John Batchelor and I welcomed Dr. Mike McCulloch from the UK to Hotel Mars for a double segment to discuss EmDrive in light of the recently published and peer reviewed paper in the AIAA Journal of Propulsion. Our guest first explained EmDrive, then explained what was tested and published in the reviewed article. Mike also put forth his theory on why EmDrive works. Our guest refuted the dark matter theory, then we talked about being able to scale up the drive for spaceflight. Mike suggested it was not about a larger EmDrive. Rather, one might use many such EmDrives but make the cone with super conducting materials using Dielectrics to make the microwaves bounce around within the cone faster and faster. This would produce more energy (thrust). Don't miss how our guest explained this. Toward the end of the short segment, we learned about different attempts to get an EmDrive to space to test it in a vacuum. He said the big challenge was to understand it because it does seem to violate the laws of physics, especially the conservation of momentum law.
