Abstract: Wind Sail Turbines end the fossil fuel age and supply abundant, clean, and very inexpensive electricity (power). The new Wind Sail Turbines produce roughly 10-Fold to 50-Fold more power than existing wind turbines in the same wind path. This patent has the effect of replacing most of the science that is the basis of current Wind Science and current wind turbines. This patent changes the scientific understanding of how to effectively utilize wind and/or water flows to produce energy. Rotor blades, wings, and sails etc. are not airfoils working primarily from lift. These 3 devices are sails that work due to wind collisions. Therefore, sails are newly defined scientifically by the application of the New Wind Power Formula.
