Generation ship design project

[stevebowers]

Here are the results of the Hyperion design competition, and they are very good. First place is the Chrysalis design, a 36 mile-long ship that loses several stages en route, and eventually delivers a much smaller (but still impressively large) rotating space habitat to the system.
Can't see any radiators, though.

Some of the other entries are good too; the Endless Beyond the Stars entry looks like it might work; but the retrorockets look dangerously close to the habitable space.
