Check GOOGLE patents. This concept has been around for a loooonnnng time. It is available on the Maybachs for the roof. The tech is also available for residential/commercial installations, for wall panels/windows. The only down side is the astronomical cost. That's why you don't see it more often - but, as with all tech, the price will come down as production scales up.
@jaquie I think one thing about patents involves materials and application, meaning a patent can't stop you (in theory, assuming I am correct) from making the same tech with better materials. It seems these materials are super cheap, so I don't think existing patents would prevent commercialization (except those damn legal fees should this have a huge market but little financial backing).
Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.
