From: Daniel Rocha Pay attention at this: " Experiments directly confirm for the first time that this behavior continues beyond the conventional limit of unity electrical-to-optical power conversion efficiency." It is above the conventional, not that it produces energy out of nothing. This is just a way of saying that it exceeded expectation of light emission for a LED.
Yes of course - these guys have to protect tenured positions at MIT, so they would never mention ZPE nor any of the other possibilities that we like to toss around here ... ... as Mel Brooks would say "we must protect our phony baloney jobs"
