NASA Cannae Drive and EMDrive propellantless propulsion were not the result of a thermal error

Paul March is one of the NASA researchers who did the work on the EMdrive, Q drive and Woodward Mach effect propulsion. Paul has some comments about how they did not make a simple thermal error in discussion at Talk Polywell.

Most of the observed forces in the Eagleworks Lab frustum devices were prompt with the same rise and fall times as our electrostatically derived calibration forces and therefore are not thermal in origins. That’s not to say we didn’t see thermal effects, especially with input RF power levels greater than ~35W, but the thermal effects with these large copper plus dielectric test articles, (2.5 to 5.0kg), always take tens of seconds to develop and are easily distinguished from the prompt E and M or more interesting force inputs since they always exhibit exponential rise and fall times.

BTW, the copper frustum’s temperature never rose more than 1.0 degree F. when using the above average power levels and test articles.
