Pedal Powered Wireless Networked Computer?

Friends of Jhai asks: "An NGO called Jhai Foundation, which is building Internet learning Centers in Laos has enlisted Computer Hall-of-Famer Lee Felsenstein to build a cheap, locally assembled, wirlelessly networked PC and communications system. The current details of the machine are here and the application is here. They are looking for similar systems under way that they might work with or which might be ready for deployment. Anyone have any URL's we can check out?" Great! Now you can get your computing and exercising done at the same time! What other types of technology have people managed to adapt to man-power as opposed to boring ol' AC outlets?
