New tweak on seawater uranium extraction, by charging the capture medium to collect more ions. Not totally passive compared to previous methods though as a result.

Save 50 dollars on Mistbox with this code:
Basically this sprays the coil unit with water, making this a poor man's version of a deluge evaporation cooler. Naturally, if the humidity is high this becomes less worthwhile. You probably would get better results pressure washing the fins/coil assembly monthly to keep it clean.

Magnetic quantum ratchet effect in graphene : Nature Nanotechnology : Nature Publishing Group
Interesting research, basically making a magnetic quantum ratchet out of graphene, effectively making an AC/DC rectifier. But, they used a 7 tesla mag field and a 3.34THz AC input (between IR and microwave), so not entirely practical. But, infrared nanoantennas have a need for rectifying their AC output and they are currently manufactured in the IR range, so if you can somehow provide the necessary mag field, that might be the trick to make it work...

CoolWare Personal Cooling System: The Air Conditioner You Can Wear Around Your Neck
Hitting the neck and the exposed veins is a good path for cooling, but the water requirement means it's probably doing evaporative cooling, so high humidity will hurt performance.

Solar Cogeneration, Cogen, Power, Hot Water | Cogenra Solar
Basically this is a water cooled combined heat and power CHP concentrating solar PV trough design that recovers PV coolant heat for domestic hot water use. The low cost innovation seems to be the fresnel lens style segmented flat panel parabolic glass mirror array that makes up the trough, since flat mirrors in long planar sheets are cheap. New version also does AC via an adsorption chiller
