Wind turbines are a great way to offer alternative energy for consumers. However, the beauty about wind turbines is that they can be easily improved to offer better serve our energy requirements and it looks like the DARWIND5 has done just that over in Ontario, Canada.
The DARWIND5 is a vertical axis wind turbine (VAWT) designed by Harvistor, something which reportedly improves the usual delivery of old wind turbines. As per recent tests, the DARWIND5 can achieve 35% more kilowatts per year over the usual VAWT while operating at 25% lower heights as well.
Harvistor says it approached the DARWIND5 design like F1 racing, with performance boosted by a new type of rotor blade telemetry and geometry. This translates into new airfoil shapes, which allow the rotor system to completely avoid power-robbing dynamic stall, a reaction that occurs when airfoils rapidly change the angle of attack.
