The optical duality of tellurium nanoparticles for broadband solar energy harvesting and efficient photothermal conversion | Science Advances
Putting the tellurium nanoparticles directly in the water sounds like a bad plan for an industrial process, but this might lead to a better solid absorber for a thermal receiver?

Potential for natural evaporation as a reliable renewable energy resource | Nature Communications
Using evaporation to generate power, in this case via a piston engine setup. Kinda prefers a dry place though, where water isn't found...

Men's Zero Rules™ Short Sleeve Shirt
Uses Columbia's Omni-Freeze Zero tech, which basically uses water absorbing polymer rings in the fabric to alter the fabric's surface area by tenting to increase evaporative cooling effects. Basically enhanced sweating.

Glass leaf 'sweats' to generate electricity - tech - 30 July 2009 - New Scientist
Oddball energy scavenging system using natural evaporation as a capillary driver. I wonder if this could be built into humidifying systems?

Drinking Water From Air Humidity
Unlike traditional dew collectors, this does not require a thermal gradient or a low side temperature below the dewpoint, so this can be used in really hot places provided you can provide the electricity for the vacuum pump for the evaporator, the brine lift pump, and ancillary equipment
