The One Laptop Per Child project is demonstrating the Pedal Power Machine. The desk with pedals is designed to run students’ computers when electricity isn’t available. The desk has a pair of pedals that can be used to charge an OLPC. If I had to pedal everytime I used one of my notebooks I’d probably be in good enough shape to compete in the Tour de France.
According to OLPC Afghanistan, the contraption is easy enough for a third grader to operate. The organization hopes that the Pedal Power Machine will aid in the deployment of OLPCs beyond the existing power grid in Afghanistan and elsewhere. A video demo is available here.
