Underwater kite can harness the ocean’s power for sustainable energy
The Swedish company Minesto is making waves in the renewable energy sector with its innovative Dragon 12, an underwater kite that promises to generate clean electricity.
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.

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 figures to play a pivotal role in this plan, complementing existing wind, solar and hydroelectric power sources.

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.

Founded as a spin-off from aerospace giant Saab, Minesto has perfected its technology since 2007. With 92 patents and a successful track record, the company’s utility-scale tidal power plant, Dragon 12, delivers electricity to the Faroe Islands’ grid.
While the Dragon 12’s innovative design offers many advantages, questions remain about its long-term reliability and impact on marine life. As Minesto continues to refine its technology, the answers to these questions will shape the future of tidal energy.
As we stand on the brink of a renewable energy revolution, companies like Minesto are in charge of technologies that could redefine how we harness the power of nature. The Dragon 12 is more than just a machine; it symbolizes human ingenuity and our relentless pursuit of a sustainable future. With its potential to provide clean, affordable energy, the Dragon 12 could be a game-changer for communities around the globe.
