This 'free' energy technology has been around for over a hundred years, since Tesla theorized and even demonstrated a motor that ran on it.
Tesla died under mysterious circumstances and his lab was destroyed in a fire and explosion and nothing much has been heard since, other than a long campaign to discredit him and steal his patents.
Don't hold your breath. This one is locked up deep in the bowels of Exxon.
Read Nick Cooks "The Hunt For Zero Point". A great read.
Tesla is gone but not forgotton.
"They" can steal a patent right from under your nose and the dumb sheep dont even blink :-)
