The energy from the sun incident on the surface of the earth averages 32.0 cal/(min-cm2). It has been proposed to use space stations in synchronous orbits 36,000 km from the earth to collect solar energy. How large a collection surface is needed (in m2) to obtain 108 watts of electricity (equivalent to a typical 100 MW power plant)? Assume that 10% of the collected energy is converted to electricity.
The question belongs to Chemical Engineering and the question is about converting sun’s radiation into energy by using photovoltaic cells in space stations. The solution discusses whether or not it is economically or ergonomically viable.
