Coating materials that protect against fire, water or extreme temperatures are nothing new. But an Israeli high-tech paint doesn’t just protect surfaces from the sun. SolCold actually uses the sun’s power to activate a cooling mechanism, effectively providing air conditioning without electricity.

You read that right: This double-layered coating absorbs the hot rays of the sun and re-emits that energy in the form of cold. The hotter the solar radiation the more the coating cools down, making SolCold’s paint a potentially game-changing electricity-free solution for intensely sunny climates such as Africa and Central and South America.

The Herzliya-based startup is raising funds and plans to begin trials within 18 months of closing the Series A round in the first quarter of 2018. Two commercial and one residential building in Israel and Cyprus are waiting to get the trial SolCold treatment.
