An anonymous reader writes "Microsoft founder Bill Gates has pledged to develop with Korea a revolutionary nuclear reactor that will leave far less radioactive waste than existing ones. Gates invested US$35 million in a nuclear-power venture company TerraPower in 2010. TerraPower is led by John Gilleland. It was formed from an effort initiated in 2007 by Nathan Myhrvold's company, Intellectual Ventures. The company includes expert staff and individual consultants who have worked for some of the most prestigious nuclear laboratories and engineering companies in the world." You may remember that Gates worked with China to build a reactor late last year.
