About Why did the wind knife generator stop
Instead of using cloth to catch the wind like Prof Blyth and the ancient Iranians, today's turbine blades are built from composite materials - older blades from glass fibre, newer ones from.

The how and why of the fallen turbine at County Tyrone – one of eight at the Screggagh wind farm – is being formally investigated by German manufacturer Nordex. It’s suspected that there was a break with the machine’s brakes, that the blades then span so fast the head became unhinged, and ultimately the whole thing came crashing down.
Harnessing the power of wind is by no means a novel concept. Those little old farm windmills, dwarfed by modern wind turbines, have their roots in the Middle East, where they were used as far back as the 800s. From there the idea spread to both Asia and Europe, and then traveled to American shores with the early settlers.
Within hours of fiberglass from a broken offshore wind turbine washing ashore on Nantucket, clean energy and anti-wind advocates jumped on the story, and two competing narratives took hold.
In previous research, Keith and co-authors modeled the generating capacity of large-scale wind farms and concluded that real-world wind power generation had been overestimated because they neglected to accurately account for the interactions between turbines and the atmosphere.

6 FAQs about [Why did the wind knife generator stop ]
What happened to Vineyard Wind's GE turbine blades?
Blades for Vineyard Wind's GE turbines sit at the New Bedford Marine Commerce Terminal. (Robin Lubbock/WBUR) Less than three weeks out, the story of Vineyard Wind's broken blade isn't finished. Construction and power generation at the project remains halted.
Who invented a wind turbine?
1957: Johannes Juul, a former student of Poul la Cour, builds a horizontal-axis wind turbine with a diameter of 24 meters and 3 blades very similar in design to wind turbines still used today. The wind turbine has a capacity of 200 kW and it employs a new invention, emergency aerodynamic tip breaks, which is still used in wind turbines today.
What happened to a broken wind turbine?
Soon, a picture of the broken turbine itself surfaced. The 351-foot blade had snapped about 65 feet from the base and what remained of it hung slackly, dangling over the ocean. It was not a good look for an industry already struggling against economic headwinds and public concern about its impacts on the ocean environment.
Why do wind turbines fall over?
They are right that sometimes wind turbines fall over, and sometimes (more often) there are mechanical malfunctions that press pause on generation operations. So, it’s worth asking how, how often, why, and is anything being done about it? BBC image of a wind turbine in flames. Fires and fallings over
Do wind turbines deteriorate over time?
You might also ask if deteriorating over time wind turbines produce less energy less efficiently. The answer is yes. Wind turbines usually have a lifespan of 20-25 years and, according to research by Iain Staffell and Richard Green from Imperial College London, see their output (aka how much energy they generate) fall by 12% over those two decades.
How do wind turbines work?
Large commercial wind turbines are the most visible, but you can also buy a small wind turbine for individual use; for example to provide power to a caravan or boat. Wind turbines consist of a set of blades, a box beside them called a nacelle and a shaft. The wind – even just a gentle breeze – makes the blades spin, creating kinetic energy.
