Hey James - off the grid! Nice. You should post up your details.

You're right: it's not going to make a lot of power. Even if I can squeeze 10 amps @ 14 volts out of it (the output of a common car battery charger), it would take forever to completely charge a car battery. Which means I'll only be putting light loads on that battery.

If I ran my laptop from it all day (it pulls about 25 watts, and it's in use for about 10 hours a day on average), I'd then have to ride the bike for about two or 3 hours to replace that energy.
