Neither the United States nor China, this small country of 50,000 people came up with an idea to create energy from the Moon.
In a remarkable energy innovation breakthrough, the Faroe Islands, a small European nation of approximately 54,000 inhabitants, has pioneered a revolutionary underwater energy system that harnesses lunar gravity to generate electricity. This ingenious approach, developed by the Faroe Islands Space Program in collaboration with several key partners, represents a significant advancement in renewable energy technology that has eluded major global powers like the United States and China.
Lunar-powered underwater technology transforming energy production
The Faroe Islands Space Program has successfully deployed Luna 12, an underwater kite system that captures tidal energy influenced by the moon’s gravitational pull. Unlike traditional approaches to renewable energy, this system operates 60 meters below the ocean’s surface, where it uses controlled trajectories to capture the kinetic energy from marine currents.
The Luna 12 underwater kite, developed by Minesto, generates 1.2 megawatts of power—enough to supply approximately 200 homes with electricity for a year. Following a four-month testing period in the North Atlantic, the system has been successfully connected to the Faroese electrical grid, marking a world-first achievement for this innovative design.
Martin Edlund, CEO of Minesto, envisions a future where this technology extends far beyond the Faroe Islands: “Our system has the potential to be deployed at more than 3,000 sites worldwide, offering a reliable and sustainable energy solution powered by lunar forces.” This ambitious vision could help address global energy challenges while minimizing environmental impact.
The underwater kite moves at speeds approaching 30 km/h, utilizing the same principles that allow NASA scientists to map nearly 100,000 underwater mountains – the predictable patterns of ocean currents affected by gravity, topography, and planetary forces.
Engineering challenges of subsea energy systems
Creating technology that functions reliably in harsh marine environments presents numerous engineering challenges. Luna 12 operates in corrosive saltwater conditions with significant pressure, experiencing sudden accelerations and substantial forces that would quickly damage conventional equipment.
SKF, a Swedish engineering company founded in 1907, played a crucial role in developing the critical components for the kite’s steering system. Yvonne Rydberg, an engineer at SKF, participated in designing the watertight bearings essential for the system’s operation. Her primary focus was preventing water intrusion into critical areas, which would otherwise lead to corrosion or reduced efficiency.
The development team utilized advanced simulation tools like SimPro to model potential stresses and anticipate challenges before they manifested as actual problems. This proactive approach to engineering has resulted in a robust system equipped with real-time performance sensors capable of detecting wear and alerting operators before any failures occur.
The environmental forces that Luna 12 must withstand are similar to those that cause small earthquakes in the Alps due to global warming – the constant pressure of natural elements against human-made structures requires exceptional engineering solutions.
| System Component | Engineering Challenge | Solution Implementation |
|---|---|---|
| Steering Mechanism | Saltwater corrosion | Specialized sealed bearings |
| Structural Frame | Pressure at 60m depth | Reinforced composite materials |
| Tethering System | Current forces and tension | Dynamic stress distribution design |
| Control Electronics | Water infiltration | Hermetically sealed casings |
Faroe Islands: small nation with ambitious renewable goals
The Faroe Islands form an autonomous archipelago belonging to the Kingdom of Denmark, comprising 18 volcanic islands situated in the North Atlantic Ocean between Scotland, Norway, and Iceland. Despite their small population of approximately 54,000 inhabitants, the Faroese have set an ambitious target of achieving 100% renewable energy by 2030.
This lunar-powered underwater kite project involves three key partners:
- Minesto – The designer and developer of the Luna 12 system
- SKF – Swedish engineering firm specializing in bearings and sealing systems
- SEV – The Faroese energy company responsible for grid connection infrastructure
Their collaboration aims to transform the Faroe Islands into a showcase for renewable energy innovation. The next phase of the project targets the development of a 200-megawatt installation capable of meeting 40% of the islands’ electricity needs, demonstrating the scalability of this technology for broader global implementation.
The project reminds us that sometimes the most powerful innovations come from unexpected places, similar to how the brain can influence intestinal bacteria through unexpected pathways – small systems can create significant impacts.
Global potential of lunar-influenced tidal energy
While several nations have explored tidal energy generation, the Faroe Islands’ approach represents a unique methodology. France’s EDF operates the La Rance tidal power station with 24 Kaplan turbines producing 240 MW, one of the world’s oldest and largest tidal power plants. South Korea has also developed innovative tidal projects utilizing hydroelectric turbines to capture marine current energy.
What distinguishes the Faroese approach is its lightweight infrastructure and innovative deployment method. Unlike traditional tidal installations requiring massive fixed structures, Luna 12’s kite design offers flexibility and reduced environmental impact, while still capturing the powerful forces created by lunar gravity.
According to Minesto’s estimates, the global potential for currents that could be harnessed using this technology reaches approximately 650 gigawatts—exceeding the current worldwide installed nuclear power capacity. Unlike nuclear power, which has generated interest in missions like China’s Tianwen-2 asteroid sample return, this technology produces no waste and requires no fuel.
The power of natural forces should never be underestimated, as demonstrated by events like the 1960 Valdivia earthquake in Chile, the most powerful ever recorded. Similarly, the moon’s gravitational influence creates predictable, powerful energy sources that can be harnessed without the risks associated with technologies like those that led to the Starship 36 test explosion.
The Faroe Islands’ pioneering work demonstrates that innovation can emerge from unexpected places, potentially reshaping our approach to renewable energy on a global scale through harnessing the ancient relationship between Earth and its celestial companion.
