A kite underwater?

Imagine a kite flying through the air, tracing a figure-eight pattern as it soars. Now, picture that same motion deep under the sea. That’s the essence of the Dragon 12, Minesto’s groundbreaking machine designed to harness the power of ocean currents to generate electricity.

How Dragon 12 is helping to create sustainable energy

Nestled in the North Atlantic, the Faroe Islands have embarked on an ambitious journey toward 100% clean on-shore electricity by 2030. The Dragon 12 is set to play a pivotal role in this plan, complementing existing wind, solar, and hydroelectric power sources.

The science behind the Dragon 12

It generates electricity by harnessing the kinetic energy of tidal currents. Here’s how it works:

Movement: The Dragon 12 is designed to fly in a figure-eight pattern underwater, similar to how a kite moves in the air. This movement accelerates the flow of water over its wings.

Energy Conversion: As the water flows over the wings, it spins a turbine attached to the kite. This turbine converts the kinetic energy of the moving water into mechanical energy.

Electricity Production: The mechanical energy from the turbine is then converted into electrical energy, producing up to 1.2 megawatts of power.

Grid Integration: The electricity generated by the Dragon 12 is transmitted via cables to an onshore station. From there, it’s integrated into the national grid system, making it available to power homes and businesses.
