What is the minimum wind speed required for KOHILO to generate power?

The “Vortex” will begin to spin at 0.9 MPH and commence electricity production at 2 MPH, considerably less than the cut-in speed of 7-9 MPH of traditional wind turbines. This reduced cut-in speed further diminishes the siting constraints and installation limitations plaguing horizontal axis turbines. The “Vortex” can be installed in any location and does not need to be situated on 50-300 foot towers for optimization. KOHILO’s technology does not need to scale these barriers for optimum performance.
