Buildings represent 30% world energy usage, of which 50% is for heating and cooling. Our technology can reduce these energy needs by up to 50%. This would have a vast impact on CO2 emissions, and wasted energy. Our technology captures a new source of renewable energy – humidity power. When humidity fluctuates, water evaporates and is absorbed, which releases and absorbs large amounts of energy. We use this to power evaporative cooling and absorption heating.
