A New Rocket Engine Design? It’s official. NASA recently confirmed the EmDrive Thuster actually works, supplying 720 milliNewtons of thrust. The thrust was reported in a report issued by NASA. But here’s the funny thing. NASA reported that “not attributable to any classical electromagnetic phenomenon.”
Huh? Asked for more explanation as to why the EmDrive Thruster works, the report explains, “it just does.” The EmDrive concept is simple. Send microwaves into a conical design (think dunce cap). The microwaves will bounce around and there’ll be a net thrust. Except, that violates the laws of physics. You can’t have a force (thrust) without an equal and opposite force. Microwaves have no mass.
How can this be? Now, there are some theories floating around, as scientists are not exactly the type to let unanswered scientific questions lying around. As best I can tell, the leading theory suggests it works by, “creating a virtual plasma toroid that could realize net thrust using magnetohydrodynamic forces acting upon quantum vacuum fluctuations.” Well, that’s a mouthful.
Here’s what I think. The microwaves, traveling at the speed of light back and forth within the toroid, cause a warp of space-time. This warp ends up with an appearance of thrust. But it’s space that’s moving, not the engine. Aerospace engineer Roger Shawyer suggests it’s radiation pressure from the different space-time references being generated. Maybe so, but I’m wondering if some kind of test can be designed to measure the bend of space when the EmDrive is powered up. Maybe this is the first step to the warp drives we see in moves like Star Trek and Star Wars.
