And most modern bicycle lamps are now LED, so the standard 6V 3W hub
generator can now produce a lot more light at the same power, or the same
amount of light with power left over to charge a battery. So the
incandescent lamp model is already obsolete, unless you insist on dealing
with antiques.

I did point this out also, just change to LED, and you've "loosened
up" enough juice to charge an added battery.
Remember my post upon return from lunch at Ra, where I looked over a
modern bicycle parked there?

Looks like modern bicycle lights run on 2 AA or 2 AAA, for
_100_hours_!
So. If you have a hub (or otherwise) dynamo, you'd need to regulate
down to 3V, which, if the Magdowski model is remotely correct,
improves the available current and makes the regulation (and charging
control) easy... actually overkill.
Perhaps Larkin will grace us with an actual working solution? Why
don't you lurkers DEMAND he put up or shut up? But you won't. Sad.

I love to cook with wine. Sometimes I even put it in the food.
