What is EnerKíte Flight Wind Turbines?
EnerKíte Flight Wind Turbines. Reliable. Economical. Clean. Now invest from €100. This innovative system unlocks the new wind potential with kites. The design takes advantage of high-altitude winds that blow strong and steady, enabling the harvesting of powerful energy that is often out of reach for conventional turbines. Electricity generation is achieved by converting the pulling force of the kite into energy on the ground, where cables and ground stations replace the need for bulky towers and hefty foundations. It is a project that promises to harness the potential of clean, affordable energy using an entirely fresh approach.
Main Benefits and Key Figures
- Double energy yield – Delivering double the annual yield of a conventional wind turbine of the same capacity.
- Resource-saving – Saves 90% on steel and concrete by eliminating the tower and foundation, improving the CO₂ footprint.
- Reduced impact on the landscape – High flight altitude, smaller wing area, and no requirement for massive towers.
- Maximum yield from the air – Every gram saved increases yield thanks to a tensioned carbon rib structure combined with a semi-rigid construction.
- Globally efficient – The systems can be economically operated on about 80% of the land area compared to only 25% for conventional wind turbines.
Electricity Generation and Energy Conversion
The flight wind turbines work with a cyclic generator operation where the wing flies in figure-eight patterns, pulling the cables from drums of the ground station with high force. The rotation of the drums then converts this mechanical energy into electricity. Once the wing reaches the end of the cable, it glides back to the starting height, the cables are rewound with minimal energy expenditure, and the cycle begins anew… This production cycle is both dynamic and efficient, ensuring continuous energy generation even in varying wind conditions.
High-Altitude Winds and Wing Efficiency
High-altitude winds are not only stronger but also more consistent, which is a decisive advantage in power generation. The EnerKíte system capitalizes on these winds blowing at heights of up to 300 meters. The design incorporates an ultra-light wing with a slightly tensioned carbon rib structure, meaning forces are distributed over multiple points on the wing. The outcome is the optimum balance of low wing weight, durability, and good aerodynamics. This approach maximizes energy yield while keeping material usage low, ultimately contributing to reduced operational costs and environmental impact.
Diverse Applications and Market Potential
The technology is versatile and caters to a variety of applications. In the self-supply market, individuals and businesses can generate their own electricity, saving on grid fees while covering the demand for heat and mobility year-round. On a larger scale, utility applications benefit from the lowest electricity generation costs, as EnerKíte can multiply the energy yield of existing photovoltaic or wind farms using the megawatt system. For off-grid areas and islands, the system significantly reduces diesel consumption, cutting costs and bolstering resilience. This mobility and flexibility, tied to a container-based technology that requires no foundations, enable quick setup and deployment even in remote locations.
Flexible, Base-load Capability and Sustainability
EnerKíte offers low-cost electricity by lowering material usage while delivering highly efficient energy generation thanks to the ultra-light wing. Flexibility remains paramount; with an easily transportable, container-based design, the setup is mobile and adaptable. In addition, fixed-base capability is achieved through harnessing steady, high-altitude winds, so energy generation is possible even in light wind conditions. The combination of these factors presents an innovative alternative for creating dependable, clean energy at competitive costs – paving the way for future energy landscapes that are both sustainable and cost-effective…

Milestones and Looking Forward
Since its inception, EnerKíte has achieved several milestones that mark its journey from an innovative idea to a tangible technology. In 2016, the realization of the start and landing system was completed during the first crowdfunding campaign, paving the way for a key component in this advanced kite system. Come December 2021, the technical proof of concept validated the fully automated operating cycle of the system. This included the rotational start, the transition to the harvesting phase, the iconic figure-eight flight, and the smooth retrieval and landing at the mast. Fast forward to 25.09.2022, and the project entered the phase of product development of the EK100. At each step, the technology has demonstrated that even conventional wind power paradigms can be reimagined and improved upon. The design remains future-proof, ensuring that supporters and users of EnerKíte will have a robust solution to address the tense political and climate-critical global situation. The narrative is continuous – a story of innovation, efficiency, and a passionate commitment to a cleaner, greener future.
