The OLPC Afghanistan team rigged up this pedal-powered generator for the OLPC. Using the generator from their Freeplay hand crank, the system is set up so that students can actually generate enough electricity to power the computer while they are using it.

It’s a pretty simple setup, but seems to make sense in this context. Anyone want to set up a ‘green’ coffeeshop filled up with these things? [via neatorama]
