The goal of this project is to build and test a kite powered electrical generator. Kites are being deployed successfully for powering large ships weighing 440 tons over long haul distances of nearly 12,000 miles.The success of these projects stems from the fact that the kite provides for a very large force and the ship provides the required displacement to produce power.If the ship were to stay stationary no power would be produced and the kite will follow a complicated figure eight motion to dissipate the wind energy. Extracting the energy out of the kite when the generation facility is stationary has stymied the researchers due to the fact that inevitably any stationary objects attached to a kite will run out of string, kick starting acomplicated (figure eight motion) under the kites own inertial forces where control is untenable.

For as long as kites have existed, researchers and investigators have known the force of the kite and have failed to produce any useful work out of its force.

We propose a dual kite model. A small kite and a larger kite are deployed together. The function of the smaller kite is to constrain the motion of the larger power producing kite under depowered condition. A diagram of the proposed mechanism is provided.The mechanism consists of two kites attached together. One will act as a Pilot kite (green)and the other as Power kite (red) The function of the smaller pilot kite is to restrict the motion of the larger power kite under the depowered condition so that the kite lines may be reset to the starting position where the red kite is powered again.Both kites are let out under power condition to allow them to gain altitude and get a fly wheel with high moment of inertia going. At the point the kite runs out of line the sensor switch activates the linear motor (depowering actuator) to depower the power kite. The inertia of the rotor is adequate to draw back the smaller pilot kite with the depowered power kite in tow. The linear motor is again activated and pulls back on the control lines to repower the power kite. The four steps of the cycle is clearly marked and shown in the schematic.

The advantage of the system described herein is that a true cycle is established and the process may continue continuously.
The cycle above satisfies all of Diehl’s conjectures
• That the kite will be flying at low angles.
• That lift control plays a crucial role.
• That the kite will be pumping rather than turning a carousel.
• That the connection to the ground will be with one line.
The advantage of this design over all other drag translators is that a continuous true power cycle is achieved. Whereas other researchers who have attempted the problem are all stymied by the complexity of motion and have sufficed their studies to sporadic and incremental power production.
