Solar Energy Research
See also: Ben-Gurion National Solar Energy CenterThe Jacob Blaustein Institutes for Desert Research has developed a solar energy research program focusing on how extremes of heat and cold in the desert can be mitigated through efficient storage of heat during the day for release at night.
An adobe house was built with rational fenestration, small windows in the northern side and heat collecting concrete prisms in the windows of the south facing wall. The prisms are situated in the rooms. They absorb heat during the day and can be rotated to allow the heat to discharge into the rooms at night. The "chimney" is part of an evaporative cooling system that maintains the temperature of the house during the day at bearable levels.
A double skin greenhouse uses copper sulfate solution as a heat screen during the day. The liquid is pumped between the two skins, protects the interior from ultraviolet rays and collects heat. At night the liquid is recirculated returning the heat to the greenhouse.
David Faiman of the Solar Center has made advancements in the realm of concentrator photovoltaics CPV. Faiman has produced a CPV unit capable of producing energy at a factor of up to a thousand more than conventional units.

Famous quotes containing the words solar, energy and/or research:
“Lincoln becomes the American solar myth, the chief butt of American credulity and sentimentality.”
—H.L. (Henry Lewis)
“Crime is naught but misdirected energy. So long as every institution of today, economic, political, social, and moral, conspires to misdirect human energy into wrong channels; so long as most people are out of place doing the things they hate to do, living a life they loathe to live, crime will be inevitable.”
—Emma Goldman (1869–1940)
“... research is never completed ... Around the corner lurks another possibility of interview, another book to read, a courthouse to explore, a document to verify.”
—Catherine Drinker Bowen (1897–1973)
