i can't get the pic to load, but shaft drive: yes, it's been done before, pretty much like every other 'innovation' in cycling. I've ridden a Zero, and it's ok, but it'll never be as efficient as a chain, which is something like 99.9% efficient anyway (dunno the figure off hand, but it's high). Shafts and rubber bands work better (so I'm told, and by Mike Burrows, who should know) on higher speed, lower torque applications, like motorbikes, or machinery. On a pedal bike, a chain really is best, although if you're not bothered about a small loss in effciency, but want low maintenance and no oiliness, a shaft will work. For the average pootling leisure or commuting cyclist (of the sort I'm seeing here in France, or that you see in Holland or Denmark or wherever), it's probably fine.
