Via Inhabitat:Inventor Knut Karlson is working on batteries wrapped in a thin photovoltaic cell- meaning that these batteries charge when simply left out in the sun!
I'm still not sure about the level of "green" associated with using batteries, but rechargable solar batteries sound like a potentially feasible option to me for many of the small power consumers around the house- decentralizing seems to me to be the way to go for relaiability in the case of alternative energy sources. Conter-arguments?
