Or look at this picture http://www.rnp.org/images/const4.jpg I can imagine those widely spaced skinny bladed turbines stopping a lot of wind - NOT. They could have got the same amount of power as they get from ten of those from just ONE vertical axis sail based turbine of the same tower height. AND spaced them right next to each other, all along the same path, and got ten times as much energy from the wind.
