German super wind turbine revolutionizes wind power!
The world’s most powerful wind turbine will soon be built in China. It will have a total output of 16 MW!
A total of 21,000 households are supplied in this way. But a German technology of all things could do this explode values.
The approach, which was tested for the first time in Germany, could be built higher, lighter and more cost-effectively the whole thing is also more environmentally friendly!
We are headed for a world where wind turbines might be taller than 300 or 400m!
This enables wind turbines with over 20-30MW of power.
And that, of all things, through a long-neglected building material, which many probably consider antique or outdated would stamp.
Wood!
A Swedish company now wants to revolutionize wind power technology with wood.
This is already being promoted by Vattenfall and the largest wind turbine manufacturer in the world: Vestas!
The results are extremely promising!
Steel is an absolute miracle material! It has a particularly high strength, stability and firmness in relation on the volume and is therefore indispensable for architecture.
But with wind turbines, this advantage is not relevant at all. The strength per unit volume does not matter.
In fact, wind turbine towers are actually hollow.
There is enough space here to use other, more suitable materials!
One factor is much more relevant, especially for large towers: the strength per unit weight!
And here, above all, the carbon compounds are the front runners. Special substances from the laboratory, to be more precise, Graphene and Carbine even achieve 100 times the strength of steel. The gives us something similar
nature for millions of years! Wood!
Wood is renewable, completely climate-neutral in production, no, it even has a negative CO2 balance, because Carbon is sequestered as it grows and it’s extremely affordable!
The only counterpoint is currently the image. Wood is considered antique, but it is definitely not.
Hardly any other material is as sustainable, has such good strength per weight and is as inexpensive as wood!
The advantages for wind power technology are really considerable!
So-called laminated veneer wood is used in the new generation of wind turbines.
This is a combination of several layers of wood held together by glue.
Wind power modules are made from this material. They are each only 4.5 meters wide and 14.5 meters long.
In this form they can be easily stacked and transported.
Arriving at the installation site, the modules are assembled into conically shaped cylinders and lifted by crane or helicopters stacked on top of each other to form a wind turbine tower!
The fantastic thing: since the elements are so incredibly lighter, extreme heights can even reach the kilometer range to approach, to be reached. The maximum possible construction height of wood is 1.5 kilometers.
Of course, that would also work with metal, but the problem is that there is currently no crane structure in the world for wind turbines to be erected with heights of +300 meters.
With wood, this is no longer an obstacle. We could reach heights of 300, 500 or even 800 meters.
And heavy transporters for wind turbines could also become superfluous. That would make the installation difficult accessible places significantly simplify.
Since mainly gluing and not screwing, drilling or riveting is used, the maintenance effort for the wind turbine is reduced drastic. A total of 50,000 fewer steel bolts would have to be checked during the inspection.
But what are the disadvantages of the technology?
What about the risk of fire or weathering, for example?
Since wood is very dense, the risk of fire is relatively low. Of course, the material burns when exposed to high heat if these is given, conventional wind power technology fails anyway.
You can’t really speak of a disadvantage here.
The situation is similar with weathering. Of course, the wood has to be coated with a protective varnish so that it too really lasts longer, but this is also done on conventional wind turbines to prevent corrosion and rusting.
The material can last 100 years with varnish. But it really isn’t needed for that long. have wind turbines already obsolete after a few decades, since some of them are then no longer profitable at all.
If this is the case, the wood can be recycled. The tower can be dismantled and the material used for other construction projects, perhaps can even be reused for high-rise construction.
The first conventional wind turbine will be installed in early 2023. If so, then most likely we will too can be found in Vestas wind turbines. The sponsor is regarded as a leader in wind power technology!
But the wood concept cannot solve all problems. For example, there is the factor that the material query is currently not available at all obstacle to the sluggish expansion, at least in Germany.
The main problem here is rather political regulations. But a concept could circumvent this in a very elegant way.
Depending on the circumstances, this wind turbine could even be built just 45m from the next house.
In this way, a gigantic area could be developed that, in fact, wind power with storage systems could even cover the base load
could do!
The special feature: The wind turbine rotates vertically and not horizontally like normal wind turbines.
