>A vehicle equipped with it still has to generate energy. Yes, with solar panels. No mass is expelled, which is why there's so many claims about it violating the law of Conservation of Moment. > Going by these experiments the EmDrive doesn't have a hope of ever matching the mass efficiency of an ion drive. If the craft runs out of ions to throw really fast behind it, how could it get more? Well, it can't. That's why the EmDrive is a paradigm shift; solar panels allow for the generation of electricity, which then powers a magnetron to create thrust. And efficiency? Well, ion drives presumably have decades of head-start. Give it time.
