The principle known as Landauer's Limit says that the maximum theoretical efficiency of a computer is directly related to its temperature. A computer operating at seven degrees Kelvin is about 100 times as efficient as one operating at room temperature on Earth. This makes it easier to build computers that are far smaller and are less limited by the speed of light, further increasing their efficiency. Hermite Crater on the north pole of the Moon is naturally about 26 Kelvin. Solar power is very easy to generate on the Moon. Institutions on Earth will transmit the programs over a radio link just as easily as if the computers were on Earth and with little more delay. Massive frozen computing systems will return the answers. Both Shackleton Crater on the south pole of the Moon and Hermite Crater will be used for the ultimate remote network backup facilities as well.
