Gaudencio A Labrador: United sail windmill. July 12, 1988: US04756666 (12 worldwide citation)

This windmill provides low cost energy out of the wind in the form of compressed air, etc, by maximizing wind-contact at the least cost of construction and maintenance, at the least cost of project site--making the "Output/Cost Ratio" very high. This is done by making the sails very large using ligh ...
