“The microwave cavity thruster as set-up by Tajmar continues to violate momentum conservation and thus does not work as advertised,” says Eric W. Davis, a Senior Research Physicist at the Institute for Advanced Studies at Austin.
What hogwash. Sure, it appears to be in violation of conservation of momentum, but if it works experimentally, then obviously that is not an impediment. Perhaps the law is not actually violated somehow, or the law is not as inviolable as we suspected (if the device works).
It may be a ‘quantum’ device. If so, then the Newtonian Laws go out the window..................
