Bill Gates talks about Feynman physics lectures and mentions, among other things, his involvement with Nathan Myhrvold's Intellectual Ventures:

That's been really exciting to take this idea of gathering top scientists from a broad set of areas and think about problems that can be solved. And in the case of the foundation, you know, Nathan (Myhrvold) has used that ability to convene great scientists to look at things like how do you deliver vaccines without having to use as many refrigerators, or how do you pasteurize milk in a better way, some very interesting things. And then I also sit down with that group when they're looking at their rich world applications, including things around energy, and one of those has actually led to creating a company called TerraPower, which is focused on a new, very radically improved nuclear power plant design, which is a hard thing to get done, but extremely valuable if it comes through.
