Pedal Powered Generator

I wrote about this ages ago in the Greening, and it's good to see someone hase been doing it (since 1976!). It'd be great if something like this could be commercially available with the relevant accessories to be able to integrate it into domestic usage...

Posting with a bit more detail and a few more links here.
