I’ll tell you what makes sense—your use of the word “if”. “If” it works, then it means our understanding of physics is fundamentally flawed. So fundamentally, in fact, that we’ll have to start over again all the way back from the dark ages. I don’t think that’s the case. Like I said and will continue saying, I need to see it work for myself. No more of this “he said she said” stuff.
You sound like a Y2K bug conspiracy theorist and climate alarmist rolled into one.
This sort of thing went on all throughout the renaissance. Relativity meant that Newtonian mechanics was incomplete, not fatally flawed. If this thing winds up working, it isn't free energy, it is a way to directly convert electrical energy into kinetic energy.
This effort to treat the laws of physics like holy scripture is counterproductive. This is probably why scientific progress has become stagnant. We spend our time on fairy tales like global warming (and a couple of others that even mentioning would guarantee a long and acrimonious thread) rather than real, observable science.
As soon as something interesting is observed, the first impulse is always to discount it rather than truly addressing it. Science anymore amounts to mostly defending orthodoxy. Galileo would be persecuted and rejected by contemporary scientists if he made similar sorts of unorthodox observations today, as has happened to many other real scientists who have done nothing more than report what they saw. Most "scientists" today should dress in robes and wear funny hats, it better fits their frame of mind.
