I would not have thought the super-powers of evaporation would save us from ourselves, but here we are. From Nature Communications and Ahmet-Hamdi Cavusoglu, Xi Chen, Pierre Gentine & Ozgur Sahin:
Abstract
About 50% of the solar energy absorbed at the Earth’s surface drives evaporation, fueling the water cycle that affects various renewable energy resources, such as wind and hydropower. Recent advances demonstrate our nascent ability to convert evaporation energy into work, yet there is little understanding about the potential of this resource. Here we study the energy available from natural evaporation to predict the potential of this ubiquitous resource. We find that natural evaporation from open water surfaces could provide power densities comparable to current wind and solar technologies while cutting evaporative water losses by nearly half. We estimate up to 325 GW of power is potentially available in the United States. Strikingly, water’s large heat capacity is sufficient to control power output by storing excess energy when demand is low, thus reducing intermittency and improving reliability. Our findings motivate the improvement of materials and devices that convert energy from evaporation.
I think this is a calculation of potential. Consider this:
Recent advances in water responsive materials8,9,10,11 and devices12,13,14,15 demonstrate the ability to convert energy from evaporation into work. These materials perform work through a cycle of absorbing and rejecting water via evaporation. These water-responsive materials can be incorporated into evaporation-driven engines that harness energy when placed above a body of evaporating water (Fig. 1a–c). With improvements in energy conversion efficiency, such devices could become an avenue to harvest energy via natural evaporation from water reservoirs.
A quick glance through the paper did not reveal any consideration of negative consequences of actually harvesting this energy.

The peer-reviewed study, led by scientists from The Nature Conservancy and 15 other institutions, and published today in the journal Proceedings of the National Academy of Sciences, expanded and refined the scope of land-based climate solutions previously assessed by the United Nations’ Intergovernmental Panel for Climate Change (IPCC). The findings are expected to bolster efforts to ensure that large-scale protection, restoration, and improved land management practices needed to stabilize climate change are achieved while meeting the demand for food and fiber from global lands.





Now that gravitational-wave detection is likely becoming a regular occurrence—we’ll probably find evidence of many more in the next few years—physicists are again pondering an obscure detail about gravitational waves that was once also thought virtually impossible to observe—gravitational-wave memory, which involves permanent changes in the distance between two objects.
Ever have a hankering to know just what the legendary
