, of course. It's a pity that funky old bastard Tesla wasn't more like David Bowie portrayed him in "The Prestige".

I've heard the same thing.
But then again, i've also been lead to believe that you can stick your hands right into a M/A reaction chamber and jiggle some stuff around to bring the "mains back on line".

So what is the role of frequency?
If I had a 12:240 turn transformer, and drove it with 12 volts at 0.01Hz, would you expect my multimeter to show a peak voltage of 240 volts (or thereabouts) across the secondary?
That's an interesting question. There is continuous change in voltage so it's theoretically possible but the coils would have to freaking huge! Obviously, this is only a theoretical exercise as that frequency is way too low to be practical but the simple step up/step down law of ratios of turns in the primary and secondary still apply. Using higher frequencies allows smaller components to pass the same amount of power. I believe the that's why the U.S. Navy uses (or used to use) 400hz on their ships.

Navy ships only use 400 Hz power for certain high precision electronics. Weapons and Navigation stuff. The rest of the ship is powered by regular old 60 Hz AC.
Lots of aircraft equipment runs on 400Hz also.

Solar? Wind?

It was kinda a joke.. Just not a very good one. I was making light of two total opposite side of things..
However, as far as wind goes... Soon as this bad boy is out
