Generation ship design project

[Rynn]

The design of the habitat and buildings is much less important than the 'technical systems', especially the ecological life support systems and the acceleration and deceleration systems. If you can't accelerate the payload or maintain the ecology you'll never get there, no matter how well your environment is designed.

Not to mention the needed design of the economy to ensure there are sufficient workers and industrial complexity/capacity for a closed system. Plus the social institutions that would be needed to ensure the delicate ecosystem/economy in a bubble survives without some conflict causing it all to crash down.
