Tesla tower is another beast. Tower was not a generator. It was a transmitter to create standing EM wave between ionosphere and Earth surface, so making transmitted energy available at any location. There is an effect known in coaxial cables - when a cable length is integer multiply of transmitted wave length, then losses are at minimum. Tesla took a view at Earth and its ionosphere as at short coaxial cable, and thought that it would be a great idea to use it for energy delivery.

Really, I'm not shure that this was a good idea. Kind of HAARP, but with magnitude orders more power and all that stuff. Tesla didn't examine any side effects of saturating Earth atmosphere with enormous amount of EM power.
