Uh, so releasing charged droplets from a wind permiated panel somehow generates large DC voltage differentials that can be harvested for power.

SPRAY TURBINES TO INCREASE RAIN BY ENHANCED EVAPORATION FROM THE SEA
Turns out ocean surface layer humidity made this not work as a rain maker, but the interesting takeaway is the inductively charged electrospray method for generating fine water droplets. "The device consists of an anodized titanium spring half-embedded lengthwise in a rubber block, with the fluid passing through the spring so that the gaps between turns of the spring form spray nozzles. The diameter of these nozzles can be collectively adjusted by stretching the spring and its rubber matrix . Insulated conductors at high voltage run alongside the spring, and the droplets are thus charged by induction as they pass by the wires, resulting in a finer spray and better dispersion as well as making the droplets attract neutrally charged particles such as particulate pollution. The droplet size is also controlled by a ~1MHz ultrasonic input." This can be used for things like trying to capture airborne particulates in smoggy areas. By the "Salter's Duck" wave power generator dude too.
