A stimulating discussion with +Bill Gates on energy innovation. I was impressed with both the breadth and depth of his knowledge on these matters (he is obviously very motivated in helping to solve the Energy Crisis), though he obviously prefers to talk about his venture +TerraPower over molten salt reactors and thorium.

For those interested, TerraPower wishes to build a form of fast breeder reactor known as the Travelling Wave Reactor: http://en.wikipedia.org/wiki/Traveling_wave_reactor
