Scientists develop mega-thin solar cells that could be shockingly easy to produce: ‘As rapid as printing a newspaper’::These cells could be laminated onto various kinds of surfaces, such as the sails of a boat to provide power while at sea.

    Clearly you’ve never owned an air fryer wanted a solar powered car. Or imagine shipping containers covered in these powering the trucks that haul them! Or trains! Even boats. Basically any kind of self powered transit, especially ones with greater surface area.

    Second edit: Another idea! Clingfilm solar panels for windows, or blinds and curtains that can power the lights!

    Or wind turbines skinned in thin, light, flexible solar panels. You’d double dip on energy per square meter. You could have a solar farm on a stick that also makes wind energy.

      If you dream of covering a vehicle with panels and have it driven by that power, I have to burst your bubble. That’s not even nearly enough surface to generate enough power. Perhaps assist in trickle charging battery, sure. But we already have flexible panels, even self-adhesive ones. And again, their biggest downside is not their thickness but efficiency. There will never be a self-propelled vehicle. Just a nature of things.

      As for window blinds, etc. There is already glass that lets enough light through and can generate electricity. Those are even worse when it comes to efficiency due to non-ideal angle, light passing through, etc.

        “We already have technology that doesn’t do those things well enough, so this new technology that won’t see advancement ever has no chance of addressing these issues either.”

        Trickle charge is awesome. Trickle charge the semi during your 8 hour driving shift and then another 8 hours while the trucker is asleep. If that nets half a charge every other day, that’s a charge and a half a week. It’s not self powered like a perpetual motion device, those aren’t real. But regenerative braking is a worthwhile addition to an electric truck. Why wouldn’t solar paper or whatever we want to call it also be part of the solution?

          More like, it would take 8 days of constant sun to have an hour of driving.

              No, there is literally only so much energy radiated by the sun in a certain area. The number of square feet of roof on a car is just too small to propel it, even with magic theoretical 100% efficient panels.

                You do know cars don’t have to move all the time right? If I was on a road trip and got stuck because of no juice for whatever reason, I would be able to camp wherever I am for a couple days and then have enough to move.

                Your thinking is pretty small minded

                  This isn’t some theoretical thing I’m making up. It’s really basic math and physics you should have learned in high school. To do a trip of a few miles you would have to charge for a week. Here is a good explainer with demonstration cars that have been physically built, maybe that will help drive the point home.
