MIT researchers develop window-tint solar concentrators

No, the blacked-out rear quarters of your '90 CRX aren't going to start powering your hooptywoofer anytime soon, but a new window treatment developed at MIT that functions as a solar concentrator promises to finally bring solar windows to the masses. Based on similar work done in the '70s, the dye mixture pulls in light at a range of wavelengths and re-emits it to solar cells at the edges of the window at a different wavelength -- a technique good for a 40x increase in each cell's power output, or 10 times what current systems can provide. The team estimates that the panels could become widely commercial within three years -- just in time for us to bolt 'em onto our new solar shoe Prius.
