Teleforce is a charged particle beam projector that Nikola Tesla claimed to have conceived of after studying the Van de Graaff generator. Tesla described the weapon as being able to be used against ground-based infantry or for anti-aircraft purposes. It was mentioned publicly in the New York Sun and The New York Times on July 11, 1934. The press called it a "peace ray" or death ray.
