The late professor Thomas E. Sweeney of Princeton University proposed the concept of vertical-axis wind turbines driven by drag/lift force in 1973. The authors fabricated Twisted-Sweeney type wind turbines, based on the Sweeney type wind turbine, to improve the performance and to enhance its external appearances. From experimental testing of this wind turbine in a wind tunnel, the following conclusions were deduced.
