Very funny, as usual for these 'inventions'. Note the usual distinct underkill in the application proposals:
David has several ideas for how this technology could be utilized. One possibility is that it could be used to power appliances directly. A small input could produce an output large enough to power an air conditioner, refrigerator, etc. Another possibility is connecting one of these devices between the power line and your home. If the output of one of these devices could be scaled up (or more than one of them utilized) you could power your home while consuming little if any real power. Finally, he imagines a setup where these devices could be built, used to power your home, but the excess could be sold back to the power company.
Hellooo, man! Let it power itself, build a huge device and wipe out all competition in the international power market. Now laugh all the way to the bank.
.....
Seriously, his explanation is fundamentally flawed. The back EMF does not govern the primary current of a transformer the way he claims, but through self-induction. If there is no load on the secondary, the magnet field built in each half-period inducts a back-EMF in the primary coil, and this reduces the current (ideally to zero). However, when you load the secondary, it taps some of the energy that would have produced the back EMF, and thus reduces it, making the primary current rise accordingly.
In the ideal transformer, this means that the same amount of energy tapped from the secondary has to be fed to the primary. In a real transformer, you need to add losses.
So what is happening for this fellow? Well two possibilities:
1) It is a scam. He knows it doesn't work and is simply rigging the figures in hopes of gaining fame and/or money.
2) He really thinks it works. In this case, he is probably being fooled by phase-shift. Building an true AC power meter is not simple, so most manufacturers use constructions that work on derived values. Such derivals assume that the current and voltage are reasonably in phase. However, big, strange coil constructions are VERY likely to cause huge phase shifts, causing his power meters to produce strange readings.
