What is an Energy Kite?

When we mention kites, the imagery that typically springs to mind is a colorful, lightweight structure soaring in the sky, controlled by a string held by a person on the ground. While this isn’t an inaccurate picture, the application of kite technology has gone far beyond recreational use, venturing into the realm of renewable energy generation. That’s where the concept of an energy kite comes into play.

An energy kite, also known as an airborne wind energy system, operates on a significantly refined version of the same basic concept of a kite. These energy kites, which can also be referred to as tethered drones or airborne wind turbines comprise lightweight wings armed with wind turbines. With their long tethers, they fly in strong, reliable high-altitude winds, spinning the turbines to generate power, which is then transmitted down the tether to the grid.

The technology behind energy kites represents a paradigm shift in renewable energy generation, providing several notable benefits.

This is usually accomplished through continuous electrical connections, or ‘rings’, made of conductive materials. Common applications for slip rings include wind turbines, radar antennae, and electrical generators, where they effectively resolve the problem of tangled wires during rotation.

As slip rings provide reliable and consistent transmission of electricity while allowing relative rotational movement, their application in the functioning of energy kites is pivotal. Considering energy kites work by reaching great heights to leverage the power of high-altitude winds, their effective operation heavily relies on the ability to maintain free and continuous rotation without compromising electrical transmission.

Slip rings come into play when the energy kite soars and begins to rotate with the wind. They are usually located at the base of the tether connecting the kite and the ground station, ensuring a smooth flow of generated electricity from the soaring kite down to the ground station and subsequently to the grid. They accommodate the continual rotation of the kite that could otherwise tangle a traditional wired system, effectively maintaining a clear path for energy transmission.

Their importance is not just confined to the rotation aspect. As indicated by companies like UEA-inc, Moog, and patents filed on, the specificity of slip rings designed for energy kite applications extends to handling power and data signals. These specially engineered slip rings ensure the safe and efficient transmission of high-capacity electrical power and vital operating data between the ground station and the kite, even under challenging environmental conditions at high altitudes.

In conclusion, the role of slip rings in energy kites is a testament to engineering finesse, solving complex challenges associated with the high-flying renewable energy solution.
