Moist air may friz your hair, but science can now use it for green energy, as well.

As we prepare to enter the dog days of summer, it’s probably best to remind ourselves that when it comes to excessively uncomfortable seasonal climates, “it’s not,” as the cliché goes, “the heat. It’s the humidity.” As it happens, that same turn of phrase is also the key to an exciting development in green energy that might one day help power some of our smaller gadgets and gizmos, using nothing but airborne moisture. Yes, the same abundant, and entirely free, humidity that makes the summer so unbearable may someday help power the very air conditioning that saves us from the heat.
