“We found out that the cause of the ‘thrust’ was a thermal effect. For our tests, we used NASAs EmDrive configuration from White et al. (which was used at the Eagleworks laboratories, because it is best documented and the results were published in the ‘Journal of Propulsion and Power’.
With the aid of a new measuring scale structure and different suspension points of the same engine, we were able to reproduce apparent thrust forces similar to those measured by the NASA-team, but also to make them disappear by means of a point suspension."
