Magic hub: Generator + 145 Tandem + 48 hole + Freehub rear?

Question for the gearheads out there: I'm trying to replace the cheap rear freehub that came with my Hase Pino. Ideally it would be 40 / 48 spoke for fully loaded touring, and spaced at 145 to fit the dropouts (I think).

If possible though, I'd like to get some electricity out of this as well - the Pino comes with wiring pre-fit in the frame, and the coil of wire on the chainstay taunts me. Are there any dynamo hubs that fit the rear of a tandem?

The last alternative is to get a bottle generator, but I hear those suck.

Sturmey Archer used to make a variety of dynohubs, possibly including what you want, but finding one would be tricky and the old magnets tend to get weak... so not a very good solution. Something modern is not so easy.

But look for a Panasonic / Spanninga hub dynamo; I got one on ebay a few years ago, and use it on my xtracycle. It's a donut shaped dynamo that attaches to a conventional rear hub, ideally one with 36 spokes. It's quite powerful.

Modern Bottle type dynamos do not suck as they did several years ago. Paired with tires with dynamo tracks molded in the sidewall provides reliable operation in wet conditions. Snow and Ice would render it useless. The advantages are; no drag when disengaged, easily replaced, low cost, and no one is going to steal it.
Have you considered a Bottom Bracket type Dynamo?

It mounts where a kickstand would be and is operated with a lever attached to the seat tube using standard bicycle cables.
