Building on Grognard's MA Beanstalk

Joesph over on Greyhawk Grognard has an interesting idea for an alternative setting for Metamorphosis Alpha/Gamma World. Basically take a space elevator and attach a bunch of StarLost/Silent Running style eco-domes in high orbit. I think the idea can be taken further for a variety of adventuring possibilities.

You still have your domes. However beyond geosynchronous orbit lies a asteroid that is the counterweight.

You several option with this asteroid. You can opt to populate it with levels creating a mega dungeon that you climb UP to. A crazy dungeon in the spirit of Barrier Peaks or Anomalous Subsurface Environment. Or you can have it essentially hollow with a hollow world environment.

You can have more domes spaced along the beanstalk each with their own levels of gravity until you reach zero G at geosynchronous orbit.  As for the counterweight asteroid note that the "deeper/higher" you go the heavier the gravity becomes. Something to add to the other craziness.

Lots of fun can be had with Joesph's idea.
