PacWind, a company that creates vertical-axis wind turbines, is promoting its Delta II turbine for both consumer and small commercial applications. The turbine produces 10 kilowatts (kW) at approximately 28 mph and has a cut-in wind speed of 6 mph. Unlike previous designs, this turbine can self-start at extremely low wind speeds and has no need for a braking mechanism. Vertical turbines take up minimal space and are virtually silent, thus making it easy to place multiple units within just feet of one another. The Delta II units can also be stacked vertically up to 50 kW.For product specifications see the manufacturer’s website linked below.
