The verification was complete crap, as outlined in the review article. See the “power magic” image. Even that image over-thinks it. Rossi’s marks used AC clamp meters that will incorrectly measure power consumption if you connect a diode in series with your load (and Rossi had a circuit generating “trade secret waveform” there).
edit: actually, the manufacturer’s page for the meter they used is not very clear on how the clamps work, and I can’t be bothered to look deeper for Rossi’s sake. There’s two types of clamps, DC or universal clamps use hall effect sensor, AC clamps use a pick up coil and measure only the AC component. The only thing that could not be fooled is high bandwidth oscilloscopes connected via shunts to every conductor going into this device, integrating the current*voltage.
Other issues: 2000W from <1 gram of loose powder is a little odd, to put it mildly (its not easy to conduct that much power away from something small). And of course, someone with a legitimate, working device that produces heat would invest into a variation that does not need external energy input to heat any resistors (and the concept is truly ridiculous).
On the other hand, the reviewers may well be honest, because if they weren’t honest they’d have told us they did the whole thing with oscilloscopes and such.
