Sometimes you see an invention and it’s abundantly clear that you are looking at the future, today. That’s the case with these solar powered rechargeable batteries. It’s a solution that’s elegant yet simple- attach a solar cell to the outside of batteries. When your batteries run out of charge, just leave them by a window or a light fixture to charge up. Great for travel.
These are a homemade prototype called SunCat batteries, created by wrapping a flexible photovoltaic cell around a standard battery. Right now it’s simply attached with a flat wire which trickles the energy, so it barely provides enough juice to power the battery in any sort of timely manner. However, this is just a prototype proof of concept type product, so we should expect further innovations and advancements to it soon. I can totally see this being produced in the future.
