I think this is fascinating! Engine type 1 can produce energy while retarding the evaporative water loss from surface waters (presumption of still waters, I think).
Engine type 2 produces circular motion, could turn small generator, then the sky is the limit (water purification schemes come to mind, where some of the evaporated water is collected by sub-cooling. Battery charging, powering communications, etc.
They even have a gerbil car (not big enough for humans, yet).

The head is cooler than the base due to evaporation. Methylene Chloride condenses in the head and evaporates in the base, moving the liquid higher in the neck. When the center of gravity gets high enough, the bird dips down, dumping the liquid back in the base, and the process starts over.
It's a heat engine driven by the temperature difference due to evaporation.
