I have given decades of thought to this problem.  In the relatively
long run and following a trillion dollar a year power satellite
construction business, I can see mining and maybe manufacturing from
that mining to support the power satellite business.  The Mond process
is particularly useful in sorting out nickel-iron objects.  But the
plant size needed to make it economical is up in the 50,000 ton range,
and while automation is useful, it's also going to need some hundreds
of people to keep it running.

But perhaps you have ideas I missed.  Can you be specific about what
could be mined or manufactured in space and sent back to earth at a
profit?  I would also be very interested in your estimates of the mass
budget and the capital required.

Keith

PS.  I see no reply to the question of manufacturing the equipment
needed for 1000 GW scale reactors per year.
