Fuel-free engine concept is feasible: NASA scientists demonstrate

NASA Eagleworks scientists have demonstrated that EmDrive, a fuel-free engine concept which has caught the imagination of space enthusiasts around the globe despite defying the main laws of physics and workability, is not impossible.

A team of scientists at NASA Eagleworks has successfully produced thrust in a vacuum without any sort of propellant. It may be noted here that Eagleworks is dedicated to testing humans’ wildest theories of spaceship propulsion.

The futuristic engine produces thrust without any type of fuel. Instead it uses microwaves bouncing around a conical, enclosed device. The theory states that the momentum of the bouncing microwaves is higher at the engine’s wide end, which means the entire system should experience thrust.

The scientists demonstrated this unique theory with by successfully generating a force of 1.2 ± 0.1 mN/kW, which is higher than photon thrust.

Previously, several physicists had dismissed EmDrive as “impossibility.” But, the new paper published under the title, “Measurement of Impulsive Thrust from a Closed Radio-Frequency Cavity in Vacuum” has hinted at NASA’s eventual plunge into the technology.

The scientists reported their research in the Nov. 17th edition of the American Institute of Aeronautics & Astronautics’ journal of Propulsion and Power.
