       this is incredible. Hanging solar panels a few meters above crops of tomatoes and jalapeños multiplied their yield 2-3x, used substantially less water, controlled temperatures, and increased the output of the solar panels https://www.pnas.org/doi/10.1073/pnas.2301355120 #science #solar #environment #agriculture

       they mention reducing evaporation off lakes and ponds in hot arid climates by covering them partially with solar panels. seems like cities could also use solar panels to reduce heat diffusion, maybe even make it cheaper to cool

       @KLB @HistoPol @kellogh We are woefully behind in all areas of solar. What sell here? House panels that are marked up substantially. Just make money, and while they help, they aren't solving the bigger issue.

       @Sfwmson @HistoPol @kellogh we still expect individuals to do the heavy lifting (like with recycling), when the problem area is farther upstream.

       (3/8)...without rainfall for some time.I am not an engineer, but it seems quite logic that the reflective capabilities of the #SolarPanels will also protect the organic #soil from #erosión by rain, sun, and to some degree, wind.After some interest in the 1960’s through 1980s and early 2000’s, a 2019 Master thesis from #Italy with the chief aim of #WaterConservation and management takes aim to solve South American cities’ recurring #flood problems using #WaruWaru: https://www.politesi.polimi.it/handle/10589/148696.
