Marathon Fusion, founded in 2023, aims to transform mercury into gold using nuclear fusion technology, proposing a process that involves a tokamak and fast neutrons. Their unverified research suggests that a 1 GW reactor could produce up to 5,000 kg of gold annually, valued at around €582 million, though the gold would remain radioactive for up to 18 years. While the company has raised nearly €10 million and garnered positive expert feedback, the feasibility of their approach and its impact on tokamak operations remain uncertain.
