Unfortunately Tesla died pauper. We will never know what he could have achieved had the world been a different place. But it wasn't and it isn't. Westinghouse beats the Teslas of the world every time. :(
what nature has provided for us.
Sunny my apologies for name-calling.
You are putting yourself outside the natural realm? I think that it might be an issue of perspective. No one is about to mine up all the moon and make it look like a ritz cracker with a bite out of it. We couldn't strip mine every asteroid and every planet and "ruin" them (how do you ruin a lifeless uninhabitable body?), if we tried, not in a thousand years. All of this boils down to strategies for a cleaner, more prosperous earth. Renewable energy on earth is uncertain, and also has problems. It is by no means a panacea. For instance, wind-farms are now known to kill certain types of birds, geothermal power is not worth its initial heavy outlay, and solar power does not work well in many climates.
Even for renewals space colonization offers perhaps a better option. Ffor instance, the concept of orbitting huge solar power generating satellites in space, which beam inexhaustable energy from the sun by laser (or maser) to collection stations on earth. This collection-tramission-recollection method has been tested in scale and does work. The stations could be assembled in orbit by workers and robots up there, perhaps using materials from the moon. Even if that was not the best way to go, there is still another option for getting things to orbit cleanly, one we might seen in our lifetimes if there is funding for it: a literal elevator into space. www.highliftsystems.com is one company working on a method for doing that. All these arguements tear down any radical environmentalist diatribe against space utilization. All that's left are some vaguely shamanistic beliefs that the heavenly bodies have souls.
