Engineers Tested a Jet Engine Running on Superheated Plasma Instead of Fuel Engineers have been experimenting with propulsion concepts that replace traditional combustion with superheated plasma to generate thrust. In laboratory test environments, plasma-based systems have demonstrated sustained operation without burning conventional fuel. Rather than relying on chemical explosions, plasma propulsion uses electrically energized gas to produce high-temperature, high-velocity exhaust. While not ye
