Survivors of a far flung Earth
+0

When the earth is flung out of the solar system as per Josh Pirhi's question, not everyone embarks on a spaceship. Instead, as earth becomes a rogue planet, a group of survivors created a self sustaining colony around a cluster of geothermal vents.
My question is simple. Is it possible, with technology from modern day to thirty years from now, to create a self sustaining colony that uses geothermal vents for energy?
Note - I would like the colony to be able to support half a million people at most, and 10,000 at least.
