The ‘physics-defying’ EmDrive actually works, NASA declares in peer-reviewed paper
NASA has a new engine that seems amazing. It is an electromagnetic drive. On a side note, I wonder if this tech was used for the catapults on the new Ford Class carrier.
It has been nearly two decades in the making, but as NASA will tell you, hard work absolutely pays off. Especially when that payoff comes in the form of the Electromagnetic Drive (or EM Drive), which appears to defy physics, or at least physics as we understand it today.
Last week, NASA’s peer-reviewed EM Drive paper was published under the title, “Measurement of Impulsive Thrust from a Closed Radio-Frequency Cavity in Vacuum” as an open-access “article in advance” in the American Institute of Aeronautics and Astronautics (AIAA)’s Journal of Propulsion and Power. It’s a monumental achievement for NASA, which has been grappling with the concept of the propulsion system since it was first proposed back in 1999 by British inventor Roger Shawyer.
In theory, the EM Drive doesn’t use rocket fuel, but rather sends microwaves back and forth within a conical metal cavity in order to produce thrust. As per Shawyer’s original estimates, the unprecedented efficiency of the EM Drive could send a rocket to Mars in only 10 weeks. Sound too good to be true? According to physics as it is understood today, it is. That’s because the EM Drive doesn’t adhere to Newton’s third law, which dictates that all action has an equal and opposite reaction. The EM Drive, however, seems to produce thrust without pushing anything else back.
The folks at NASA decided to put an actual EM Drive to the test, and the results of their experimentation comprise the contents of the newly published paper.
