TreeHugger.com: CES 2009: PowerFilm's Battery Chargers and \$1,000 Solar Blanket

    Before I knew which way to point my thumb, I would want to know the useful lifespan of the product. The price doesn't mean that much without knowing how long it will last.

    I think $80 for perpetual AA cells seems pretty reasonable. While camping, you could just lay them out by your tent during the day.

    Hmmm, follow your links back yourself. The 60W powerfilm is about on a par with the cost of the only other solution near 60W in your list (55W listed for about $1K). The powerfilm offerings are packaged for rugged use and fold to conveniently packable brick sizes. Their accessory line is quite good if not really cheap. If all you're charging is AA and AAA batteries, these expensive chargers are a waste of time. If you want to run/charge a Macbook, 60W is barely sufficient ;-) ... their chargers are rated for 60W. At that point you need something worth quite a lot of dough.
