In two weeks I'll be living in Edmonton Alberta. I don't know what zone a sycamore is but I may be able to find one there.
Speaking of sycamores, when I was googling for info on single blade turbine(of which there is no info available) I found this site.

Makes me feel like I'm not that crazy after all. Note the specific reference to low speed performance. That's always been my target zone and I'm confident my maple blade will display exellent low wind speed performance as well as better high speed performance than a conventional rotor with comparable low speed action.
