At last, some reality is perhaps spoken. I rarely, if ever, stick my tuppenceworth in here or elsewhere, but the reality and engineering problems with scale cannot be dismissed and ignored. As I have said elsewhere, a working scale model is all very well, but means absolutely nothing on its own. Scaling up does not increase everything in proportion, eg weight increases by a cubed term, but the effect of the wind in the sails will decrease, as the relative speed will be less.

Its all an interesting idea, and notwithstanding any other doubts I have, eg why was there only one, in the world, ever, the engineering just does not work out.

I wish you well, its a good debate, but the only way to say this works is with a full scale version. With ropes and poles that would be equivalent to ancient ones, ie weak and not straight.

Good Luck.
