The most dangerous battery created: 100 MWh of thermal energy and we are going to use it
These are the first diamond solar panels: created out of thin air for futuristic photovoltaic energy
Water is scarce, but we have an even bigger problem: experts are already warning that it will leave us without technology
Photovoltaic energy is getting closer and closer to being the most widely used in America for electricity generation, but is it the only one? A group of experts has just achieved something that was thought to be impossible: this is the world’s largest wooden wind turbine, which they have just turned on without expecting the result: this is what they have started to do and the consequences it will have.
Goodbye to solar concentrators and wind farms: this unique turbine could change everything
Today, it is not enough to simply generate electricity through renewable resources; there is pressure to make everything renewable and even more efficient, and so it came to pass that the world’s tallest wooden wind turbine was constructed in Sweden and measures 150 meters in height.
Constructed with facility by the help of the Swedish start up company Modvion, this structure holds lot of promise in revolutionizing wind power generation. The turbine which has a 2 MW generator has been providing power to the Swedish grid; it is capable of powering 400-450 households.
Such fascinating aspect of the project is the utilization of the wooden construction as a principal material while reflecting the typical trend in the industry associated with steelwork. Although confident in Modvion’s modular kit-house solution, the company’s CEO reputedly smiled broadly and said “It’s got great potential”.
Why to use wood instead of steel? The feature experts have just discovered
Steels have been the most utilized materials for the turbines mainly because of the stability, strength, and reliability in their construction. Albeit, in the light of recent trends that has forced manufacturers to embark on taller turbines with equally large generators, the feasibility of steel has been coming under consistant question.
The difficulties in transporting these enormous steel bodies to the turbine locations have more or less become a main issue, which has restricted the possibility for new steel turbines from attaining greater heights. The wooden turbine towers proposed by Modvion are here to solve this challenge.
Structurally, laminated veneer lumber (LVL) that the company employs is derived from sustainably harvested spruce wood but is equally strong yet considerably lighter. This results in the kind of towers which can be manufactured to higher elevations but at the same time require fewer materials to transport and erect.
20,000 wooden turbines to power an entire country: the details of this colossal project
Sweddish company Modvion is discussed as one of the market’s most promising players for the following reasons. Its long-term strategic vision that is supposed to be achieved no later than by 2027 is that the company is to manufacture 100 modular turbines annually, which can power an entire country like Monaco or Andorra.
The company’s share of the estimated 20,000 turbines that per year are anticipated to be installed is to be 10%. In the second place, despite having had an initially meant tower belonging to the onshore wind turbine family, they seek advancement in developing their technology for supporting offshore wind (as we do in NY).
Since more innovative wind energy is being developed, taller, and efficient, Modvion’s wooden wind turbine technology has the capacity of occupying a valuable position in the world of renewable energy and electricity. This wooden wind turbine is a true representation of creativity alongside technology.
What do you think about what they have achieved with this wooden wind turbine? It is clear that new materials are increasingly necessary, especially to reduce dependence on rare earths. However, the more traditional and natural ones are also a proposal with which we are now going to produce electricity with zero emissions, also during the construction of the generating plants themselves.
