How about a vertical axis wind turbine that would accept air flow from ANY direction without needing to align itself?? Brian Back in the mid 70's the USF had a conference on sail assisted commercial craft. Dick Newick, Myself and 200 others attended with a variety of papers, models and some full size working versions. One craft from the University Engineering Students was a windmill on a cat, driving a prop. Would also go directly to weather. Only thing wrong was it was stepped at the normal mast step (used a sailing cat) and that blade was close to the deck. This was straight mechanical no electric motors or batteries. There are lots of options on motorsailor /power multihulls out there besides the huge solar panels. len Malcolm Tennant wrote: >I must say that I agree with Pat reischmann.

Fletner Rotor ? Cousteau used that on one of his vessels and that hull form was very hybrid cross between cat/tri and sea sled if I remember. brian eiland wrote: >How about a vertical axis wind turbine that would accept air flow from ANY >direction without needing to align itself?? >Brian > > > > > Back in the mid 70's the USF had a conference on sail assisted >commercial craft.
