This paper summarizes the development of vertical axis wind turbines based on the Darrieus rotor. A performance analysis was developed which permits the estimation of the characteristics of such machines; 5 m high wind turbine using curved wooden blades was fabricated and tested. The tests confirmed the low starting torque of the turbine and wind tunnel tests were performed on model Savonius rotors to determine optimum starter bucket configurations. Finally, a straight-bladed turbine was constructed, concluding that Darrieus turbines should be useful in large systems used to generate electrical power for the grid; for direct water pumping purposes, however, these turbines are unlikely to be suitable.
