So there are already rechargeable batteries, and there are already solar-powered devices to charge batteries, but what if you could make a rechargeable battery that was completely self-contained, that all you had to do was put it in the window and let it charge?
Knut Karlsen asked this very question, and actually did something about it. Currently just a proof of concept, Knut was able to wrap a flexible solar cell around a battery, and wire it in such a way that it would charge itself. Right now, all it gets is a trickle, but with the proper redesign (incorporating circuitry and the like) it could be incredibly useful. I know for a fact that would be a product that I would want to buy.

if he were to get this right i’d imagine it could make him a fortune. I think everyone would want them
Wait wait wait… So you are telling me that the “Do not expose directly to the sun, keep it away from heat sources” stuff is not real?
Seems like trouble if you ask me. Now, develop a solar panel i can put by the window and safely connect my rechargeable batteries and I’m in (put a suction cup and a velcro thingy so I can easily put it on any window or carry it outside my backpack!).

Sorry if I double posted

Hey, thanks for the post, I’m looking for more of a step by step guide that I can download and print. Know of anything?
