Asteroid mining

I have been working on three articles recently.  There is a JBIS article on a
500,000 ton per year to GEO Skylon/laser concept, one on power
satellite design considerations and this one on mining asteroids.  The
last one reached "draft for review" first and I hung a wikified draft
of it here:

I might leave it there since I don't know where it could be published.

It's too heavy on technical details, economics, extractive metalergy
for most venues.
