Holy shit.
I never doubted Tesla, for the record. In my engineering illiteracy, the idea seemed obvious when I read about it, and also seemed like the kind of thing companies would happily squash for money. But holy shit. If we have the time and ability to get this off the ground?
Static electricity comes from the sun like every other source which is available in meaningful quantity (except geothermal which is kind-of-half-solar).
