With energy prices rising rapidly, a new startup could have the answer - technology that harnesses energy from fluctuations in humidity to cool and heat buildings at half the current price.

Israeli startup ThermoTerra is turning that vision into a novel renewable energy system that harvests energy from fluctuations in humidity. “Water vapor in the air that’s absorbed onto or into an absorptive material transfers a significant amount of energy,” explains ThermoTerra founder and CEO Dror Zchori.
