A direct conversion of thermal energy into electric energy would cool down the entire system. Since electric energy carries no entropy, this would reduce the overall entropy of the system. This is forbidden by the second law of thermodynamics.

- gus_massa 5y agoThe "system" is the circuit (including the graphene), a closed box around it and the gas that is inside the box.
- Rury 5y agoIf treated as a closed system, the claim would indeed be violating the second law of thermodynamics. If it's treated as an open system, then well yeah... the "limitless" energy is actually coming from outside the boundaries of the system, which they conveniently neglect to track. No magic to be had here, but a cool way to convert energy...
