I don't understand your line of thinking at all. And I believe to know that you are not exactly unlikely to exceed my intellectual capabilities. Yet, sou seem very daft to me right now. Of course free energy is useless. Of course you need stable relations of energy exchange. Or call it equilibrium if you must (from my times with economics I came to resent this term).
What does this even - AT ALL - contribute to the discussion at hand? I am describing how a rock is not sentient and you are saying "Not really , you need x minerals for a rock to be rock and a dolphin won't at all be a rock".
Go figure.
