Researchers claim to have created a transparent solar collector which is so clear that it could replace conventional glass in windows. Dubbed transparent luminescent solar concentrators, these devices may have the potential to turn any see-through surface into a solar energy collector.
While we've seen transparent speakers before, they've usually consisted of regular opaque woofers and tweeters encased in a see-through body. ClearView Audio's Clio, however, is different. While its base is easy enough to see, the actual sound-emitting part is composed entirely of clear acrylic.
