Pour of molten alumimum melted with Annular Fresnel solar collectors Solar researchers at Fraunhofer Chile have designed, built, and tested a complete solar collector and crucible system for melting and recycling aluminum, heated by Annular Fresnel solar collectors. In Annular Fresnel, each mirror is flat, like a Fresnel mirror, but arranged in a circle, enabling …

solar tower sCO2 cycle calcination Solar calcination + sCO2 cycle In a year-round California-based study, a Chilean research team has continued to advance a potentially more cost-effective and efficient form of Concentrated Solar Power (CSP) that leverages limestone’s heat generation during calcination. In this new solar tower form of CSP, the solar receiver in the …

IMAGE ©NASA Daedalus crater shows the problem the indirect solar receiver solves. Orlando’s team proposes positioning solar concentrating mirrors – heliostats – atop the crater rims, aiming concentrated solar irradiation down into the darkness of the crater, with the light focused onto a solar receiver partly embedded in the icy surface to heat it to …

A small pipe extending along the central focal point of the parabolic trough is the solar reciever in Trough CSP Researchers have developed a completely different way for Trough CSP to collect solar energy. Normally, in this form of Concentrated Solar Power (CSP), long lines of huge ‘trough’-shaped parabolic mirrors move slowly all day as …
