Peak Energy relays word that a Californian developer has signed with South African firm to sell licenses to build modular 46-MW power plants. Sizzling Kangaroo Bangers, BG, more solar thermoelectric.
AG readers may recognize the California firm as one of the first companies to have received support from Google.org. eSolar plans to take their solar thermal technology to Sub-Saharan Africa.
eSolar developed a modular, scalable solar thermal power technology that focuses thousands of mirrors on a single point to efficiently harvest the sun’s energy and reduce costs.
The key element of eSolar’s technology lies in software that operates the solar field with the necessary degree of precision and reliability.
The type of concentrated solar thermal design is known as a power tower. BG quotes Brian Fan, senior director of research for the Cleantech Group, who acknowledges that troughs are dominant design at present. On the other hand, the power-tower concept is now being tested in the field. “Because of higher thermodynamic efficiency and higher scalability, I believe [the] power tower will be the next generation of CST plants past 2012,” he said.
