Wind Tunnels Show Terrain Affects Wind Farms
Iowa State engineers are using wind tunnel tests to study the effects of hilly terrain and turbine placement on power production. Hui Hu pulled a model wind turbine from the top of an office filing cabinet. The turbine tower was just 10 inches high. Its three blades were 10 inches in diameter. It was a perfect 1:320 scale reproduction of the 80-meter diameter wind turbines spinning across Iowa, the country’s second-ranked state in installed wind power capacity. That mini turbine is helping a research team led by Hu, an Iowa State Univ. associate professor of aerospace engineering, understand how hills, valleys and the placement of turbines affect the productivity of onshore wind farms.

Tickell Talks (from the director of Fuel and The Big Fix)
TICKELL TALKS Sundays at 12noon PST / 3pm EST
Listen to Josh as he interviews experts in the fields of advanced fuels, solar energy, wind, new energy technologies, biotech, eco-agriculture and green chemistry as well as automotive experts, finance experts and the people who are building a new generation of green industrial processes for everything from making drinking spirits greener to greening our schools and hospitals.
The driver of the show is simple – it’s the bottom line. Every week, every subject is tied to money saved, and money made. Don’t think Green is a big money maker? Well, Bloomberg cites cleantech as over a $250 Billion dollar a year industry – that’s Billion with a “B.” And it’s growing exponentially. So whether you agree with the green ethos or you want more green in your pocket, listen to TICKELL TALKS Sundays at 12noon PST / 3pm EST.
