Wind will be asked to blow into a tube
Wind - an excellent and environmentally friendly source of electrical energy, however, and it has several disadvantages. One of the key - windmills has to have an open area, away from the end user.
Why not put a dozen other conventional wind turbines in the city? Many times after trying to install on the roofs of tall buildings. However, the result is uneconomic - because each wind turbine is designed so that it is always «keeps his nose to the wind», that is automatically oriented in space parallel to the direction of the wind, put a few pieces close «battery» impossible - very limited space. Set whether such installation at a distance from each other, say, on the roofs of various buildings, inefficient: it requires an advanced infrastructure, collecting energy in the total substation.
Situation is not much better situation with so-called «tube» - high cylinder with holes that do not require constant rotation, converting wind energy into electricity, regardless of its direction. However, this type of installation requires very little space.
This second concept has recently been a very shrewd and effective way to improve a group of engineers from the University of Saint Louis in Missouri . The author's ideas - a Hindu by birth Sridhar Kondurov.
First, inside the pipe may be placed in anything - in the production of energy involved only «coil», consisting of many thin tubes. You can literally put this device on a pipe from the fireplace, radio tower, whatever. If you increase the prototype many times, you get a very powerful source of energy, and does not require a complex infrastructure - the transformer is built right into the base of the pipe and collect wind from any number of sections, which, depending on the length of the module can be up to several dozen.
When the wind blows this construction, it picks concentric slits air currents, just as float captures slices of cheese or carrots when the product is scratching its surface. Wherever the wind was blowing, located on one side catchers drive the flow of air in the system of tubes, where the air velocity is sufficient to produce electricity in scale. Do not want no more free space, or an abundance of cables, no separate booth for the transformer. Author patent hopes that with the help of his invention can also be masking the ugly industrial towers, turning them into fancy colored tubes.
Summary
While Western cities, municipalities have agreed on production first, trial shipments novelties, jokers to one of the forums has already proposed a coupled system of a generator and several conventional windmills: pipe to generate electricity, which will be immediately activated at windmills, so that these «mill» blowing against the wind and deploy on the border of clouds and birds from unfriendly nations.
