Economics of Space Mining

When humanity reaches out into the stars, the question is how will we get to them? According to the discussions on why alien life has yet to contact us, one theory is that Intersolar travel is so difficult and uneconomical that nobody has ever tried it.

 

The most promising and immediately available approach to raveling long distances through the tars is warp travel, the ide hat concentration of energy can bend space as per the general theory of relativity and cause a siopao move faster than the universal speed limit – the speed of light, “tricking” the laws of physics. This, however, requires an enormous amount of energy.

 

Intersolar travel, therefore, is a stage of civilization which can only occur in the event of virtually free, massive, unlimited amounts of energy. Just where is this energy to be found?

 

Attempts to develop cold fusion have yet to be successful. Using modern technologies, the most sustainable approach would appear to be an approach by Michio Kaku: the idea of self-replicating solar robots. Has ambitious as the project sounds, and as rightly far-fetched das it would be, the concept has immense power. Not requiring minerals or fuels on earth, robots powered by a mix of fossil fuel resources and combustibles on other planets like the methane on Titan, combined with solar-charged ion thrusters, would be able to efficiently mien the moon and other locales, creating solar arrays in space that would generate immense amounts of energy.

 

This argent about the inevitable economics of space also poses a reason that an alien civilization has not reached us yet. The economics of the future, in Kaku’s words, are the economics of energy, not the economics of minerals and fossil fields. Planetary resources, he says, are less important to more advanced civilizations than are the resources of the suns – barren systems, with no indigenous populations to worry about – are arguably better locales to mine and create solar arrays in than are live systems.
