TOKYO (AP) 鈥� Nissan showed Tuesday what it called a 鈥渃ool paint鈥� to keep people inside vehicles cooler, although the coating is six times thicker, making commercialization still a challenge.
The company's announcement Tuesday was timely, coming as .
Nissan Motor Co. tested the paint on vehicles scuttling around Tokyo鈥檚 Haneda airport, where there are plenty of unshaded areas that make it a good place to assess the technology.
The vehicles with the special paint looked like ordinary cars, but felt much cooler to the touch.
The cool paint lowered the cars鈥� roof-panel temperature by 12 degrees Celsius (22 degrees Fahrenheit) and the interiors by 5 C (9 F), according to Nissan.
Cooling materials already are widely used in buildings and other items. .
has also been experimenting with paint that delivers lower cabin temperatures, mostly focusing on colors that refract the sun's rays.
Nissan鈥檚 cool paint reflects sunlight better and also creates electromagnetic waves that block the rays, redirecting energy away from vehicles.
Nissan鈥檚 paint was developed with Radi-Cool of China, which developed a film, fabric and coating that cut heat. Radi-Cool works with various other Japanese companies, offering cooler-feeling hats and sun parasols. Nissan is the only Japanese automaker partnering with Radi-Cool.
Susumu Miura, a Nissan Research Center manager, said there were no discernable negative effects to people鈥檚 health from the electromagnetic waves emitted by the paint. Such waves are all around us, he said.
鈥淢y dream is to create coolers cars without consuming energy,鈥� he said.
