When we say “wind farm”, most people are equipped with wind turbines, which we can see in the territory of our republic. Turbines are a powerful source of clean energy that provides cheap and reliable electricity in many areas. The most powerful models can produce enough energy with one turn of the blades to cover the needs of one household for two days.
Despite the undeniable advantages of wind turbines, this solution has a number of disadvantages. We can mention, for example, the impact on the environment, the occupation of the open landscape or the uneven supply of electricity, which is dependent on wind speed and can hardly be regulated. “Pinwheels” too it cannot be installed in cities due to their large size. This is where the “wall of wind turbines” has a chance to apply.
Wall instead of “pinwheel”
American designer and businessman Joe Doucet is behind the idea, which was announced by the Interesting Engineering website. He created a relatively unobtrusive wall with small wind turbines that, according to Fast Company magazine, produces over 10,000 kilowatt hours a year, which is enough to power one house.
At first glance, the published concept looks like a kinetic art installation. The wall consists of a square grid, within which they are located small panels spun by the force of the flowing wind. The exact size and format are not fixed, so various variations of this wall in different dimensions could be used virtually anywhere – for example, next to the highway or on the fence around the building.
In its current form, the wall consists of 25 wind turbines, which are attached to 25 vertical bars, along which square panels are placed. At the moment, it is 2.44 meters high and 7.62 meters wide, but the dimensions can be changed and adapted to your needs virtually arbitrarily.
“Twenty-five-meter bars could be used to line the entire building,” says Doucet. The only challenge is to achieve the right weight ratio to make the system as light as possible. The author of the idea assumes that it will have an aluminum skeleton, which can then be lined with any light material.
Ideal for the city
“Instead of the typical walls along roads and highways, you would have a number of these walls,” notes Doucet, who claims that he is already negotiating with several manufacturers to help him bring the product to market. “With additional wind support from trucks, our highways could take care of all energy needs. “
In the near future, any place with enough space for a 25-meter wall could become a potential source of energy. “There is not much direct sunlight in urban areas for solar energy to work here”, Doucet says, adding that “The wind is always there.”
In recent years, wind energy has become one of the most popular renewables. The wind energy market is expected to exceed $ 180 billion by 2027. In early October, the Biden administration announced its plans to populate the entire U.S. coast with wind farms.
