Hang on though, there's always the "Trade Secret" route of things, instead of the "I have a patent now" way of doing business. If someone came up with a way of generating energy over unity, I'd be willing to bet they'd opt for Trade Secret and keep things under very tight wraps. Once it is patented, too much info is available to other people to try and come up with a competing product.
But of course you can't get more energy out of something that you put into it. Even less so if it is doing work.
You can't win, you can't break even, you can't even quit the game. One of my favorite quotes.
Whatever they have might be slightly more efficient, might or might not be revolutionary, probably is just trying to get investment money.
As for all the over-unity claims elsewhere, I see no possible motivation for a company to invent a machine that produces free energy, and then to just bury it. It would at the very least, be MASSIVE short term profits, and what do CEOs like more than short term profits? Nothing at all.
Even if a CEO told their R&D department to bury it, they would need to murder the entire team as who wouldn't want to publish those findings and go down in history as the person who broke physics and unleashed a worldwide (hah I didn't say global) revolution that would literally change everything?
The idea that there are dozens of free energy devices collecting dust in company vaults is just nuts.
