Wind turbines without blad
It is a prototype, but still very little, because the experimental phase is nearing completion. According to experts, "Tornado", the first example of 'wind farm without blades, within a few months will be installed, work perfectly even in areas where the wind is weak (even 2 meters per second) and become an alternative to contested turbines large blades catch the wind energy that is causing contrasting reactions among environmentalists, landscape designers and entrepreneurs. A Tuscan town, Volterra, has even prohibited their installation in order not to damage the landscape of the village.
THREE METERS IN HEIGHT - 'Like Tornado', designed by a group of Russian engineers and engineered by the "Western co 'company in San Benedetto del Tronto specializes in renewable technologies was presented in Florence in' green jobs' summit on ' alternative energy desired by the leader of the Greens Tuscan Fabio Roggiolani and attended by experts from across Europe. The machine, which is reminiscent of a cone, has the advantage of not having the blades and thus they can be camouflaged better in the environment. An average wind turbine reaches into the twenty, thirty meters, 'Tornado' does not exceed two and three meters in the future will be even more miniaturized. "It works everywhere even where there is too much wind - Roggiolani says - because it is capable of accelerating the air and create a tornado effect good move for the turbines and produce energy. The energy efficiency is higher than that of a normal turbine and cost less than 30%. How does it work? 'The air enters from the base of the cone - meets John Cimini, president of Western co - inside the machine and the flow is transformed into a vortex until, very powerful, it reaches the top of the device where the turbines to generate l' electricity.
PRIME MACHINE FROM 2010 - The tests will be conducted by a consortium of hi-tech companies and toscane Marche in collaboration with the University of the Marche and the CNR of Florence. The first plant will be installed in the Parco dei Monti Sibillini. Then we will move to production. "We hope to build the first machine after the first half of 2010, announces Cimini. But the technological marvels green does not end there. Always at the Florence summit were presented systems to capture energy without polluting the environment. As the mechanics and chemistry platform, developed by engineer Alessio Cianci (Officine Berti), able to exploit the cavitation luminescence dell'acquae and turn it into energy. And yet the "new molecular photovoltaic 'presented by the European Laboratory for Nonlinear spectrometry at the University of Florence in a position, in the very near future, centuplicare of the power of a photovoltaic panel. Almost science fiction research in the Department of Earth Sciences, University of Pisa. Professors Paul Fuligni and Alessandro Sbrana have some plants' cycle track 'capable of transforming the heat of the underground electricity without any extract fluid from groundwater.
