Sopogy Shrinks CSP For Efficient, On-site Use

Soponova

It seems like there’s a new, cutting-edge technology in the limelight everyday and today is no exception.  You’ve heard of CSP — concentrated solar power, right?  Well Sopogy has been in R&D for several years perfecting their MicroCSP technology.  They developed the above pictured application for commercial, industrial, and small utility uses.  MicroCSP takes traditional, large scale, open faced, desert, parabolic trough CSP panels and shrinks them down to 25% of the size.  The trough is between 12 and 18 feet long and is meant for distributed energy solutions from 200 kW to 20 MW.  It can be used on-site, too, whether on a roof or adjacent to a building.

Covalent Solar to Commercialize Low-Cost Organic Solar Concentrators

Covalent Solar rendering

The innovators of this new technology, if they get it into production, may just be the green building revolutionaries of tomorrow.  At the end of the week, MIT engineers published research of new technology showing that the sun’s energy could be harvested from a large area, such as a window, and concentrated at the edges by solar cells.  With this so-called luminescent solar concentrator, the potential for low-cost electricity seems almost within reach.  Technically, here’s how it works:
