Marathon Fusion, based in San Francisco, proposes a fusion reactor concept where fast neutrons from a 1.5 gigawatt thermal tokamak transmute mercury-198 into stable gold-197. The layered reactor blanket includes mercury and lithium near the core, surrounded by molten lithium-beryllium-fluoride salts. According to simulation results, the setup could generate up to 3000 kg of gold annually, with
