IBM solar collector magnifies sun by 2,000x (without cooking itself), costs 3x less than similar systems

Collaboration aims to harness “the power of 2,000 suns” Scientists at IBM research, Airlight Energy, ETH Zurich and Interstate University of Applied Sciences Buchs NTB attempting to develop a new, economical “High Concentration PhotoVoltaic Thermal (HCPVT) system” using a parabolic disc. Claim the system can “concentrate, on average, the power of 2,000 suns, with an efficiency that collects 80 percent of the incoming radiation and convert it to useful energy.

The 19.9-megawatt Gemasolar CSP power tower plant in Seville, Spain has just set a milestone for solar power plants, it offers 24 hours of uninterrupted operation. This is a first, according to Torresol Energy (a joint venture between Masdar and Sener). The system is capable of 15 hours of electricity production without solar radiation by storing the thermal energy in molten salt.

Heliotrope: The World's First Energy Positive Solar Home

Heliotrope Solar Home in Germany by Architect Ralph Disch. Rotating, it takes full advantage of the sun, allowing daylight to course though its triple-pane windows and energize its large roof-mounted solar array and solar thermal pipes. The result is one of the first zero-energy modern homes in the world — generating five times the energy it uses
