Hey, I have a better idea: why don't we take a sphere, fill it up with mass to create the right gravity. Then we set it at a distance from the sun, so it receives the correct amount of irrdiation, and we spin it to create a day/night cycle. Then we let it orbit the sun at a speed that keeps it exactly in orbit. It is somewhat tougher to map than your ring, but a much more economical use of surface, since you could use all sides of the sphere. Ok, the top and bottom parts will be somewhat less inhabitable, because of the wrong irradiation angle, but we could tilt the revolution axis of this sphere to compensate for that. It sounds like an ideal shape actually. Anyone wish to comment? Maarten
