Power Density, through an optimized understory, is The New Shape of Wind Energy. We can more than double the output (and more) from existing onshore wind farms.
Vertical Axis Wind Turbines (VAWTs) are the key to Power Density: we can’t do it without them.
Wind Harvest International’s 70kWh VAWT and its coupled vortex positioning patent is the state-of-the-art for VAWTs.
2x+ power can be generated from many existing winds farms
How can the power producer double his output on this existing farm?
4 Siemens 2.3MW HAWT = 9.2 MW
Add in rows of counter-rotating WHI 70 kWh Turbines to existing farm.
4 Siemens 2.3 MW HAWT = 9.2 MW
45 WHI 70 kWh Turbines = 3.15 MW
45 WHI 70 kWh Turbines = 3.15 MW
45 WHI 70 kWh Turbines = 3.15 MW
Total Production: 18.65 MW
WHI Turbines have a Competitive Levelized Cost of Energy ($.08-.11/kWh)
Wind Power Density = MW/Acre or Square Meters
Horizontal Axis Wind Turbines (HAWTs) preclude close proximity.
Increased Power Density occurs with Vertical Axis Wind Turbines
Turbines (VAWTS) are MORE efficient the more closely spaced they are.
