Bernal Sphere - Island One

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:

    They all came, some wore sentiments
    Emblazoned on T-shirts, proclaiming the lateness
    Of the hour, and indeed the sun slanted its rays
    Through branches of Norfolk Island pine as though
    Politely clearing its throat....
    John Ashbery (b. 1927)

    Know that, on the right hand of the Indies, there is an island called California, very near to the Terrestrial Paradise, which was peopled with black women.... Their arms were all of gold.
    —For the State of California, U.S. public relief program (1935-1943)
