Bill Gates tackles climate change

Nuclear waste fed into a terrapower reactor would potentially burn for decades before being exhausted, unfortunately, researching and testing terrapower will cost hundreds of millions of dollars, with the building of a test reactor likely to cost in the billions.

Gates dismissed climate change sceptics, saying terrapower would render arguments moot because the energy produced would be cheaper than pollution-spewing methods used today. Work on terrapower has been done in France and Japan, and there has been interest in India, Russia, China and the United States.

Bill Gates is backing development of "terrapower" reactors that could be fuelled by nuclear waste from disposal facilities or generated by today's power plants
