Mrigakshi Dixit of Interesting Engineering reports on a new development from Nissan.
- Nissan has developed an innovative “cool car paint” in collaboration with Radi-Cool that can significantly reduce both exterior and interior temperatures of vehicles, potentially by up to 22°F (12°C) outside and 9°F (5°C) inside.
- The paint uses advanced metamaterials with unique light-reactive particles that deflect heat-generating sunlight and create opposing electromagnetic waves to disperse energy away from the vehicle.
- The paint has shown promising results in real-world testing at Tokyo’s Haneda Airport, demonstrating resistance to various environmental factors while maintaining its cooling properties, with potential applications extending to a range of commercial vehicles.
“While radiant cooling paint is commonly used in buildings, its thick texture and chalky finish make it unsuitable for vehicles. Nissan set out to overcome these constraints to develop a car-friendly version with a clear finish and sprayable application.”
