An aerial power generation system includes a guide line supported by a support body. Wind driven elements are configured and shaped to provide maximum force from both lift and drag during the downwind phase of operation and minimum force during the upwind phase. The guide lines add stability to the system and provide better control over angular orientation and direction of motion. Power transfer is through one or more tow lines connected from the driven elements to power generation devices on the ground. Another embodiment of the aerial power generation system includes a revolving apparatus and two or more wind powered driven elements connected by tow lines to the revolving apparatus. The method includes changing the driven elements between high and low force configurations for downwind and upwind operation, and flying the driven elements in a selected pattern perpendicular to the tow line.
