Virtually any source of heat can be used to generate electricity. Recently,power plants have been built that use sunlight to produce steam.
Generation From Solar Light System
The sun’s thermal radiation delivers about 1,000 Watt of heat to each m2 of the earth’s surface. While that isn’t enough heating for a normal boiler, concentrated sunlight can boil water fast enough to produce high-pressure steam. Most thermal solar power plants use mirrors to concentrate sunlight onto their boilers.What is important here is that mirrors redirect the path of light and can be used to concentrate sunlight onto a boiler.One possible arrangement of mirrors is the parabolic reflector. A parabolic mirror can take all of the light from one distant source (e.g. the sun) and focus that light together. If the mirror is parabolic all the away around, like a bowl, then it focuses light to a single spot. If it’s parabolic only in one direction and extends as a trough in the other direction,then it focuses light to a line. In either case, it can concentrate sunlight tightly enough to boil water, produce steam, and operate a turbine.
