The Foresight Institute is concerned with nanotechnology, especially with advancing beneficial nanotechnology. They have organized their thoughts into Foresight Nanotechnology Challenges, including clean energy, clean water, health and longevity, preserving the environment, information technology access, and of course enabling space development. The Institute also offers the Feynman Prize in Nanotechnology. There are prizes for communication, government policy, and research that promotes beneficial nanotechnology. The ultimate prize, the Feynman Grand Prize, for $250,000, is for making a nanotech-sized robot arm that can manipulate atoms and molecules, and also a simple but extremely tiny computer (which I assume would need to be built with the nanotech assembler).
The chairman of the Foresight Institute's Prize Steering Committee is Peter Diamandis, also known for many space prize and space business activities.
