SunCat Rechargeable Batteries

Designer Knut Karlsen has come up with the innovative idea of integrating flexible solar cells onto rechargeable batteries.

Karlsen’s current battery is just a prototype and isn’t exactly ideal the charging isn’t that efficient and the battery itself has to be smaller to fit all of the extra components but hopefully the design will get significantly better over time.
