The Bernal Sphere

The Bernal Sphere was first proposed by John Desmond Bernal in 1929. The original description of the design was a hollow, spherical shell filled with air. In 1976 Dr. Gerard K. O'Neill proposed a new and improved version of the colony. He called it Island One. The entire thing is spinning really fast to make a force equivalent to one G, or one Earth gravity. The closer to the center that you get, however, the less gravity there is. There is a window going around the equatorial zone that is right next to a mirror. This mirror reflects sunlight in to produce a false sense of daylight. There are small Stanford Taurus' rotating around the tips of the Colony that are used for agricultural purposes; supplying food for the colony. Massive superconducting solar panels produce all of the energy for the colony. A later version of the colony can support a lot more people. All in all, the colony could be a great alternative to our current situation. All of the colonies could. Thanks, Aidan.
