Assuming em drive propulsion is a real phenomenon...assuming....you should be able to instantly propell your microwave oven into orbit after unplugging it.
My new understanding of light and the spectrum of light as being pure code and not transmitting energy nor mass perfectly supports the observation that seem to say an em drive engine is possible. That's because you create and send a photon to transmit information which we all know are the "wavelength / frequency" for each. at opposite ends of the spectrum you should then have pure wavelength with no frequency and pure frequency with no wavelength at the other end of the spectrum. What is pure frequency? what is pure wavelength. these are both properties expressed as analogies. at one end of the spectrum I would guess you have pure acceleration and at the other negative acceleration ? the basic positive photon just finds energy of existing momentum of mater and subatomic particles and deploys it. It becomes a frames of reference mater when a gamma ray seems to activate a sub atomic particle when it really is just deactivating it essentially slowing it down rela
