RE: TIL That NASA EM Drive Engine Does In Fact Works - We Can Go To Moon In 4 Hours And To Mars In 70 Days
well, the concept in terms of physics is amazing. The issue I see is that you need a kilowatt to get millinewtons...so I suspect you need to cool the engine to get rid of the horrible loss. In term of efficiency, seems...well... subprime.
In space is relatively cold, I heard, so that won't be a problem. Also, less friction should help.
True, but the concept of "temperature" among vacuum is pretty weird. I wonder if the heat can go away with no artificial cooling. To cool while in the vacuum is not as easy as it seems, since vacuum is a very good insulator.
The heat is directly induced into the magnetron coil, if this is the EM drive I know of https://en.wikipedia.org/wiki/RF_resonant_cavity_thruster
I have a theory that impulse is caused by nano-chaotic electron motion. This device demonstrates this could be correct. Assuming it is the same device. Recently also they discovered that electrostatic repulsion devices, based on capacitance, that previously had been developed to create impulse by repelling argon atoms or similar, could produce a usable amount of impulse without any gas at all. If it is an EM drive it also includes a resonant cavity, and I believe that the secret to making this device work is tuning the resonance to cause maximum nonlinearity and amplify frequency components beyond the frequency of cosmic rays. Which is why I think a tesla coil should be the emitter, not a magnetron.
