Airborne stabilized wind turbines system
First Claim
1. An airborne system for producing electricity from wind energy, comprising:
- a turbine section comprising;
a shaft;
at least one turbine rotatably mounted to said shaft and arranged to rotate when exposed to a wind; and
at least one generator coupled to the at least one turbine, and arranged to convert the rotation of the at least one turbine into electricity;
a lifting section connected to a portion of the turbine section for generating a lifting force to cause the turbine section to be airborne at desire altitude;
an anchoring section connected by a tether to another portion of the turbine section to anchor the turbine section to a base relative to the earth; and
a conductor connected to the turbine section to conduct electricity that is generated by the at least one generator for usage or for energy storage;
wherein said turbine section is constructed such that the center of gravity of the turbine section is approximately in the lowest possible position relative to a substantially straight line between a portion of the turbine section that is connected to the lifting section and the another portion of the turbine section that is connected to the anchoring section, while the at least one turbine is in rest;
wherein the at least one turbine exposed to wind is rotated and causes rotational torque to be induced on the turbine section, that causes an angular deviation of the center of gravity from lowest possible position;
wherein said angular deviation of the center of gravity causes a returning torque that increases with the increasing of the angular deviation; and
wherein the returning torque acts on the turbine section, causing the turbine section to reach a stabilized angular position.

Abstract
An airborne system for producing electricity from wind energy includes a shaft, wind turbines rotatably mounted to the shaft and arranged to rotate independently in opposite directions when subjected to the same wind, and generators arranged to convert rotation of the turbines into electricity. A lifting section includes combination of kites and lighter than air balloons, generating a lifting force that caused the system being airborne at desire altitude. The center of gravity of the system is lower than the center of lift of the system; when the turbines of the system exposed to wind and start to rotate, torques are inducing on the shaft of the system; these torques are balancing each other and the remaining deferential torque being balanced by returning torque that is generated by the angular deviation of the center of gravity from it'"'"'s lowest position, the magnitude of this returning torque, increasing as the angular deviation increased, until the system reach angular stability; electricity is generating and conducted through tether to an anchoring section for usage.
