T.H. Moray Professor of physics inspired by Tesla, said to have produced a machine capable of extracting useable energy from “cosmic rays”. These rays have been associated with the quantum vacuum by some. Documents exist which appear to substantiate the fact that Moray produced electrical energy with no known input energy.
