Solar power is everywhere at the mo, maybe because it sounds more sci-fi than wind: which is the case with this new technology that turns windows into power sources. Clever bods at MIT have worked out how to use organic dye solar-concentrator coatings to collect light over a whole sheet of glass and “concentrate” it at the edges. This lets you have a much smaller (and hence cheaper) solar-electric cell mounted in the side of a window, more easily achieved than typical mirror-based concentrators. And by tuning the dyes (originally designed for lasers and OLEDs) to different wavelengths, and stacking them up, you get an even bigger power output. Clever stuff. [Physorg]
