This is a solar panel. Really. If you’ve observed that it looks a lot like a piece of live-edge fluorescent acrylic, you’re more than halfway to understanding how it works. Light entering the panel from the sides is absorbed by dyes and converted, by some fancy top-secret nano-metal whatnot ingredients, into a kind of internal re-radiation that is collected by conventional silicon applied only at the edges. Fair warning: Full science-hype disclosure rules apply here. The responsible party is Israel’s GreenSun, and they do not have a product at market yet. But The Economist seems to be buying in, and their ethos is good for a click or two, in my book.
