Nikolai Tesla was a genius. No doubt about it. He invented the idea of the internet way back in the 1890’s right after he invented radio. In Belgrade there is a museum dedicated to him. At one point this giant among intellectuals and practitioners of science suggested using high intensity electromagnetic fields to transmit power over long distances. His idea was to create powerful electric fields that people could use to drive electronic devices wherever they were. This is exactly the same idea as the wireless charging devices you see on the market at the moment, but MUCH BIGGER! And not so different from the idea of solar energy. Here is a picture of such a coil powering a series of fluorescent tubes that are not connected to the device other than a flux linkage from the coils.
