The turbine's inventor, Heinrich Stisald, is small in the shadow of the steel giant's curves, watching workers weld towers that would be contained in the seabed. This Danish countryside factory has churned thousands of masts for wind turbines whose blades can span more than 500 feet. It is an important contributor to the global wind revolution that supplies electricity to millions of homes worldwide.
Soon the factory will set about a new task, the manufacturing component for a different kind of turbine, designed by Stisdal, which bobs on the open sea. These structures promise to place strong, frequent gusts flying over deep water within reach for the first time. Turbines found around Denmark, England, and other coasts of the North Sea are now built for shallow water and require large underwater structures to hold them in place. "Population centers in normal places don't have shallow water - they have deep water," says Stadel, a veteran turbine inventor and a former executive at some of Europe's largest wind companies. This situation makes many coastal areas unsuitable for wind energy.
If the next generation of wind farms can float, and if costs can be kept low, it can usher in an era of virtually unlimited, emission-free energy. The International Energy Agency (IEA) estimates that based on expected power demand in 2040, floating wind turbines can provide enough electricity to meet the world's electricity needs.
At the age of 63, Stisdal has taken every step in the modern development of wind energy. At his younger age, he designed the first turbine, after that he takes participation in the development of the first offshore wind farm, and he makes it one of the best renewable source of energy. They have observed that the global wind capacity in 1978 does not exceed about 600 GW.
As 2019 ended, nearly three-quarters of global offshore capacity arrived in Europe, mostly in the U.K. And was only around Germany. This regional dominance is partly owed to shallow relative to the North Sea. Many more locations, including California, Japan and South Korea, are in great need of electricity, have great ambitions to reduce emissions, and are deep-sea. Not to mention that people complain - loudly — about the turbine within the sideways eyes. The open sea is not in anyone's backyard.
Now Stisdall is among those who build a floating future. With offshore wind power being increasingly competitive with fossil fuel pricing, deepwater expansion could help rid the electric grid of carbon emissions for good. He also said that he has some bad experiences about thinking of climate." he says.
When he completed high school in rural Denmark in the late 1970s, Stisdal heard about a nearby teachers' college that was doing an experiment to make electricity from the wind. He decided to try to build a model turbine in his family home. He made the first blade out of steel and high-grade nylon, working on the living room floor as his mother knitted on the couch.
The first turbine he built was so small that he could lift it with one hand. "Once you were spinning it, it came alive, and you could feel all the little things in the air," Stassdal recalls. "I was hanged." It worked well enough that he got a local machinist to help build a larger version that could provide electricity to his family's farm.
A few years later, with more stabbing, he grew to a point that it took two people to carry a blade. Executives from a local manufacturer of hydraulic cranes came to check his turbine and drink coffee. Even before climate change, replacing expensive, polluting fossil fuels with air had become a pressing concern.
Tisdale entered into a licensing agreement with the authorities, which eventually led to mass production and later a full rebranding as the Vestas Wind System A / S. The company is the world's largest wind turbine manufacturer, having more than $ 13 billion in revenue last year. In its official corporate history, Vestas acknowledges that its initial efforts - designed to look like an oval - failed to produce enough electricity to be viable. But Stiesdal's prototype, the company writes, "is essentially the three-bladed model used today." And not only by Vestas: the same configuration is used by scores of manufacturers worldwide.
