He thinks the company Planetary Resources is going to announce at that they will be mining asteroids. They have the money (James Cameron, Google), the science (Ex-NASA people,including engineers and astronauts). The first step would be setting up depots. That is mine the stuff and keep the materials in space for delivery in space. It is far cheaper to go get water from an asteroid and give it to a space station than it is to lift it out of Earth's gravity well."
