Over-unity

Biological systems seem to defy the second law of thermodynamics but they say there are always hidden costs that set us backwards. They say it isn’t possible, even though some have shown it is. True, they put their work in a black box, but that’s because if they revealed their science, then the big corporations would copy it and give them no credit. If you discovered the secret to living forever, would you give it away? Would you try to sell it to a disbelieving world? Or would you keep it a secret for only you and your wealthy friends to use?
