Camels live in the driest climates on earth, and yet they’re somehow able to function with limited water resources. So scientists have taken a hint. Camels conserve water by cooling exhaled air during the night, extracting water vapor from the exhaled air, and absorbing and holding onto water molecules from the surrounding air.
Researchers in the Sahara Desert are using the same technique to remove salt from saltwater to irrigate plants by using cool ground water to evaporate warm sea water, which is then condensed in a salt-free form.
