It sounds impossible, but I've read the abstract of this article which claims to provide a cryptographic proof of a physical object (nuclear warhead): https://www.pnas.org/content/113/31/8618 https://www.pnas.org/content/113/31/8618 I'm not sure if this is possible to extrapolate to prove an energy generation process... But, it's exciting that a physical material can be cryptographically proven over a network (if I'm reading this abstract correctly).
