Anybody tried a chain driven generator?

    Your link did not work but I have heard that some of those bicycling generators don't last long. And I remember as kid I had a couple and they did not work very well.

    But, I thought about using the racing alternators that we use in our race cars. That's as far as I have gotten is just thinking about them. They are pretty small.

    if you use a car alternator it would also have to be low amp <30-35amps

    I'd love to find a charging system for these little engines. For just running lights may only need 20 amps. Most on autos are for 60-100+ amps.and are heavy. Most small engines I've found have stators and rotors built in internally like motorscooters and motorcycles. I've looked for a small external alt. to chain drive to no avail. An automotive alternator also must spin a 2-3k rpm for peak output.
    Any ideas?

    I know a few of us are working on a solution. I'm doing it slowly, and I know Creative Engineering is as well, but I don't know what kind of progress he's made.

    Here's an alternator for a 50cc MODEL AIRPLANE engine. If it's for a small battery like a power wheels battery you find at the Wal marts next to the bicycles that should do quite well!

    Alternator / Generator on a 50cc Gas engine.

    It's rather small enough that you can almost use a rubber band!
    But it really should be enough maybe?
