Pedal power in the desert: OLPC in Afghanistan
It’s still a prototype, but it’s looking promising. The builders have created a pedal power alternative to the hand cranks used on the standard OLPC, and it definitely makes sense to do so. The human body can certainly pedal easier then it can a crank, and the creators of the modification have stated that it’s easy enough to use that a 3rd or 4th grader can power it. Might be hard to type while you’re doing that, but at least you’ll have a full charge.
