Like many things, it sounds like a great idea but requires some build-out and investment. How long would it take to get that investment back is always the question. But if this innovation in HVAC and building materials -- which can either absorb humidity or release humidity as needed to create the desired temp for much less cost than traditional systems -- can ramp up affordably it could help offset a large expense for every home and building owner.
When water evaporates, it causes a cooling effect. Think about the human body – when we’re hot, we produce sweat which, when it evaporates, keeps us from overheating. When water vapor is absorbed or condenses on a material, the opposite occurs – it generates heat.
