Will Vertical Turbines Make More of the Wind?

• http://www.technologyreview.com, By Kevin Bullis
 The remote Alaskan village of Igiugig—home to about 50 people—will be the first to demonstrate a new approach to wind power that could boost power output and, its inventors say, just might make it more affordable.

For decades, the trend across the wind industry has been to make wind turbines larger and larger—because it has improved efficiency and helped lower costs.

John Dabiri, a professor of aeronautical and bioengineering at Caltech, has a heretical idea. He thinks the way to lower the cost of wind power is to use small vertical-axis wind turbines, while using computer models to optimize their arrangement in a wind farm so that each turbine boosts the power output of its neighbors.
