Apparently there are some issues with this. “This is a direct indication of a thermal effect in reverse (heating versus cooling), which produces a clear false positive thrust signal,” says Davis. “Tajmar has to account for and reconcile this fact as well in his data analysis which he apparently did not discuss in his paper. This would be another nail in the coffin against the existence of any real definite momentum violating thrust produced in the microwave cavity.” Exciting if it's true, but it sounds more likely that they've made a bit of an error.What’s more, when looking at previous EMDrive experiments, Davis noticed that the alleged thrust was generated slowly, and not instantaneously, when the electrical power was switched on.
