File this under 'green': Voltaic's new Generator laptop bag has a built-in solar panel that can produce 14.7 watts of electricity in a day to charge your laptop. Engadget seems to think that you might bet better off carrying a spare battery because it would be hard to get a full day's sun - and anyway, this beast costs $599.
Likely scenario for laptop bag: a conference. The only time when you wouldn't be lugging your laptop around indoors would be the night, so that's when you'd be able to set your bag down outdoors for 10 hours and let it charge up. Oh - hang on...
But perhaps we should overlook these niggly details, and think about the greater good.
