Gorgias

So that would violate the law of energy conservation and the second law of thermodynamics? Lets use hydrogen as an example. lets say you pour water into an electrolysis machine to get hydrogen. The hydrogen is then used to heat a steam generator to create electricity. It would be correct to say that the above is an open system rather than an isolated system? How would I go about explaining to someone else that that idea is an open system and violates the law of energy conservation and the second law of thermodynamics IF that is violating both.

I hope this is in the right forum if not please forgive me for my ignorance. Is there a fuel that when used will create more energy than is required to create that fuel? As an example It takes 50 KWH to create one KG of this fuel. When you burn this fuel to heat a steam turbine generator the generator then creates more energy than it took to make the fuel? So then you could take this fuel to operate the steam generator which would it turn operate the machine to make more of this fuel plus excess? So the fuel cannot be wood or coal etc it is a man made fuel like gasoline or hydrogen etc. Is this possible or does it violate the law of energy conservation or perhaps some other law of science? Thanks for any help.

I am Gorgias the name is from a philosopher I respect. Glad to be here.
