“炼金术”成真了？这家公司宣称：用核聚变“点汞成金”，未来每发电1千兆瓦或产5吨黄金

Core Viewpoint - Marathon Fusion claims to have developed a method to convert mercury into gold using nuclear fusion, potentially doubling revenue for fusion power plants [1][5]. Group 1: Technology Overview - The technology is based on existing fusion principles, utilizing high-energy neutrons to convert mercury-198 into mercury-197, which decays into stable gold-197 [2]. - The process does not reduce the power output or tritium breeding capabilities of the fusion plant [3]. Group 2: Commercial Potential - Each gigawatt of fusion power capacity is estimated to produce gold worth approximately equal to its electricity revenue, potentially doubling the plant's income [5]. - The global annual gold production is around 3,500 tons, and the company believes the gold produced from fusion can be absorbed by the market without affecting gold prices [6]. Group 3: Challenges and Considerations - The main challenge is the potential radioactivity of the produced gold due to the presence of other mercury isotopes, requiring a storage period of 14 to 18 years for safety [9]. - While particle accelerators have previously synthesized gold, the yield has been minimal and costly [9]. - The technology could also be applied to produce other precious metals, but gold is seen as the most viable option due to market size [10]. Group 4: Industry Context - The commercialization of nuclear fusion still faces significant technical challenges, with no fusion experiment yet producing more energy than consumed, although private investment is increasing optimism in the field [11].
