BUILDER/COMMENTS:



A. Twu: "Island Two is a space colony proposed by Gerard K O'Neill in his 1977 book 'High Frontier'. This was the second stage in a series of proposed NASA projects. This space station contains a main cylinder that is 1.8 km in diameter and five times as long. Mirrors reflect light into the living area in the center. At one end of the space station is a ring of farms. About 800,000 people were to live in it."
