Can Bill Gates Provide America's Next 800 Years of Electricity?

With a team of engineers, physicists and nuclear experts at the start-up TerraPower, Bill Gates and fellow billionaire Nathan Myhrvold are trying to develop "a new kind of nuclear reactor that would be fueled by today’s nuclear waste, supply all the electricity in the United States for the next 800 years and, possibly, cut the risk of nuclear weapons proliferation around the world," writes Matthew L. Wald.  

The complicated, and costly, process involves using uranium 238, the "mostly natural waste" produced by today's conventional nuclear reactors, and eliminates "several routes to weapons proliferation".

"The engineers working for Mr. Gates acknowledge the enormous challenges but say they are convinced that he, and they, are chasing the solution not only to energy and weapons proliferation but also to climate change and poverty," Wald adds.
