Marathon Fusion Claims to Convert Mercury into Stable Gold Using Nuclear Transmutation
San Francisco startup Marathon Fusion claims to have converted mercury into stable gold using nuclear transmutation, reportedly achieving a production rate 10 times higher than CERN's 2025 record. The process involves fusion-generated neutrons converting mercury-198 into mercury-197, which decays into gold-197. While the company shared gamma-ray evidence, it has not disclosed the quantity of gold produced or detailed experimental data. Marathon Fusion also aims to produce medical isotopes and develop fusion reactor technology, though the commercial viability remains uncertain.
