I've been toying with the idea of bicycle generated power for some time, but have done absolutely nothing about it.... typical :-)
My thoughts are going in the direction of setting up something a little like the cycle trainer pin in H's post, but using it to support the back wheel rim which caould then be used to drive a pulley belt to a 12v car alternator. Gears on the bike will help you find viable load for your legs, and the idea of belt drive is because tyres will eventually perish/ be unavailable wheras a pulley belt could be fashioned from cloth ot even animal hide.
Why an alternator? Because dynamos are hared to find nowdays, also Alternators kick out greater power on average. the snag is taht an alternator requires 12v input, so will be ueselss if you have zero batery power. ( Dynamos generate without any input power)
