Silent and ultra-efficient wind turbine Liam F1 Bashny.Net

 





And although it is increasingly common to see solar panels on the roofs of homes, household wind turbines are still a fairly rare sight. If the technology company The Archimedes from Rotterdam will be able to prove the viability of its development and possible domestic landscape will change soon. On 27 may, the company officially introduced its Liam F1 turbine, Urban Wind Turbine, which, they claim, has a power output of 80% of the theoretically possible maximum. That's a pretty bold statement, considering that most commercial wind turbines have a capacity of, on average, 25 to 50 percent of the technological maximum.

The turbine has a weight of 75 kg (165 lb), diameter of 1.5 meters (5 feet), and clearly looks like a typical windmill. In form it resembles Nautilus and the screw pump invented by ancient Greek mathematician Archimedes of Syracuse.





This form factor reportedly results in minimal mechanical resistance, allowing the turbine to rotate freely and silently — it is the noise from the blades is a major obstacle to the installation of turbines on the roofs of buildings. In addition, the turbine is designed in such a way that is always in the wind, to get the maximum result.





Along with his promise that the turbine is able to reach 80 percent of the limit of Betz's law, Archimedes company States that The Liam F1 generates an average of 1,500 kilowatt-hours of energy per year at wind speed of 5 m/s, which is a half of the power consumption of the average household. Needless to say, will be interesting to see what it says independent testing. The company claims that it has tested The Liam F1 50 more times, to confirm the effectiveness and have already sold the 7,000 turbines in 14 countries.



Wind turbine, according to the creators, will be significantly more efficient than most existing wind turbines

However, wind turbine Liam F1 Urban Wind Turbine will be officially available for sale only from 1 July. However, the price is already known — on the official web-site of the company is the announcement that the cost will be €3999 (about $5450).
