Island One
In a series of studies held at Stanford University in 1975 and 1976 with the purpose of speculating on designs for future space colonies, Gerard Kitchen O'Neill proposed Island One, a modified Bernal sphere with a diameter of only 500m rotating at 1.9 RPM to produce a full Earth artificial gravity at the sphere's equator. The result would be an interior landscape that would resemble a large valley running all the way around the equator of the sphere. Island One would be capable of providing living and recreation space for a population of approximately ten thousand people, with a "Crystal Palace" habitat used for agriculture. Sunlight was to be provided to the interior of the sphere using external mirrors to direct it in through large windows near the poles. The form of a sphere was chosen for its optimum ability to contain air pressure and its optimum mass-efficiency at providing radiation shielding.

Famous quotes containing the word island:
“We crossed a deep and wide bay which makes eastward north of Kineo, leaving an island on our left, and keeping to the eastern side of the lake. This way or that led to some Tomhegan or Socatarian stream, up which the Indian had hunted, and whither I longed to go. The last name, however, had a bogus sound, too much like sectarian for me, as if a missionary had tampered with it; but I knew that the Indians were very liberal. I think I should have inclined to the Tomhegan first.”
—Henry David Thoreau (1817–1862)
