<P>PROBLEM TO BE SOLVED: To increase kinetic energy of an air flow, and to convert it into mechanical energy. <P>SOLUTION: A rotor-type super windmill based on logarithmic spiral-shaped load-bearing elements represents a single block of two vertical rotors having invertedly curved load-bearing elements, and produces, in the rotary mode, in the inter rotor space, circulation of velocity of both rotors in one direction, and ensures summation thereof with the velocity of the air flow. <P>COPYRIGHT: (C)2012,JPO&INPIT |
