COAXIAL ROTOR WINDMILL AND METHOD OF INCREASING KINETIC ENERGY OF THE FLOW

摘要

Coaxial rotor windmill along with its simplicity differs from all other similar devices in that it is capable, without attracting outer energy but only due to the peculiarities of its structure, to increase initial natural wind velocity and, consequently, kinetic energy thereof as well as in view of a high conversion efficiency exceeding considerably the analogous rate of all the known devices of this kind to convert this kinetic energy into mechanical rotary energy.
