It looks like Dave posted the link back in March... (see below)
Looks like and interesting idea for some of the reasons already posted. You can put the prop in clean flow to one side or another of the keel. You can retract the generator (eliminate the drag) whenever you don't need the power.
Mark, Since you saw it at the show, do you have idea of what one of these units costs? Even if it's a 12V or 24V unit, it will give an idea of what the manufacturing and marketing costs are.
