So an umbrella?

• PaulHoule 1y ago
  Yeah, but like an umbrella made by something like Drexler's nanotechology.

    How about something more ... Realistic https://www.thebrighterside.news/post/mits-high-tech-hydrogel-window-pulls-clean-drinking-water-from-dry-desert-air/ https://www.thebrighterside.news/post/mits-high-tech-hydroge...

      That's the opposite of a tree, which turns drinking water into nothing

        "Water harvesting" has been around for a long time. I think I first saw a water harvesting device in the U.S. Army Survival manual in the 1980s. It's an active research area and devices continue to improve.

          Passive? Hydrophobic+Dessicant? dew collector? In the desert? Dew collector seems to make the most sense for 1980

  If we're being condescending: 'So, a parasol?'.

    I wasn't trying to be condescending, just trying to point out that trees might not be the most viable structure. Last time I was in southern Arizona when I wanted some relief I'd just find a solar panel installation in a parking lot and hang out under that.
