That could very well be real. What I find somewhat odd though is the sound. Makes me wonder if there isn't some hidden pulsing device associated with it somehow. This is a fairly common trick and is easily hidden in smaller, low-mass devices.
Whats your opinion about the one in post #6 by Rav...Emu. Real or fake, Plausible ? If it real it should be able to pump water.
The number one thing to look for in devices like these are asymmetry or broken symmetry as Tom Bearden calls it. If you can't spot any such thing, it's almost certainly a hoax. Usually asymmetry shows itself as two or more kinematic equations linked together with dead-spots or non-linear transitions between them. These transitions must react differently going one way versus the other. That is what creates the out-of-balance condition whereby you have the potential to harness energy from the vacuum.
It takes some time and experience to recognize hoaxes and I get tripped-up routinely and need a second pair of eyes to look at it. Your best chance of discovering the trick is to imagine yourself given the task to replicate the video--not create free energy, just replicate what you see and think about how your would do it. More times than not, you'll walk right into what was actually done to fool the viewer. If you ever run into a video where you just can't figure out a way to visually reproduce it. That's one you might want to spend a little more time on, because it could be real. The sad thing in all this is I'm certain I have dismissed a video or two that was real, but I could see how it could have been faked. There really are inventors out there that might show somebody what they did and that somebody posted it to YouTube having no real idea what it was or how it worked. I say keep an open mind and let these things just flow in. Hopefully sometime, late at night, everything will come together in your minds eye and you'll see the solution clear as day. That's when you get up and write everything down, maybe even post it here first.
