No, it's not like the Kinetica demo. There's a big difrerence: in the more than two years since that fiasco, Sean has learnt something: Orbo will run longer if it's attached to a battery!
If you go to the official Steorn website, you can read/hear all about it. In a promotional video, Sean explains that Orbo is attached to a battery but he claims that it's constantly recharging that battery. So we see a thing spinning (doesn't seem to be actually doing any work) attached to a battery. How long can you keep a flywheel spinning on low-friction bearings with a single battery? Days? Weeks? How easy is it to have the live demo off-line for just the time it takes to change the battery?
