space colonization ship

This is a concept of a newly designed space colonization ship (This model can be 3D printed separately). Eight large cabins are connected to the central cabin by 16 tubes which have elevators inside. Passengers' living area is in these cabins surrounded the central cabin. The elevators execute the task to transport people and goods from the living cabins to the central cabin. The living cabin has the ability to rotate around the central cabin as 8 sets of two-side engines are installed on the living cabins. this can provide centrifugal force, so gravity is generated.There are 40 ports near the central cabin, which provides connection to the transporting ships. The operation cabin is at the very front and has its only electricity supply. the laboratory array is behind the central cabin, which provides scientist with a chance to study the alien things. The laboratory is followed by oxygen generating cabin array which ensures the oxygen supply of the whole ship. At the very end of the ship, there are the nuclear fuel cabin array and the main engine. They are the power sources of the whole ship. heating panels are installed next to the oxygen generation cabin, fuel cabin and the lab cabin to emit the extra heat generated during the reactions in these cabins into the space and avoid damaging the ship. There are also a number of sub-engine arrays which are used to control the direction of the ship.
