Atmospheric mining links

[Drashner1]

Yuppers - a sufficiently powered orbital ring would let you drop skyhooks down into the atmosphere - even on a gas giant probably - and just pump atmosphere into space where it could be compressed, packaged, and launched elsewhere using the ring. As long as you kept feed energy into the ring, you could keep this up more or less indefinitely (although I suppose if you sucked up the entire planet that would put a dent in your operations).
