It turns out that the mass of a Li polymer battery needed to replace the dynamo output for 12h is only about 60% of the excess mass of the dyno hub over a standard lightweight front hub found in typical aero wheels. If your support crew can swap out your battery every day, it's a much better deal than a dyno, even ignoring the 5W of motive power you're losing to generate power.

I'd ditch the dynamo for battery happily.
But then how do you charge garmin/phone/iPod?

A dynamo hub with an aero rim, I guess I'd like to see that.
Do you even audax?

I somehow feel that if you need a light, you don't need an aero rim... unless you plan to do some crazy US Coast to coast race where you do 25 mph on an interstate in the middle of the night, in which case I would ditch the horrible drag of a dynamo hub for a set of batteries... any other scenario seem to exclude one or the other
