Fabrication of polymeric lenses using magnetic liquid molds: Applied Physics Letters: Vol 114, No 20
Effectively using a ferromagnetic-style formable liquid to make a custom mold for lens, rather than paying a bundle for a custom lens mold from tool steel.

This is borderline cooling version of a perpetual energy generator, but this is an interesting take on fog net concepts. By lightly ionizing the fog and the capture mesh/net, you can get fog droplets to condense better on the net and exceed normal fog nets (which capture 1-3% of passing droplets).

Appears to use metal nanoparticles in a liquid droplet inkjet process. Metal nanoparticles can apparently melt at room temperature, so this printer operates in ambient atmosphere/temperature

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.
