Did my ability to search for things intelligently on the internet die when Google search did or are there legitimately no personal umbrellas with solar panels and a battery pack? Like I feel like that would be an obvious thing, and there’s a bajillion beach umbrellas and patio umbrellas that have solar panels. How are there no personal versions for wandering around on a sunny day with portable shade that gets you a charged battery pack? Is this a thing and I just can’t find it or does it not exist yet and all of science has failed me in every way possible?
Sorry for the terrible AI picture, I didn’t create it I just found it on the internet and it was the only one I could find because these apparently don’t actually exist.
You’re not gonna be lining a flexible handheld device with the kind of solar panels that can achieve such efficiencies even under ideal conditions. If you want an actual parasol rather than an unwieldy, rigid, parasol shaped bed for a bunch of solar panels, this is a job for the more alternative solar cell types that are cheaper and less efficient, but can be made thinner and lighter, and can be stuck on something like that. Unfortunately those generally have piss poor efficiency and they degrade to near uselessness very quickly.
