Solar thermal collectors: A solar thermal collector collects heat by absorbing sunlight. The term "solar collector" commonly refers to solar hot water panels, but may refer to installations such as solar parabolic troughs and solar towers; or basic installations such as solar air heaters. Solar power plants usually use the more complex collectors to generate electricity. Simple collectors are typically used in residential and commercial buildings for space heating.
IBM solar collector magnifies sun by 2,000 times (without cooking itself), costs three times less than similar systems. It uses a combination of photovoltaic panels and solar thermal to reach 80% efficiency in conversion of sunlight to energy. Now that's hot!!
This spherical solar collector is able to concentrate sunlight up to 10,000 times. But the really fantastic thing about this system is that it can also create power from moonlight, something that other solar power systems have not been able to promise.
