Didn't we talk about this, oh, 5 years ago? It would be nice, but I bet it doesn't catch on.. We are *so* deap-rooted to the notion of bringing stinkin' batteries with us everywhere...
PowerFilm have created a roll of solar material that allows one to recharge cellphones, cars, and other rechargeable electronics with a rollable solar panel. They’re made by Iowa Thin Film Technologies and are available in three sizes with varying power outputs. The largest, at 12 x 73-inches, will put out 1.2 Amps and only weighs 1.9 pounds. Available connectors include cigarette lighter, battery chargers, and daisy chain connectors. Prices start at about $150. MMmmm. Sun juice.
