Plasma propulsion engine - Alchetron, the free social encyclopedia

Engineers in the United States have achieved a major breakthrough by testing a plasma powered jet engine that operated for seventy straight hours without using any fuel. Instead of burning jet fuel, the engine generates thrust through superheated plasma, creating propulsion in an entirely new and cleaner way. With no combustion and zero emissions, this technology could transform the future of flight. The success of this test brings the possibility of aircraft that fly for extremely long periods
