Took a quick look at their website. Like most of these types of operations, they're trying to attract investors without ever demonstrating a practical application of their "technology".
As a practicing electrical engineer, I find their description of how it works full of "techno-babble" intended to impress lay people, but meaningless to anyone who actually understands technology.
I couldn't find a manual on line for the wattmeters they claim to be using, but I have a rather strong suspicion that the machine "makes" power by fooling the wattmeters.
The input wattmeter would be measuring low duty cycle pulsed DC, and I'd be willing to bet that the RMS function can't follow that waveform. Things like pulsed DC can easily fool a digital meter, particularly when the pulse rate is something close to the sampling rate of the digital meter. Same reason that digital meters don't work very well for measuring noisy signals on engines.
If they replace the digital wattmeters with true analog meters (which mechanically integrate the waveforms), or even better, with a calorimeter arrangement, then I might believe the results.
Until then, they're just another bunch of charlatans preying on a gullible public.

Today's Featured Article - Product Review: JB Weld - by Staff. JB Weld is basically an epoxy glue that does an exceptionally good job of bonding to cast iron and steel along with several other materials. As I mentioned, it is so common that I have yet to buy a tractor that did not have JB Weld used somewhere. It is sometimes used so well you can't tell its there and other times used as a sloppy quick fix. Finding where and how it can be used correctly is key to whether you are using it as an "inelegant hack" or an integral solution to difficult and expens
