Well, a few years ago there was a band doing a tour on bicycles in South America, if I remember correctly. They did have some tyre-rubbing dynamo setup for creating electricity, and the audience could volunteer. I did not find the blog post, but ISTR they wrote that the biggest savings were gained by using the bicycle for transportation, not by using it for producing electric power. Sure, you can easily charge an Android phone from a nominally 3-watt bicycle dynamo hub. I once rode some 60km (40mi) and got the battery fully charged when it is completely empty. For powering a bigger device from a stationary bicycle, I guess you would have to use a different setup, such as connecting a generator via belt drive to the rear wheel. Then you could use a Shimano Nexus 7 rear hub, so that it would be Nexus 7 powered C= computing. :-) Best regards, Marko Message was sent through the cbm-hackers mailing listReceived on 2012-08-15 14:00:25
