bjbj take the natural heat from the sun, reflectit against a mirror, focus all of that heat on one area, send it through a power system,and you've got a renewable way of making electricity. it's called concentrating solar power, orcsp. now, there are many types of csp technologies. towers, dishes, linear mirrors, and troughs.have a look at this parabolic trough system. parabolic troughs are large mirrors shapedlike a giant "u." these troughs are connected
Types Of Solar Panels, together in long lines and will track thesun throughout the day. when the sun's heat is reflected off the mirror, the curved shapesends most of that reflected heat onto a receiver. the receiver tube is filled a fluid. it couldbe oil, molten salt something that holds the heat well. basically, this super hot liquidheats water in this thing called a heat exchanger
and the water turns to steam. the steam issent off to a turbine, and from there, it's business as usual inside a power plant. asteam turbine spins a generator and the generator makes electricity. once the fluid transfersit heat, it's recycled and used over and over. and the steam is also cooled, condensed andrecycled again and again. one big advantage of these trough systems is that the heatedfluid can be stored and used later to keep making electricity when the sun isn't shining.sunny skies and hot temperatures make the southwest u.s. an ideal place for these kindsof power plants. many concentrated solar power plants could be built within the next severalyears. and a single plant can generate 250 megawatts or more, which is enough to powerabout 90,000 homes. that's a lot of electricity
to meet america's power needs.
