Low Environmental Impact & Cost Effective

• Begin with market and SoA evaluation• Look at historical VAWT Challenges• Low blade speed (2.5x wind) 35-40%

efficient• New extrudable blade design extensively

hydro/aero tested• Use modern design/analysis tools

Low Environmental Impact & Cost Effective

• Computer modeled complete system including turbine/electronics/mechanics

• Designed for: low noise, ease of installation, pleasing visual appearance

• Five prototype units built now, Three in transit to LBL – culminates a 2 year effort

• Next Step - Testing 20-25 in various environments in the next year

• Certified, Market ready in ½ to 1 year
