Has anyone had any contact with a person or had any experience with vertical axis wind turbines? They are so much 'easier on the eye' than a wind tower.

Do you know anything about cost?

I have been trying to find any type of rebate/incentives for solar in Wyoming, but so far have found none. Is there a 'national' incentive? I want to seriously look at full/partial solar /wind, but at this point cannot afford to make my world better- it is just too costly!

Thanks
