Current Energy Market
ƒ Renewable energy account for 3% of U.S. electricity mix
ƒWind accounts for 50%
ƒ Current wind energy technologies are limited by:
ƒ Horizontal/vertical wind products
ƒ Limited to locations, require high winds, high cost
ƒ Limited power production, inefficient
Horizontal Axis Turbines
ƒ Limited locations
ƒ Usually on a 30-100’ pole mount – Higher is better!
ƒ Requires large fall distances
ƒ Must reorient to changing wind directions
ƒ High maintenance costs

Vertical Axis Turbines
Darrieus (lift) vs
vs. Savonius (drag) based systems
Darrieus machines
ƒ First patented in 1927
ƒ High tip speeds
ƒ Difficult to mount on high poles
ƒ Typically cannot self start
ƒ Higher power output greater efficiency
ƒ High vibrations

Vertical Axis Turbines
Darrieus (lift) vs
vs. Savonius (drag) based systems
Savonius machines
ƒ Rotor is an “S” shape
ƒ Spin close to the speed of the wind
ƒ Low start
start-up
up wind speeds
ƒ Lower efficiency and power output
