I have speculated previously that the EM drive is a form of Puthoff vacuum engineering and Sawyers' claim that it is based on SR is in agreement with my relativistic interpretation of Casimir effect which casts fractional hydrogen as Lorentzian contractions. I am suggesting the focused microwave fields inside the EM device can oppose large virtual particle pairs similar to Casimir effect and opposite the Paradox twins where the wavelengths instead get longer from our perspective as the remote twin approaches C. The obvious test here is to marry the experiments, I think the EM drive would benefit from hydrogen loading and a sputtered inner coat of Ni tubules - perhaps an additional Ni plated probe extending inward from the small end along the axis of thrust for maximum linkage to the focused microwaves -like an antenna feed except the intention is to push fractional hydrogen along the axis - if I am correct f/h2 opposes motion between fractional values and this has a vector that is 90 degrees to 3 space [the relativistic connection/Lorentzian contraction] - any Pythagorean opposition to an axis 90 degrees displaced can result in propelantless drive at the expense of time dilation..something gets older or colder. Likewise we should be able to design a reactor that is also a tapered microwave cavity and utilize the EM tech as another form of controlling the reaction - I can imagine Rossi's resistor dropped down on the short end to remain parallel to the new tapered reactor to keep heating evenly distributed while also using a microwave feed as an additional control mechanism to quickly add and subtract energy from the reaction. I know Jones could offer some microwave frequencies that would be likely to interact better with the environment.

The latest research comes from a team headed by Yang Juan, Professor of Propulsion Theory and Engineering of Aeronautics and Astronautics at the Northwestern Polytechnic University in Xi'an. Titled "Net thrust measurement of propellantless microwave thruster," it was published last year in the academic journal Acta Physica Sinica, now translated into English. ...
