Comment Cheap way of mining asteroids. (Score 1) 569
Just send self-replicating miner robot to asteroid belt, with enough raw materials to start operations there. Then just wait couple of decades and go fetch piles of processed minerals back.
Resource cost is minimal as building and sending one robot is enough. Hard part is designing such robot, but it shouldn't be impossible even in the near future.
