Traditional three-blade turbines are great if you have lots of space to play with, but the Optiwind Compact Wind Accelerating Turbine is ideal for high-density, low-wind areas. The turbine’s series of small, five bladed fans funnel in wind and accelerate it, thereby cranking up wind speeds to generate more power.
At six meters in diameter, the Optiwind’s blades are also significantly shorter than traditional turbine blades, which often extend to 80 meters. That means the turbine can be used in areas that don’t have much space to spare, like schools, hospitals, and hotels. Still, potential sites should have 3.5 acres of open land available to comply with local zoning laws
The Optiwind’s design reminds us of the Jellyfish vertical axis wind turbine, but while the 36-inch tall Jellyfish is suited for households, the 200-foot tall Optiwind is meant for bigger structures. Optiwind’s 150 kilowatt model is meant for buildings that use $35,000 of electricity each year, and the 300 kilowatt model works for operations that require $75,000 of energy or more.
