Aerolift Patent BV is the inventor of the patent protected Venturi Wind Turbine (see above picture on the left).
Conventional windturbines create a diverting windflow through the turbine.
The result is that the theoretical maximum efficiency is 59% (Betz law).
Because of its special aerodynamic behaviour, Venturi Wind Turbines, create a windflow pattern that converges first. Wind tunnel studies at the Technical University of Delft in 2003, have demonstrated that a two blade Venturi Turbine has a measured efficiency of 79% and a three blade Venturi Turbine has a measured efficiency of 85%
This break through technology has many advantages:
*attractive design and styling
* high acceptability in urban area’s
*high output in low wind conditions
*efficient and cost effective design
*firm construction, high reliability
This unique aerodynamic concept has been patented worldwide.
