“SPD technology is smart glass that allows you to change the hue of the glass,” Harary explained. “It is this film that we invented, which contains small nanoparticles, which you can control with a small electrical voltage. So basically this movie … that lets you dial in any color step you want. ”
“The crystals are about three to five tenths of a micron in length, and they act as induced dipoles, so when you apply an electric field to the conductive coating in the film,”
As the color partially blocks incoming photons, it also reduces the amount of glare the driver experiences and the heat trapped in the car – over 99.5 percent of the light and 95 percent of the heat, per a press release from the company from January. The claim is that this allows the vehicle’s passengers to stay comfortable longer without having to turn on the air conditioner, as well as keep the interior up to 18 degrees (F) cooler in general, Harary claimed.
“You make the car safer because you lower the center of gravity and reduce the weight of the roof; you use the air conditioner less, said Harary, adding that “Continental Automotive calculated that you can save four grams per kilometer of CO2 emissions,” by using this technology. In places like the EU, where drivers are taxed on the basis of the amount of CO2 their vehicles emit per distance traveled, cutting four grams per kilometer can represent some significant operating costs – around € 380 (~ $ 410) annually on average.
In addition, these weight and energy savings should be translated into longer driving ranges for electric cars, since battery stores are not used to run air conditioning or help haul unnecessary extra weight. Safety and acoustic damping effects also increase – at least compared to a conventional convertible top – since you drive under a sheet of laminated glass instead of an aluminum roof frame and heavy canvas cloth.
We will of course see this technology in Celestiq when it arrives at dealerships in 2023. However, Celestiq – which operates under the auspices of being Caddy’s new flagship EV – is expected to be a handmade monster of a sedan retailing for $ 200,000 and up, not exactly what people Most will consider affordable, especially in this economy. However, Harary remains confident that as technology spreads, consumers will soon begin to see it not only in less expensive car models, but in billboards, advertising campaigns and even modern architecture.
