Perhaps they have made the required measurements properly. The magnitude of the force is quite low and subject to error somewhat like the neutrino problem that CERN recently encountered. If they had the entire system enclosed within the drive mechanism, including all of the DC batteries and RF power generation then they might have something important. It will also be necessary that they ensure that very little RF or magnetic coupling can escape the enclosure by using excellent shielding.
I have to wonder how they could separate the power source from the device? Surely anything besides a self contained source has potential to cause measurement errors that can be subtle. Something as simple as heat distribution upon the surface might be adequate to generate lift forces. It is too bad that the device did not generate enough thrust to lift from the ground by itself which would eliminate many possible issues. I will be thrilled to learn that this space drive is real but remain highly skeptical.

My guess is that the thrust will be shown to be an error once everything is taken into account. The power to generate the large amount of RF must enter the device from somewhere and that is likely the root of the thrust.
