Tesla Patent 685,957 - Apparatus for the Utilization of Radiant Energy

Tesla Patent 685,957 - Apparatus for the Utilization of Radiant Energy: My own experiments and observations, however, lead me to conclusions more in accord with the theory heretofore advanced by me that sources of such radiant energy throw off with great velocity minute particles of matter which are strongly electrified, and therefore capable of charging an electrical conductor, or, even if not so, may at any rate discharge an electrified conductor either by carrying off bodily its charge or otherwise.
