Cooling Polymer Coating

Cooling Polymer Coating
DESCRIPTION
PROBLEM
With temperatures rising and heat-waves disrupting lives around the world, cooling solutions are becoming ever more essential. This is a critical issue especially in developing countries, where summer heat can be extreme and is projected to intensify.
SOLUTION
A paint-like material that facilitates passive daytime radiative cooling (PDRC), a phenomenon where a surface spontaneously cools by reflecting sunlight and radiating heat to the colder atmosphere. No electricity is needed to realize such cooling, making it especially suitable for developing countries and remote areas.
Previously, PDRC materials were complex and costly and could not be implemented or applied to rooftops and buildings with different shapes and textures. My solution is as simple as a paint for arbitrary surface.
CHALLENGES
Production at scale and commercial viability have yet to be determined.
IMPACT
The paint will save considerable electricity for cooling in warm and hot areas (e.g. India, Africa, and Latin America). The climate change has resulted in extreme heat wave in various countries, especially those underdeveloped. However, these countries do not have enough electricity to provide cooling for the community. This paint will effectively reflect sunlight, reduce building temperature and electricity consumption, enhance comfortability of people, and reduce heat stroke and death induced by high temperature.
