PowerFilm rollable solar-powered battery charger

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.

Prod cost for 1 meter square of efficient solar is around $300; the largest of these rollable ones is half-meter square at over $400. so you pay a premium for rolling it up.

as for efficiency itself: 30 watts per square foot is the rule of thumb these days. this yields 20 watts at 3 square feet. you really pay for a rollup solar panel.

better is a fixed-panel: more efficient and far cheaper. long live jc whitney's!
