So why do I support this? Here's why, otherwise I wouldn't be blogging about it
Bingham-Cooper Mine |
- Many minerals, such as gold, tungsten, platinum, palladium came to earth from asteroids
- Asteroids contain many minerals and elements that are scarce, or hard to get to on earth.
- Instead of strip mining an entire mountain, creating pits in the earth, as shown to the right, we can use an entire asteroid.
- Technology will need to advance in many realms in order to harvest an asteroid. Everything from power generation, rocket travel, vacuum machinery will need to take enormous strides
- Energy, specifically high power density technologies will advance, generating higher power density devices that will have wide ranging benefits on earth. It isn't practical to use gasoline as your fuel source with a launch cost of ~$3,000-$6,000/lb
- Reduced pollution from the energy intensive methods of mining and resource recovery on earth. Rare Earths aren't rare by definition, just making their recovery economical is. Both the cost of recovery per pound and energy usage per pound is very high making them both incredibly useful, and incredibly bad for the environment.
