Huemul Project Site

In the early 1950s, an Austrian scientist named Ronald Richter attempted to build the world's first fusion power plant on an island in a lake in the Andes, the undertaking being known as the Huemul Project. A couple of years and an equivalent of several hundred million US dollars later it came into light that Richter never had got any proof of his design actually functioning in the first place. As the patron of the project, President Juan Perón, was ousted in 1955, Richter was arrested for fraud. Today the ruins of the project can be visited on the island, and the city itself remains a center of Argentinian nuclear research.
