Hi v.m.

The 'blades' will be attached to the deltas that you see on the extremities of the arms
It will be constituted of two bambou 'masts' and a sail of very light tissu(I have some  parachute tissue)The resulting 'blade' will be a delta of about 3m high (10') and 40 cm wide (1.4 foot) in the middle(level of the arms).
With a rotordiam of 1.40m (4.7 foot)  the height of 3m seems extreme,but I hope reducing the weight of the blades to the extreme it will be safe,without dangerous vibrations,and for a vawt a very good rpm/torque ratio.

cheers,
Jaap
