1. A mastless vertical axis wind turbine, the mastless vertical axis wind turbine comprising:
a first plurality of sails configured to rotate about a vertical axis under the influence of wind;
a platform configured to:
couple the first plurality of sails to a first stationary support that is configured to remain stationary as the first plurality of sails rotate under the influence of the wind; and
be in tension with the first plurality of sails at one or more points about a first end of the first plurality of sails and to rotate with the first plurality of sails under the influence of the wind;
a second plurality of sails having respective first ends that are coupled together and second ends that are each coupled to one or more stationary surfaces, the second plurality of sails configured to remain stationary while the first plurality of sails rotate under the influence of the wind; and
a central connector configured to couple the first plurality of sails and the second plurality of sails to a second stationary support.
