That is also the physics that I learned but I have been reading about this for the last couple of years and it works, it happens. That is hard to argue against.
I’m not saying that the results the scientists are observing are not real, I’m saying that extra energy maybe coming from someplace else to account for the output over input.
Sorry, I could be more cogent but I am already two martinis into my lunch. ;). Jesus drank wine but I drink vodka.
Wine is the blood of Christ but vodka is the spirit of God (I think that I am going to hell...)
