Clouds? And some sort of modified Kelvin water dropper to extract the energy from the clouds (without trying to "capture" lightning)??
Water is, in fact, lighter than air. Well, at least in its vapor form. One could, in theory, build a balloon filled with a hot air/water mix. Perhaps paint it black so that it can be heated by the sun, and then cool at night, or cool by turning a silvered side towards the sun.
