Abstract
There are disclosed method and apparatus for the production of electrical power from high altitude winds. A kitecraft (12) secured to a ground tether (14) supports a cylindrical drum (10) rotatable about a horizontal shaft (60). The drum comprises a plurality of wheels (24) interconnected by airfoils (26) positioned about the cylindrical surface of the drum. Wind action on the airfoils rotates the drum about the horizontal shaft and turns generators (50) to provide electrical power. The kitecraft (12) and drum (10) assembly is constructed to the maximum practical extent from tension members to reduce weight.
