Abstract
A driving apparatus for driving a drive shaft, which includes a number of kites and at least one pulling cable, and means for varying the position of the kites, the kites being arranged to follow an ascending path and a descending path, the kites being connected to the at least one pulling cable, which pulling cable engages a driving element which is connected to the drive shaft, and the means for varying the position of the kites are arranged to impose a first position on the kites in the ascending path in which they are subject to an upward force under the influence of the wind, and a second position in the descending path in which the kites, under the influence of the wind, are subject to a lesser upward force than in the ascending path or even are subject to a downward force.

Wind operable driving apparatus comprising:
- a plurality of kites arranged to follow an ascending path and a descending path;
- a drive element for driving a drive shaft;
- a pulling cable connected to each of said kites and engaging said drive element;
- each of said kites comprising an adjustable control element for imposing a first position on said kites when said kites follow said ascending path and for imposing a second position on said kites when said kites follow said descending path, whereby said kites are subjected to a lesser upward force in said ascending path than in said descending path.
