I had thought about maybe using several sets of blades to run one geared up motor faster and hopefully still have plenty of startup torque in low winds.

What I would like to eventually build is a wind gennie that looks like an airplane. Either twin engine or 4 engine. The problem I have is I don't want all that weight of motors way out on the wings like that, would have to add to much support and wings be too thick etc..

Supporting blades and preventing twist in the wings would not be much problem, perhaps belt/chain drive to a couple alternators mounted in the body at the tower would solve the problem. Each side would have 2 blade sets to  spin them fast geared up for low speed blades, and a motor like a tread mill could provide the juice to excite them all?

For this idea, alternators are pretty light weight. If using 4 100 amp ones and getting 50 amps each that's 200 12V amps or 2400watts from one gennie and one tower. I would be happy with that, anything more would be great.

For controlls I think the rudder to guide it into the wind like the tail normally does. To furl I had a couple thoughts. Offset the weight of the gennie a bit forward, design in a little lift on the front wings but not much so only high winds have any effect and also use the tail wings to tip it up in high winds. I have seen gennies on here that used lift up furling before I think, instead of side turning. This would be the same tilt up idea.

Something I am thinking about, would like to do, but not working on! Would be happy to look at pictures of anyone elses if they build one like this :)

I think it could be a good but maybe complicated design that would have lots of bennfits.
