This is an idea I had based on the Vacuum Vacuum.
Drop a tube down from space to earth, to use as a vacuum
cleaner, keep the ground end capped when not in use. To
reduce the weight of air in the tube (which would cancel
the vacuum) make it black so absorb sunlight, and
insulated on the outside,
so the air inside is warmed. For
use at night, heat the air going in. Or just suck with the
vacuum that's already there, it will recharge by heating
the next day.
One issue - having all your dust and rubbish raining down
onto the upper atmosphere might be bad.
Similar idea which inspired this, but not a chimney. [caspian, Oct 29 2018]
||You could put a filter bag on it like regular vacuum
cleaners sometimes have to stop the dust going
everywhere, but the astronauts might not like
having to stop at your vacuum cleaner to change
||Well, ignoring the standard difficulties with such a scheme,
you could solve the problem of needing astronauts to empty
the vacuum bag by putting the bag at ground level.
||Then you could have the astronauts at ground level too, and save the trouble and expense of a launch.
