Sorry to come across as grumpy. It wasn't really the venue or topic to argue about exotic propulsion. There are many excellent resources online explaining why EM cavities are reactionless. You can write down the Poynting vector and then use Green's theorem, it's a neat result. With dire consequences for wish-powered spacecraft. -C

Don't be sorry. We need scientists to be skeptics when it comes to absurd assertions which violate the most fundamental principles of physics.

Extraordinary claims require extraordinary evidence.

There's actually a difference between being skeptical and calling this thing -- with peer-reviewed research[0] -- "wish-powered".
