Space is filled with radiant energy and beyond earth's atmosphere this energy flow more steadily and more intensely from the sun than that which penetrates to the surface of the Earth. So an abundant and essential source of energy that would be used in space for the space colony would be solar radiation by developing satellite solar power stations.
To live in space, humans must be protected from the fierce intensity and penetrating wavelengths of unattenuated sunlight, but this same energy is one of the primary resources of space. The colony will have to have enough energy to maintain a fairly uniform temperature even.
though it is apace. The sun shines twenty-four hours a day and is not dimmed by an atmosphere. Shaded materials not exposed to direct sunlight will almost be at absolute zero. While the temperature in closed bodies exposed to the sun can soar above the boiling point. The colony will need to have both heaters and air conditioners. On the other hand, this sun's energy can be converted into electricity in the colonies. It will be converted with ten percent efficiency to electrical power which is sold at a rate of .012 kw/hr, a square kilometre of space would return more than $14,000,000 each year.
Converting solar power to electricity in space, we would build satellite solar power stations that would intercept the sunlight and convert it into electricity. The satellite solar power stations would intercept enough sunlight to replace five nuclear reactors or coal plants. The stations could be as big as nine miles long and four miles wide and it would only weigh twenty thousand tons. It would be built with hollow triangular girders made of aluminum that is very fast and easy to build . Solar power satellites are a pollution free way to generate electricity and cost no more than coal or nuclear energy. There has been twomajor designed stations made so far. One is designed by Peter Glaser of Author D.
