Of course your physics professor (and their books) definitely knows everything in the world without needing to venture outside or do any real world experiments. And they certainly couldn't be a fragilista[1] nor could they possibly have God Complex[2].
Seeing as your professor is all knowing, maybe they could finally tell us all how lithium polymer batteries work [3]?
Thanks for the links. We have some Profs who have a God Complex, but he's just the typical nice Physics Nerd. He didn't proof that it doesn't work and urged interest in it, if somebody finds out more. But he couldn't find out a way that this phenomenon was real. That doesn't mean that phenomenons like the on in the article are impossible, but that the setup to create such phenomenon is probably wrong or not documented well enough to come to a better conclusion than - "it's definitely wrong".
There is a huge difference between believing that energy conservation is wrong and believing that there could be unexplored avenues in the technological application of electrostatic forces.
I'm not a cold fusion zealot but I don't think it's correct to say that it would violate energy conservation, since they are talking about nuclear reactions converting mass to energy, just like fission and fusion. It's just that they're talking about unusual reactions that most scientists think are implausible.
