Politcally Incorrect Musings
In space, no one can hear you cheer

While I was peacefully and quietly going about my life, the Universe did a paradigm shift.

The device tested by NASA was not efficient but was intended to only demonstrate a principle. NASA does not even appear to know how it works. Mind you, this will not produce enough thrust to leave the planet, but it would be very useful for orbital correction or deep space missions.

Every rocket engine design to date has been a reaction engine: fuel in, exhaust out. This engine, seemingly against the known laws of physics, has removed the penalties associated with those two things.

The questions of "why does it work" and "can it be scaled up" need to be answered, now.

Go build your own

This is not an effective thruster for spacecraft. The force equations are over simplified and do not take into account all of the operational boundary conditions which also flaw the conclusions of the experiments and test results. This thruster is an antenna. If this was a feasible method of propulsion or attitude control thruster the reaction would have been observed as a control error correlated to the high power down links on current satellites because this thruster is similar to a microwave tranismision horn. These control errors have not been observed. Even a very minut amount of thrust would bias the control system in zero gravity and cause an error. A reaction force would be generated at the back of the horn. The power to thrust ratio makes this very difficult to scail. Also the large amount of heat generation makes it impractical . The apparent thrust observed May be a component of the fluid flow of the chamber coolant or other un identified interactions of the B and H fields. Because this "thruster" does not operate in a classical way the test apparatus is more complicated to account for all potential interactions with its operating environment. The money spent on this would be better spent on Vasmer ion drives. But even Vasmer will require nuclar power to be effective for deep space maned missions.
