The energy kite simulates the tip of a wind turbine blade, the part of a turbine
that makes most of the energy. Rotors on the kite act like propellers on a
helicopter to launch it from the ground station. Once the kite is in flight, air
moving across the rotors forces them to rotate, driving a generator to produce
electricity, which then travels down the tether to the grid.
The tether is made of conductive wires surrounding a high strength core. The
tether connects the kite to the ground station, and transfers power and
communications between the kite and ground station in both directions.
The Ground Station
The ground station holds onto the tether, and is used as a resting place for the
energy kite when not in flight. The ground station occupies less ground space and
is significantly smaller than conventional wind turbines.
