There was a great deal of debate between the two as far as AC vs. DC, with Tesla being the advocate for AC, which won out in spite of Edison going around electrocuting dogs with it as a demonstration of its dangers.
Tesla did manage some through air transmission of electricity, in Boulder, Colorado-no one knows exactly how. He wound up there after fears of the dangers of his experiments drove him out of New York City, then off of Long Island.
Xcel energy actually still runs a hydro plant that was the first in the world to generate AC, based on Tesla's theories, the Ames plant, built back in 1896.
