Story summary

Marathon Fusion, an ambitious Silicon Valley startup, is stirring excitement with its bold claim of transforming mercury into gold through nuclear fusion. By bombarding mercury-198 with neutrons, they envision producing a staggering 5,000 kilograms of gold each year per gigawatt of fusion energy. However, this groundbreaking method is still in the theoretical stage and must overcome major technical hurdles before it can become a reality.

History

Historical Context

In 1940, scientists at the University of California, Berkeley, created plutonium, marking a significant advancement in nuclear science linked to the Manhattan Project. This achievement paved the way for future innovations, including attempts to transmute mercury into gold, a concept rooted in alchemy. If successful, such transformations could revolutionize resource production and reshape economic views on precious metals.
