Wind energy technology has taken an innovative leap forward with the introduction of a tree-like wind turbine that combines aesthetics, functionality, and sustainability. Developed by the French company New World Wind, this groundbreaking design makes renewable energy accessible in urban settings and even private backyards.
The “Wind Tree” Concept
Dubbed the “Wind Tree,” this novel turbine is constructed from an array of micro wind turbines called “Aeroleaves.” Each Aeroleaf is equipped with advanced technology, including copper-wound stators, synchronous permanent magnet generators, and optimized controllers. The tree structure can host up to 36 Aeroleaves, achieving a maximum power output of 10,800 watts.
Standing just under 10 meters tall, the Wind Tree is designed to seamlessly integrate into urban environments or residential areas. Its installation takes only two to four days, making it a practical option for anyone seeking to harness wind energy.
Efficiency and Performance
Each Aeroleaf is capable of generating 300 watts of power. The collective system is fine-tuned by microcontrollers that adjust the rotor’s performance every 10 milliseconds to maximize efficiency, even at varying wind speeds.
The Wind Tree operates in wind conditions as low as 2.5 meters per second and can withstand gusts of up to 50 meters per second. For optimal energy production, average wind speeds of 12 meters per second yield up to 36,000 kilowatt-hours annually, while typical wind conditions of 8 meters per second produce nearly 18,000 kilowatt-hours per year.
Wind Speed Recommendations and Limits
- Minimum Wind Speed: 2.5 m/s (required to start operation)
- Optimal Wind Speed: 12 m/s (maximum efficiency and energy production)
- Maximum Wind Speed: 43 m/s (continuous operation)
- Maximum Gust Speed: 50 m/s (short-term tolerance)
These specifications ensure that the Wind Tree is suitable for a wide range of climates and wind conditions, including urban environments with variable wind patterns.
Key Specifications
- Total Power Output: 10,800 W
- Nominal Power: 5,868 W
- Individual Turbine Output: 300 W
- Number of Turbines: 36
- Inverter Voltage: 110 / 230 V
- Tree Height: 9.8 meters
- Turbine Height: 0.98 meters
- Total Weight (excluding anchoring): 3,590 kg
Adaptability and Scalability
The Wind Tree’s modular design includes additional options like solar panels integrated into the Aeroleaves, further enhancing its energy production capabilities. The tree connects to an energy management system, directing power to a control box equipped with a frequency converter, surge protector, and a battery for energy regulation.
Safety has also been prioritized; the turbine operates at a low voltage of 48 volts, minimizing any risks to passersby. The design allows installation as close as six meters to buildings, making it suitable for tight urban spaces.
Expanding the Concept
New World Wind has extended its innovative approach to include other designs, such as the Wind Palm and the Wind Bush. These variants cater to different energy needs, with capacities ranging from 3.6 to 9.0 kilowatts.
A New Era in Urban Wind Energy
By blending engineering excellence with nature-inspired design, the Wind Tree and its counterparts open a new chapter in renewable energy. They offer a practical, visually appealing solution to energy generation in urban landscapes, making clean energy more accessible than ever before.
This innovation highlights the potential for combining technology and design to address the global energy challenge in a sustainable way. With products like the Wind Tree, the future of urban renewable energy looks brighter—and greener.
