I am extremely interested (I live on a boat which I built myself [also here in NL!] and I'm trying to make it zero emissions) but sadly I think the rotor diameter of 5 meters is a bit big for me to handle. The weight of 85kg is no problem at all, but the large rotors would be tough to fit on the boat. Would it work with significantly smaller blades (say 1.5m diameter?) and some gearing? The blades are a work of art, so if someone can use the whole thing they'd of course be a better candidate than me. Alternately, I noticed you built a half scale alternator - if you're looking for something to do with it, I'd love to build a wind turbine around that :)
