This short animation shows my model of the Bernal Sphere Space Habitat. (No sound this time). Full HD.

The idea is that people live on the inside of a rotating sphere – the hoops on either side of the sphere contain agricultural areas, and there are rings of mirrors to direct light  in the right places. The big vanes are to dump excess heat in order to control cooling.

For this animation I used light from the side, as it shows the shapes better. To be accurate it should shine along the main axis instead.

The resemblance to Babylon 5 is not a coincidence, the design for that series was loosely based on the Bernal Sphere too.
