Power Scheme for OLPC Project Falling Into Place 126
robotrachel writes "According to Technology Review, the $100 laptop intended for children in the developing world will be powered in much the same way that you might start an outboard motor on a boat. The new power system will 'make the laptop much easier to power than it would be with a hand crank, in part, because the users will be able to operate the generator in a variety of ways, including holding the device (the size of two hockey pucks) in one hand and pulling the string with the other, or clamping the generator to a desk, attaching the string to one foot, and using leg power.'" There are plenty of sewing machine treadles in the world, too -- I hope someone can figure out a way to combine them with the new design.

Doubtful. Solar is not cheap. Last I recall PV is still around 3.5-4 USD per watt. At a 20 watt target that'd cost you about 70-80 bucks. Not a good cost for a 100 USD laptop. This device is supposed to cost ~10 USD. From solar you'd only be getting 2-3 watts or so for that price.

I wouldn't say that a human powered generator is exactly free. Humans need substances called food and water. These substances are often scarce in the areas which this laptop will be used.
IMHO, this laptop project is a great idea. Food will keep you alive but education gives power. Both are needed in developing nations. Perhaps this project will help a student design an irrigation system which will increase the potential of a crop.
