Gravity storage is not a heat engine, ergo Carnot's rule does not apply.

But the second law of thermodynamics still does. Gravity wells are still a mechanical system, just not a heat engine.

>Not even close. Second law of thermodynamics puts a limit on heat engine. Gravity storage is not subject to such limit.

Emphasis mine. Don't be a pedant.

Well, my important point was that hydrocarbons are fucking terrible but keep focusing on the first part.

Laws of thermodynamics apply to the entire universe, ergo i dont think anyone is claiming to break laws of physics

2nd law of t only applies to mass. Gravity works via gravitons which are massless so the 2nd does not apply..
