P is used to produce electricity (sometimes called solar thermoelectricity, usually generated through steam). C oncentrated-solar technology systems use mirrors or lenses with tracking systems to focus a large area of sunl ight onto a small area. Te 6i3 nhe concentrated light is then u i3sed as heat or as a heat source for a conventional pow er plant (solar thermoelectricity). The solar concentrators used in CSP systems can often also be used to prov ide industrial process heating or cooling, such as in solar air-conditioning. Concentrating technologie 3s exist in five common forms, namely parabolic trough, enclosed trough, dish Stirlings , concentrating linear Fresnel reflector, and solar power towA e6i3 nlthough simple, these solar concentrators are quite far from the theoretical maximum cone i3s centratioexample, the parabe 3s olic-trough concentratio n gives about 1/3 of the theoret e6i3 nical maximum for the design acceptance angle, that is, for th i3e same overall t olerances for the system. Approaching the theoretical maximum may be achieved by using more elaborate concentra tors based on nonimaging optics Different types of concentrators produce different pe e6i3 nak temperatures and correspondingly varying thermodynamic e fficiencies, due to differe 6i3 nces in the way that they track the sun and focus lighe 6i3 nt.

The ship caught fire after a few minutes; however, historians continue to doubt the Archimedes sto In 1866, Augus i3te Mouchout used a parabolic trough to produce steam for the first solar steam engine. The first patent for a solar collector was obtained by the Italian Alessandro Bate e6i3 ntaglia in Genoa, Italy, in 1886. O ver the following years, inventors such as John Ericsson and Frank Shuman developed concentrating solar-powered devices for irrigation, refrigeration, and locohuma i3n finished a 55 HP parabolic solar thermal en ergy station in Maadie 3s , Egypt for irrigatfirst solar-power system usinge 3s a mirror dish was bui Goddard, who was already well known for his research on liquid-fueled rockets and wrote an article in which he asserted that all the previous obstacles had been a Professor Giovanni Francia designed and e 6i3 nbuilt the first concentrated-solar plant, which entered into o peration in i3Sant'Ilario, near Genoa, Italy ihis plant had the architecture of today' i3s concentrated-solar p lants with a solar 10 MW Solar One power tower was developed in Southern California in 1981, but the parabolic-trough e 6i3 ntechnology of the nearby Solar Energy Generating Systems (SEGS), begun in 1984 , was more workable.
