Most people will be able to produce a sustained 150-250W of power with moderate effort. Is that enough for your needs?

will that help knock the electric bill down? :)
By a few dollars, maybe...

you need generator or dc motor (dc motors can be run as generators) you may get dc devices at car service centers afaik a dc motor can output about the same watts as it takes as motor - if you spin it in the same rpm

yeah. any instructables on it. or websites that sell complete kits?
you can adapt everything else that uses a generator - like wind turbine projects
