The EmDrive is extremely interesting: a truncated metal cone that, when resonating with microwaves, moves slightly towards its narrow end. This anomaly was first observed by Shawyer (2008) and later reproduced by Juan et al. (2012) in China, and recently by NASA's Brady et al. (2014). The Emdrive is still uncertain because it hasn't been tested in a vacuum yet (now it has), so it is probably wise to stay well away for now. Nevertheless, I got interested because I'm always looking for lab tests of MiHsC, and I've found that MiHsC can predict it quite well if you assume that photons have inertial mass and the metal cavity forms an information horizon. I've just published my findings in the open access journal 'Progress in Physics', here. Comments welcome.
