[ExI] pentagon wants orbiting solar power stations

What of the possibility of autonomous and tele-operated robotic mining  
of near-earth asteroids and space manufacture of some of the larger  
solar sat components?  If possible it would help avoid having to drag  
so much out of the gravity well.   Not to mention that extraction of  
bullion (!), metals and combustibles is space could generally greatly  
enhance space opportunities.    I heard about such things ages ago but  
haven't seen a lot since.
