Mastless wind turbine for power generation

A mastless vertical axis wind turbine, the mastless vertical axis wind turbine comprising:

• a plurality of sails configured to rotate about a vertical axis of the mastless vertical axis wind turbine under influence of wind;
• a platform configured to be connected to and placed in tension with the plurality of sails at one or more points about a first end of the plurality of the sails;
• an external frame configured to be connected to and placed in tension with the plurality of sails at one or more points about a second end of the plurality of the sails that is opposite from the first end, where the external frame comprises:
• a plurality of legs configured to converge at a first point along the vertical axis and that extend beyond a path swept by the plurality of sails, the plurality of legs configured to remain stationary during rotation of the plurality of sails;
• and
• a connector configured to couple the plurality of sails to the external frame at a second point along the vertical axis, where the connector is configured to allow the plurality of sails to rotate about the vertical axis under the influence of the wind.
