Lets give these guys a chance! If it's a bunch of bunk, then careful, sound science will tell us such. It is as much bad science to debunk an unconventional claim without examination, as it is to make one in the first place. Just because we think we know it all doesn't mean that we do!
Whatever is going on here (if anything), one thing we can be
sure of is that this has
nothing whatsoever to do with "perpetual motion", and I am sure the people involved are not making irresponsible and frankly
stupid claims along those lines.
The whole area (pseudoscience?) of "free energy" (for want of more appropriate terminology) is populated with charlatans and hoaxers. The link below is interesting though... especially since this Moray came up with solid state devices long before Shockley, Brattain and Bardeen introduced the transistor shortly after WW2.

Can anyone pour cold water on this one?
