So, I would *love* to do something like that. But, I love me some light. Are the dynamo headlights out there equivalent, say, to the SSC P7-C driven at about an amp? Most of the dynamo headlights seem rather weak, but I know there are LED ones out there. Seems like the "6V-3W" on the hub implies that all you're ever going to get out of it is 0.5 A, but I don't really know much about power/dynamos.
