Ensure any replies are tagged [OT] PLEASE. If posting this sort of material please put it in [OT]:, if anywhere. And, if you post a link to a video it would be a very good idea to write at least a few sentences telling people what it is about and why it is worth watching. AND if the video is not in English you should say what language it is in and definitely should write a few sentences telling people about it. This video runs a very very very good chance of being about "perpetual motion" machines and sources iof energy which have no scientific basis. As such they will get a very very rough ride from people on this list. They are not really the sort of thing that is liable to be useful here. Anytime you PERSONALLY have a working model that we can test, put it in EE, tell us about it, and we'll be on the next plane to come and help test it :-).
