February 2018, James Woodward loaned a good Mach Effect Thruster (accompanied by a specially designed isolation transformer) to Martin Tajmar at TU Dresden, Germany.
But for an unknown reason Tajmar and his team didn’t use the mandatory stepup/isolation transformer: Therefore they operated the device at the wrong frequency, one that could never trigger any thrust signature.
Even worse: as the Dresden team saw nothing conclusive, they increased the voltage for too long and the temperature in the PZT stacks, so they also managed to toast the initially good-working device before returning it to Woodward in California four months later.
Martin Tajmar previously had good results on an 18 year old test device he had received from Woodward.
