She covers history, science, travel, food and beverage, sustainability, economics and other topics. These existing paints are better than nothing, but the researchers wanted to experiment with materials that could reflect, rather than absorb, the suns UV rays. It's common sense: When it's hot outside, don't put on a dark shirtwear white instead. (Along the way, they also developed an earlier ultra-white paint made from calcium carbonate that reflected 95.5 percent of sunlight.). There is a little bit of room to make the paint whiter, but not much without compromising the paint. We use a lot of white in our design, both for interior and exterior, and can see multiple uses for this paint. Our paint does not use any power but, more importantly, it sends the heat to space. The paint became. Typical commercial white paint gets warmer rather than cooler when subjected to sunlight or other light sources. Paints on the market that are designed to reject heat reflect only 80%-90% of sunlight and cant make surfaces cooler than their surroundings. Its pretty amazing that a paint can do all that.. The heat doesnt stay on the Earth, so that really helps the Earth to cool down and can stop the warming trend.. Patent applications have been filed for the paint formulation.
