On Reddit's Futurology area, JordanLeDoux explains what the EmDrive and Cannae Drive are, how they differ, and the controversy they are causing in the science community — a great read.
Following the positive results last year and early this year, Eagleworks have been able to dedicate more and better hardware to the experiment. They plan to conduct the experiment with more controls at higher power this year, and when they are able to achieve results higher than 100 micronewtons for either device, they plan on having the test replicated at the Glenn Research Center, the Jet Propulsion Lab, and John Hopkins University Applied Physics Lab.
If the experiment for either or both devices is replicated at higher power, and again at the other labs, it is likely that the physics community will work very hard to try and invalidate the experiments as there is little explanation for the results. This is good. This is science. You don't do science by proving correct things, you do science by disproving wrong things.
