This innovative wind turbine has two vertical turbines
The futuristic-looking wind turbine comes from Norway and is intended to generate more power in a smaller area. A first prototype will be built by 2026.
The share of renewable energies in the electricity mix continues to increase. As of today we refer about 52 percent our needs from sustainable energy sources, including solar, hydro and wind power. When it comes to wind turbines, however, there is a crucial disadvantage. Because wind turbines influence the air flow. That is why they are usually far apart.
A new concept from Norway now takes a slightly different approach. Because the Norwegian company World Wide Wind presented a new type of wind turbine that has two vertical rotors.
In addition to a relatively high energy yield, the systems can be located in a very small space. The yield per square meter is therefore significantly higher than with previous wind turbines.
World Wide Wind: Two rotors drive a new type of wind turbine
But how is the system structured? At the top of the mast is a rotor. Another is mounted about halfway up the mast. While the upper rotor is attached to a shaft that extends inside the wind turbine, the lower rotor is located directly on the mast.
The generator and the ballast to stabilize the structure are located at the base of the plant. When the wind picks up, the windmill with its rotors should move in all possible directions. The generator then converts the forces vibrating on the construction into electricity. Undersea cables then forward it to land.
Wind energy: New design enables 2.5 times the power
The system primarily benefits from its performance. In addition, it should be possible to build wind turbines with a height of up to 400 meters in order to achieve an output of around 40 megawatts. For comparison: Today’s classic wind turbines generate a maximum of 14 to 16 megawatts.
Since the new wind turbines do not require a gearbox, they are simpler to set up and less expensive to maintain. So far, however, it is only a concept. World Wide Wind wants to develop the wind turbine by 2026 and build a first prototype. This is expected to achieve an output of up to three megawatts.
