O'Neill colony オニール型
宇宙活動 / ハイテクノロジー

A cylinder-shaped space colony proposed by Dr. Gerard K. O'Neill. Beyond Coast is the first and last O'Neill colony. Designed by American and European engineers, the shortcomings discovered with the colony, combined with Tokugawa's political influence, have meant that another O'Neill model will not be built. This has led some to argue that the ISPA and Tokugawa are too closely connected. The only designs thus far implemented for mid-sized and above colonies have been the O'Neill model and the torus model, with others, such as the dumbbell and sphere models, yet to be realized.
