![]() This can be an issue, since larger windows mean more ions that have to be moved around to block the light. So far, their smart window has only been tested at relatively small sizes of about four square inches, and they hope to scale it up to window sizes to see how fast it will switch back and forth. McGehee and his collaborators have applied for a patent for their invention and are now working to improve it to make it marketable. They've tested this process more than 5,000 times on prototypes, and each time the glass has gone back and forth without a problem. The window glass appears as clear as normal glass in its dormant state, but flip a switch and with 30 seconds it goes dark, blocking up to 95 percent of light. These windows use a mixture of transparent metals within glass that can conduct electricity pumped through it, moving ions around within the metals that can then block light in response to the electricity. In a recent study published in the journal Joule, McGehee describes windows that could make blinds a relic of the past. Inspired by the idea of a graduate from his lab who suggested he take this on, McGehee set off to see if he could improve things without knowing where he would end up. "The products that are available are almost good enough, but just not quite there," McGehee says. The lenses can easily and cheaply change in response to UV light, McGehee says, but they wouldn't make practical smart windows because users would have no control over when they wanted tint and when they didn't. Donald Stookey, the inventor of CorningWare, first patented these glasses in 1950, and they were released commercially starting in 1965. Photochromic lenses, which are often seen in the sunglasses than can "transition" from clear to tinted automatically, have also been around for a long time. But these existing smart windows haven't been perfect, McGehee says, noting that they are expensive, slow (often taking 20 minutes or more to fully tint, depending on their size) and the light passing through them is often tinted blue when they're transparent. Smart or dynamic glass that can go from transparent to tinted and back is not a new innovation- it's existed for decades in various forms, and has even made its way onto airplanes. "So many people have beautiful views out of their offices and their homes and they lose their views" when they have to pull blinds or curtains over a gorgeous sunset or a bright, clear day, McGehee says. In 1841, it was American John Hampson who actually received a patent for a method to keep the slats of a blind in place by turning a rod or pulling a cord, creating blinds as we know them. ![]() Blinds may date back to ancient Persia, but the first models of them were developed in Europe in the 18th century. He compares how humans respond to glare now from windows as akin to being as crude as wearing glasses with small metal slits that can open or close to shield our eyes. "I think it's going to be a game changer," Stanford University engineer Michael McGehee says of his dynamic windows. But what if instead, you could simply press a button and instantly make your window tinted? A new technology promises a future where that could be possible. ![]() We sincerely hope that we can keep good cooporation and joint development with all friends at home and abroad.When the sun is beaming through your window and into your eyes, the solution nowadays is the same as it's long been-blinds.
