How It Works
Today’s Grid Storage
The largest machine in the world
2.3% of U.S. total production capacity (24.6GW)
Today’s Grid With WindWind currently
accounts for 5.7% of electricity generated.
Wind power comprised 43% of all new U.S. electric capacity additions in 2012
Wind power is currently the fastest-growing source of electricity production in the world.
Wind Power Problems
Wind speed is not constant
Transmission distance
Birds
Wind Power Benefits
No fuel cost
Operating costs are minimal (mostly maintenance)
Zero air emissions.
Storage ProblemsFour challenges to widespread storage:
1. cost competitive 2. reliability
3. simple integration4. safety
The batteries cannot take the unsettled power outputs and consumer demands.
Storage Benefits Stored energy increases the economic value of wind energy.
Remote energy storage at wind would compensate for gaps in supply.
What can change?Jeff Gates, “The perception is that this stuff isn’t real.. A whole generation of utilities people have grown up with the notion that it’s not reliable, too expensive and it’s 20 years away.”

Future Wind Power
Airborne Wind Turbines
Makani
Altaeros
Wind Harvester
Wind Lens
Eco Whisper Turbine
Vertical Axis Turbines
Windspire
Eddy Turbine
Manmade Island Wind Battery Concept
Makani Wind Turbines
Altitude of 1,000 feet
85% can have access to wind energy as opposed to 15%
Can fly out and quadruple the US’s total wind capacity
Altaeros Wind Turbines
Harnesses High-altitude winds
Reduces energy costs by up to 65%
Helium filled balloons with a turbine in the center
Wind HarvesterCopies motion that uses horizontal aerofoils similar to those used on aeroplanes.
Noise free electric power generation
Can also operate at higher speeds
Wind LensesJapanese turbines that are 3 times as efficient
Claimed to be cheaper than Nuclear energy
Vertical Axis Turbines
30 feet tall and 4 feet wide
6Db above ambient
Produces 1.2kW (~2000kWh at 11 mph wind average)
Eddy TurbineCan withstand 120 mph
Cut-in wind speed of 3.5 m/s; Cut-out of 30 m/s
Generates 600 watts
Eco Whisper Turbine
Virtually Silent
20kW generation capacity
Allegedly, more efficient
Manmade Island Wind Battery
ConceptThe wind power generated by the turbines pumps water into the island and uses gravity to push the water out when energy is needed.
