Concentrated Solar Power 12 Miles above the Earth

How to keep hydrogen in the thing up there. It is almost impossible to totally stop H2 leaks - the molecule is so small it finds its way through about anything.

Up there you have a constant barrage of bits of junk and incoming from asteroids etc.

How to fold up that monster for high wind events would be a bit of a problem.

This would be the understatement of the year.

Maybe?

This could be done, but at a huge undertaking. At 63,000 feet up there wouldn't any weather affecting the thing, only a few thousand feet up the cable. I am sure they can come up with something better than steel cable to teather the thing like maybe some sort of kevlar? Hydrogen is no problem as it is made from natural gas, as where I work we use over 70,000,000 cubic feet of hydrogen a day. Also oxygen is not much of a problem at the altitude.
Maybe NASA could do it since the shuttle is no more!.... lol
