I'm still interested in why they are so focused on building such a tiny proto type. Usually one would start out with a model that you can work with and easily get parts for, the scale it up or down as needed. The videos I saw on the web were crappy at 56k, but doen't remember seeing it make a complete revolution without Mr. Hand pushing or tweeking on something.
From the interview linked above, he states the next demo will be purely web based, sort of a video chat room. Veiwers can ask questions, and the operators will demonstrate (if they can). Imagine there will be more technical problems, and there will be more talk then motion.
I wonder if magnets can be manufactured with a precise and predictable strength, or need to be sorted after they are made?
