There is a new plan out there that is as far fetching as it seems in reality as well as in its imagination. A group of tycoons are planning to mine asteroids for their valuable minerals. They plan to catch asteroids and squeeze them dry of their metals which will then be sent back to earth.
The plan is futuristic but some believe the technical difficulties can be overcome. The plan has large start-up costs and will take many years before it happens but it may well work.
