Nice short, informative video. But on the point of free electricity, Kathy completely misses the point. Granted, Tesla never spoke about free electricity, but wireless electricity, if developed, would necessarily be free because there would be no way to meter it, which would be a good reason for Edison, Morgan and Westinghouse to ignore it. If, on the other hand, for some reason, they did want to provide free electricity to the world, wireless electricity very well may have been developed on a large scale. The reason wireless electricity wasn't developed wasn't that it couldn't work, but that it couldn't turn a profit because it is impossible to meter. Pointing out that Tesla never spoke of it misses the forest for the trees, because this is irrelevant. What is relevant about wireless electricity is that it can't be metered, thus it can't be a profitable service to base a corporate empire upon.

I think Debunk is a bit of an overstatment. That is like saying James Watt should get no credit for the steam engine because they had spinning toys powered by steam in ancient egypt. What amazes me is that along with the electrical stuff Tesla also did fluid dynamics: See Tesla valve, Tesla turbine.
