Heres a different take on the concept of a dyson sphere. For those who dont know, a dyson sphere is an enormous man made environment made of either ring(s) or a sphere with the radius of a planetary orbit. On the inside of this giant structure is a star which gives the environment its energy and warmth and light. See here for more info: [link]
Instead of having one ring, as in ringworld or halo, this sphere has several all locked together at two poles. Night and day are created by the inner rings which are static, with the outer rings rotating around them. Rather than having day and night the same length as in ringworld, a person can choose whether they want longer nights (by living closer to the poles) or longer days (by living closer to the equator). This would allow for massive expanses of ground that is perfect for agriculture where the days are longer, as well as enabling the rings to have some kind of ice caps in order to create an earth like weather system.
Id be interested to know whether anyone has seen a dyson sphere of this design before, because i havent
Modelled and rendered in Cinema4D, tweaked in Photoshop.
