AIRBORNE STABILIZED WIND TURBINES SYSTEM
First Claim
1. An airborne system for producing electricity from wind energy, comprising:
- at least one turbine section, each of the at least one 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 arrange to convert rotation of the at least one turbine into electricity;
a lifting section connected to part of the at least one turbine section for generating a lifting force to cause the at least one turbine section to be airborne at a desired altitude;
a tether;
an anchoring section connected by the tether to another part of the at least one turbine section to anchor the at least one turbine section to a base relative to the earth; and
a conductor that conducts electricity that is generated by the at least one generator to an energy usage or an energy storage system;
wherein the at least one turbine section is constructed such that the center of gravity of the at least one turbine section is approximately in the lowest possible position relative to a substantially straight line between the part of the at least one turbine section connected to the lifting section and the part of the at least one turbine section connected to the anchoring section, while the at least one turbine is at rest;
wherein the at least one turbine rotates when exposed to wind and causes rotational torque to be induced on the at least one turbine section, that causes an angular deviation of the center of gravity from its lowest possible position;
wherein the angular deviation of the center of gravity causes a returning torque that increases with an increase of the angular deviation;
wherein the returning torque acts on the at least one turbine section, causing the at least one turbine section to reach a stabilized angular position.

Abstract
Airborne system for producing electricity from wind includes at least one shaft, one or more wind turbines rotatably mounted to each shaft, and generators that convert rotation of the turbine(s) into electricity. A lifting section is connected to the shaft(s) and generates a lifting force that causes the system to be airborne. A center of gravity of the system is lower than its center of lift. When the turbines are exposed to wind and rotate (at least one in one direction and another in an opposite direction), torques induced on the shaft(s) of the system balance each other and remaining deferential torque is balanced by returning torque that is generated by the angular deviation of the center of gravity from its lowest position. A magnitude of this returning torque increases as the angular deviation increases until the system reach angular stability. Electricity is generated and conducted for storage or usage.
