Ive heard about a new wind turbine that starts up and runs at very low wind speeds. Would it be a benefit if a windmill started up at lower speeds?
The conventional answer was no, since the energy available in the wind is a function of the cube of its speed, there is very little energy available to be harvested at wind speeds less than 4 meters per second (m/s) (9 mph). Also historically low speed wind turbines would not produce as much energy at rated wind speed (optimum wind speed). However Master Flo has developed a new style of wind turbine (patent pending) that starts producing energy at lower wind speeds and produce the same amount energy at rated speed. So Master Flo Vortex has a more efficient design that uses the wind speed more efficiently. Therefore if you are considering the purchase of a wind turbine, the ability to start at lower wind speeds should be consideration factor in selecting a machine, but the most important factor is power it can produce over a year. If a turbine can start producing power at lower wind speeds and produce more power at all wind speeds it will generate more power per year.
