Cannae is launching a Cubesat containing his drive design, possibly within 6 months. link
That's pretty much the ultimate test. (Yeah, long time, no see. Just dropped by with this tidbit. Will be back again, when circumstances favor longer involvement.) |

I'm no scientist but I know what I like and THAT is just freaking cool…if it works! |

It would be amazing if it works. |

It's hocus pocus. Even if it "works" the energy required to do anything practical with it is outrageous. |

Have to agree with Winston. The energy requirements for this thing are ridiculous. And never mind that it violates the basic foundations of physics. |

I've been thinking over the conservation of momentum question, and I suspect that perhaps, though it appears to act like a rocket, perhaps it's more analogous to a ramjet? Just as a ramjet throws superheated air out the back to produce thrust, the EM drive takes the vacuum energy particles of the Universe and impells these out the rear of the "nozzle," generating thrust in the opposite direction. So there actually is a propellant, and it's not breaking any law of physics at all. Just a stab in the dark of space, as it were… |

Well, this beats an endless debate among scientists down here on Earth. Put it in space and if it works, it works. |

Photons, though massless, have momentum. If the EM drive is expelling photons in a nearly uniform direction because of the applied EM field within it, conservation of momentum actually requires an equal and opposite reaction. |
