Nikolay Tesla's research in 1897 had confirmed that power could be wireless sent to electronic devices without the use of wires. If you can send data through the air waves so can power. This theory has been classified as "Inductive charging" which uses a electromagnetic field to transfer energy between two objects which can be used to charge batteries or run devices. Nikolay had built a tower by the Nigara Falls where he wanted to use the power from a renewable source of power, a hydro-electric dam and distribute the power wirelessly to cities and towns. His life's work was verified but never completed.
