Abstract
Abstract This invention relates to a new system for generating electrical energy by wind power. The wind generator is suspended in the air like a kite by wind currents and is attached to the earth by a high strength cable to which are attached electric cables and a natural gas pipe. The numerous small wind generators are mounted in a box-like kite enclosure, which are raised to the desired elevation by rotary blade power with the assistance of a gas balloon. The wind generator kite is raised and lowered to the proper elevation for maximum electrical output. A complete system, including control methods, permits the production of electricity at a lower cost than conventional methods and provides means for generating large amounts of power with a high load factor.
