Yes good reference and after click on wind machines, read: " Wind speed is critical! Double the wind speed, get 8 times the power. The wind is slow and turbulent near the ground and on rooftops. The industry standard is that wind turbines must fly at least 30 feet above anything within 500 feet. " Confirming my statement that power in wind goes as cube of wind speed and that to get to economically useful wind, the new wind machine would need huge expensive steel base as it is mainly a big wind blocker, at the top easy to topple over in stronger, useful winds. The post 3 photo, which I bet is "photo shop" made is not even as tall as the near-by trees seen in the photo! Whole idea silly and not even presented well!
