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

    if you find this interesting, you may enjoy reading Into the Cool, a book all about non-equilibrium thermodynamics and it’s relation to climate change (and what to do about it) https://www.goodreads.com/en/book/show/52737

    @kellogh@hachyderm.io my favorite part of that is the name: floatovoltaics

    @kellogh@hachyderm.io The tax rate on a parking lot that hasn't got solar panels over it should be thereabouts of a thousand dollars per square meter per month.

    @kellogh@hachyderm.io Solar panels will passively cool your home as they do take energy that would have been heat and turn it into electricity. If I ruled the world I would mandate all supermarket car parks to be covered with solar panels.

    @kellogh@hachyderm.io Sort of. In the case of sealed surfaces and concrete features, definitely yes. If the choice is between planting a tree and putting up an equal area of solar panels, plant the tree.

    @kellogh@hachyderm.io I saw a reservoir with a gazillion floating, plastic balls on the surface. It was to reduce evaporation, but also cut down on algae growth in the water basin.

    @kellogh@hachyderm.io I remember the water crisis of capetown where they tried to reduce evaporation by covering their water reservoirs with black rubber balls. Using solar panels instead is a win-win in that case. I mean let's be honest, climate change will escalate this in the next years and not only in africa.

  • @kellogh@hachyderm.io I honestly think everyone would benifit if we just covered all the massive parking lots this way. The business gets power and maybe excess it can work with, and customers get covered parking for protection from weather.

  • @kellogh@hachyderm.io interesting. l assume they have taken in account that life in the water need sun and oxygen from the air to survive? Not to mention high evaporation in dry climates actually is normal and stopping it might harm local wildlife and flora on a larger scale?
