Video of Steorn CEO explaining why its perpetual motion device failed at demo

The poor guy is squirming, as you can see in the video below. I'm not going to say he's lying, but he's not very convincing either. It's a little suspicious that all six sets of bearings (two per machine) broke at the same time, and the two models not on display have been whisked off to who knows where. There is a lot of fluffy talk, along the lines of "not ruling out but not willing to commit", especially in reference to the promised release of videos and other material.
