ALEXANDRIA, Virginia, June 6 -- J. HENCH CONSULTING, INC., Benbrook, Texas has been assigned a patent (No. US 11668278 B2, initially filed May 14, 2021) developed by Steven C. Hench, Dallas, Texas, for "Mastless wind turbine for power generation."
A mastless vertical axis wind turbine that comprises a plurality of sails that rotate about a vertical axis under the influence of wind. A platform is connected to and in tension with the plurality of sails at one or more points about the bottom of the plurality of the sails. Also, an external frame is connected to and in tension with the plurality of sails at one or more points about the top of the plurality of the sails. The external frame itself comprises a plurality of legs that converge above the plurality of sails at a central point about the vertical axis of rotation and extend beyond the path swept by the plurality of sails. A coupling mechanism connects one or more of the plurality of legs to the plurality of sails and allows the sails to rotate about the vertical axis of rotation while the legs remain stationary.
