Researchers from Purdue University create the whitest paint that can ultimately reduce the need for air conditioning

Scientists from the mechanical engineering department of Purdue University have created the whitest paint in the world. The paint is can reduce or eliminate the need for air conditioning because of its color. The paint has its name in the Guinness Book of World Records for being the whitest paint ever made. The main purpose behind the creation of this paint is to curb the global warming caused by the increased usage of air conditioners and fight climate change.

The primary idea of the scientists was to make a paint that would quickly reflect sunlight away from a building. Keeping this in mind, the researchers from Purdue University made sure that the paint was reflective; also, they made it white. That being said, the paint will reflect 98.1 percent of solar radiation. Also, the paint will emit infrared heat as it absorbs less heat from the sun than it emits.

A high concentration of barium sulfate and different particle sizes of barium sulfate in the paint make the paint whitest. The scientists at Purdue University have stated that if we use this new paint to cover an area of about 1,000 square feet, it will have a cooling power of 10 kilowatts, which is more powerful than the air conditioners currently used.
