With a superconductor, you can create a much more powerful electromagnet through which the coil will still produce a lot of voltage even when turning very slowly. Thus, you can use a much simpler gearbox or even just skip it entirely.

My favorite application for room-temp superconductors is low-speed generators. They have exactly one application, but it’s big: Wind towers without a giant gearbox. Wind power is cheap, but without the truck-sized gearbox with a bazillion moving parts that you can’t lift without the biggest cranes known to man, it’s even cheaper.

Man we got war droids already and the people who really need ones that work are NOT making theirs shaped like a guy.

I can’t be arsed to dig up the equation, but it may mean that the wind has 200 times more usable energy, which I think is a cube function of its speed. Wouldn’t be 2000 knots in that case
