Despite the paint being six times thicker, its commercial viability remains a challenge.

The timing of Nissan's announcement couldn't be more fitting, coinciding with Japan's struggle against unprecedented heatwaves. Conducting tests at Tokyo's Haneda airport, where unshaded areas abound, allowed Nissan to evaluate the effectiveness of this innovative solution.

Vehicles coated with this special paint appeared ordinary but felt remarkably cooler to the touch. Nissan reported a significant temperature reduction of 12 degrees Celsius (22 degrees Fahrenheit) on the roof panels and 5 degrees Celsius (9 degrees Fahrenheit) inside the cars.

Efforts to incorporate cooling materials in various products, including buildings, have been ongoing. Cooler cars not only lessen the reliance on air conditioning but also alleviate heat-related strain on engines and electric vehicle batteries.

Toyota Motor Corp. has also been exploring similar paint technologies to lower cabin temperatures, primarily focusing on hues that reflect sunlight. In contrast, Nissan's cool paint not only enhances sunlight reflection but also generates electromagnetic waves that deflect rays, diverting heat away from vehicles.

Collaborating with China's Radi-Cool, known for developing heat-reducing films, fabrics, and coatings, Nissan has taken a significant step towards creating a more comfortable driving environment. Radi-Cool, in partnership with several Japanese companies, offers products like cooling hats and sun parasols, with Nissan being the sole Japanese automaker to join forces with them.

Susumu Miura, a manager at Nissan Research Center, reassured that the electromagnetic waves emitted by the paint pose no discernible health risks, emphasising their omnipresence in our surroundings. Miura expressed his aspiration to craft cars that are cooler without increasing energy consumption, underlining Nissan's commitment to innovation and sustainability.
