James Cameron just wants to be that cool guy with a bunch of money throwing things around. Its great that he did the submarine thing. But I would expect that the cost of developing space based mining would cost into the trillions of dollars, and you would warp the world market for precious metals if you ever figured it out to the point where you would never get your investment back.

Beyond that, the whole fuel depot in space, shouldn't the goal be to get away from using heavy volatile toxic fuels to get into space, there has to be more research into non conventional systems, like nuclear and Ion and pulse engines.

We should be focusing on more efficent long lasting clean propulsion, we should be looking into the abilitiy to assemble space craft in orbit to get around the difficulties of gravity.
