# Temperature-Reducing Paints This White Paint is Engineered to Cool Surfaces Down By Elena Rahman | Published 2021-04-29 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/white-paint References: [ecowatch](https://www.ecowatch.com/white-paint-air-conditioning-2648498534.html) & [purdue.edu](https://www.purdue.edu/newsroom/releases/2021/Q2/the-whitest-paint-is-here-and-its-the-coolest.-literally..html) Engineers from Purdue University have created white paint that could revolutionize the way we use air conditioning systems. The cutting-edge paint reduces surface temperature by 18 degrees Fahrenheit without consuming any energy at all. According to the engineers on the project, the paint works by repelling heat away from the surface it's painted on and absorbs a minimal amount of solar energy. The white paint can be used on the tops of buildings to cool the entire structure down and repel heat towards the atmosphere. It is important to note that not only does the paint works by pushing heat waves away from its surface, it actually pushes the heat beyond the Earth's atmosphere and into deep space, where heat travels indefinitely at the speed of light. Thus, this technology could be a pivotal tool in the fight against climate change by cooling down the Earth's surface.
