I can't really give any specific information on it other than from what I saw. If anyone has traveled on Singapore airlines before, you'll know what I mean when I talk about the "in seat tv" that they have. In fact, they probably have it on other airlines by now, But I don't know since I haven't traveled on them. On these headrest TV screens, you have a wide selection of tv shows/movies/documentaries etc you can watch. This one I saw roughly 3 years ago on a trip, and it was a Documentary about "free energy". Now, I've tried looking for it, and downloaded what turned out to be a conspiracy theorist one, which is not it. What I can say was: .It was by some science show (in the US), as I thought it was the discovery channel, but it could be some other cable TV network. . It was done properly. It had an engineer debunk or review each "free energy" apparatus and explain why it couldn't work. . The Engineer had brown hair (Yes, I can't remember the name of the film that much!) If anyone has seen the same one, could they tell me the title? I can remember one of the people who built a machine was a Frenchman, and it was like a giant ferris wheel, if that helps.
