The Windmill has become part of the passage, but it can also become a memory
Don Quixote fought to the windmills in the sixteenth century. The wind has been joining to the wood burning one of main human sources of energy. Not long ago, and even today in a sportsmanlike manner, our ships crossing the seas by the wind; and in everywhere we can find mills which are grinding grain or pumping water.
So history offers us a way to replacement the fossil power station in front of the disaster of global warming; but has several drawbacks as usual with all renewable energies, hence the difficulty imposed on fossil fuels. When I wrote “We must change the way we see energy” I had exposed the difficulty of supply our demand, not only amount of energy and power but punctual peak of them. Another problem is an eco-landscape. The mills are huge blades that rotate at speed relatively slow but relentless with birds that cross the large area covered by them; may appear to be somewhat anecdotal but the reality is that bird populations begin to decrease in area with mills. Another feature of these is that they are due to their large size, breaking the fairing of the mountains and creating malaise with the tourism industry and defense landscape. We currently have environmentalists and environmental movements’ requiring an increase of production of wind energy while other environmentalists argue against in front introduction of each new wind field.
But there are two models of wind turbine: the blades (mill) and the helical. The first is that we normally see in the fairing. The second is vertically mounted helical tube five feet in diameter and up to four meters long. Its small diameter and compact shape makes it very difficult that birds collide with it, so it does not need to be raised from 50 to 100 meters in height giving it much more discretion. One drawback is the large static vanes that generate due to the great speed with these at the ends; this static electromagnetic creates communication problems forcing wind fields put in places far from the centers of consumption. Helical not generate nearly static for their size and are very quiet this allows them to put them anywhere and therefore in the same area of consumption.
Inertia, especially when considering facilities profitable, making models perpetuation without thinking; even if another solution would be more appropriate. The engineer must offer and often the results are given in a short time, and always with maximum guarantees; who hires him does not want any experiment, he gambles his money and has to trust the engineer; the final result is the perpetuation of the known model and ingineer work. Only inertia when it really breaks the classical solution is no longer feasible
In the case Wind helical turbines it has already been doing. In Guangzhou (China) it's building a skyscraper where six helical turbines were installed. In a city can’t put windmills with blades, so they will install helical turbines. If turbines really are able to give the expected energy, it can change our cities skylines of chimneys by helical columns. The wind still has not said the last word.
