HISTORY OF CSP


  Click the image to enlarge it

The idea of using mirrors to concentrate sunlight is not a new idea. It is said that, in 212 BC, Archimedes used polished bronze shields to focus sunlight, trying to set fire to wooden ships from the Roman Empire which were besieging Syracuse. Although we don't know whether this worked, the Greek navy recreated the experiment in 1973 and successfully set fire to a wooden boat at a distance of 50 metres. Leonardo da Vinci proposed the use of concave mirrors to heat water on an industrial scale.

Early CSP

Ashley Seager, author of the Guardian article about CSP, kindly sent us some descriptions of CSP in the 19th century and early 20th century that he had been sent by a reader. Relevant pages from the two source books are reproduced below. Interestingly, the chapter Can Sun-Power be Used? which is shown here (from TheWonder Book of Engineering Wonders) has the prescient subtitle: An engineering problem that will one day be of vital importance.

Two of the pictures from these books are reproduced on the page of pictures of CSP plants.
