Harvard scientists create wind turbine inspired by humpback whale fins, promising 20% more efficiency and less noise.
Researchers at Harvard University have brought an innovation to the wind energy sector, based on a unique characteristic of humpback whales. These sea creatures, with their long, impressive fins, served as a model for advanced marine design. wind turbines. The new technology, which aims to increase turbine efficiency and reduce noise, promises to transform wind energy generation, especially in areas with low winds. The scientists' innovative approach could mark a significant advance in harnessing renewable energy and reducing the environmental impacts of traditional turbines.
Inspired by nature
The humpback whale, known for its imposing fins, has small protuberances called tubercles.
These unique structures play a crucial role in the innovation of wind turbines.
- First 3-meter residential wind turbine, developed with artificial intelligence, is presented as a revolutionary solution to transform the future of renewable energy!
- Billion-dollar amendments favor thermal power plants and threaten to reduce the cost of offshore wind energy in Brazil, putting billions of reais at stake and the sustainable future at risk
- Bill Gates continues to invest in the renewable energy revolution, this time with foldable wind turbines, which are easier to transport and can be assembled 10 times faster than conventional ones.
- World's largest wind turbine is Chinese: China's wind turbine breaks record of 15 MW and generates power for 160.000 homes
Frank Fish, an American biologist, Philip Watts, a Canadian engineer, and Stephen Dewar, a Canadian businessman, observed these bulges and developed a wind turbine design based on the shape of the whale's fins.
Wind Energy Challenges
A the energy Wind power has grown significantly around the world, including in Brazil. However, the generation of this renewable energy faces challenges related to wind variability and noise generated by turbines.
Strong winds are necessary for turbines to work efficiently, but these winds are not constant.
Furthermore, noise generated by wind turbines is a known problem, both mechanical and aerodynamic.
To face these challenges, the Harvard team created a wind turbine that stands out for its ability to operate more efficiently even in low winds.
The innovative design aims to overcome the limitations of traditional wind turbines.
The new technology, known as Tubercle technology, uses the idea of the small protuberances on the humpback whale's fins.
The researchers conducted experiments in wind tunnels, testing model airplane wings and blades equipped with these protrusions.
The results showed that the protrusions improve the aerodynamics of the blades and reduce the turbulence that causes noise.
With Tubercle technology, wind turbines can produce up to 20% more electricity in low winds and with a significant reduction in noise.
This innovation solves two critical problems faced by traditional turbines: low wind performance and noise reduction.
Advancements and recognitions
Since the creation of the company WhalePower, which was formed to develop and apply the tech Tubercle, the team received several recognitions.
Among them, the nomination for the 2018 European Inventor Award stands out.
The invention was not just limited to wind turbines; WhalePower has licensed the technology for other uses, such as industrial and computer fans.
Tubercle technology has been patented and licensed to several companies, expanding its reach to different applications such as marine thrusters, low-flow hydroelectric generation, pumps and compressors.
WhalePower continues to explore new opportunities to utilize this innovative technology.
The future of the wind turbine
A innovation brought by Tubercle technology has the potential to transform wind energy generation.
By improving turbine efficiency and reducing the environmental impact of noise, this technology can contribute to a more sustainable future in energy generation.
The humpback whale-inspired design represents a notable example of how observation of nature can lead to significant technological advances.
