  Never used an umbrella to shield yourself from the sun?

    I actually did not, and here around, I don’t see anyone do that. I believe climate and culture are the factors influencing the popularity of using an umbrella as mobile shade.

  Im beginning to see more people actually parasoling in the southern US and if im being honest… I’ve been tempted given how our heat and UV measurements are going.

    Interesting. It appears that it is one side effect of climate change.

    Side note: PV panels try to absorb a lot of light. Parasols try to reflect it, which is why they usually have a bright color. Imagine now holding an umbrella, absorbing more energy than your skin/hair would, causing you to sweat even more?

  Have you heard about solar roadways?

  :-)

    I think there are some test roads in the Netherlands on the bike lane. Roads are used in all weather conditions, 24/7. Umbrellas not. Roads have approximately the same energy yield as any solar panel on the roof, minus the suboptimal angle and minus the road users causing shadows.

      If you don’t see the absurd part in trying to put solar panels as a road then I’m sorry I can’t do anything for you 😁. There are exactly 0 practical reasons to do so.

        There is nothing absurd about it. Every surface, which is constantly exposed to the sun, should be covered in PV panels.

  Umbrellas are used in sunshine and are often called parasols. It’s not a bad form factor, it just seems to have practical limitations, like being foldable and still useful. Love the idea, though.

  Japan is ready. Other places can be made ready. It isn’t hard to prepare people for bikes or whatever. Solar panels on everything are potentially a good idea. I only worry that my umbrellas do not last.

    Wait til a big gust of wind comes through and shatters your solar panels by inverting the umbrella/parasol.

  Beach umbrellas are mostly used on sunny days so I can see that.

  What about parasols

  • zr0@lemmy.dbzer0.com ⁨10⁩ ⁨months⁩ ago

    Different device, similar features. They tend to be much larger, making the weight an even bigger issue.

  Some areas still use the for just sun protection. Agree that it would not be a global product for now.
