Airfoil Design for a Vertical Axis Wind Turbine

With the depletion of fossil fuels, increasing emissions, and the inevitability of global warming, the interest in renewable energy grows. Conventional solutions, like horizontal axis wind turbines, are reaching the limits of their capabilities. Therefore, there is renewed interest in other models, such as the Vertical Axis Wind Turbine (VAWT). While there are multiple variations on the VAWT, the most viable one is the Darrieus turbine, patented in 1932 (Darrieus, 1931). This turbine operates on the principle of aerodynamic forces acting on vertically placed blades, spinning around an offset center. When enough torque is generated, power is produced. The advantages of this configuration are that it is easily scalable, will not suffer from gravitational loads and ha...

A Floating Wind Farm

With a focus shifting towards global sustainability, more effort is being put into improving the efficiency of renewable energy technologies. Wind energy is a predominant area of interest and now it takes on a new twist.   In July 2015, we published an article on the different ways to make a wind turbine float. Many pilot projects have been conducted to test which ones were the most effective. Statoil was the first company to makes significant strides in the area, and now that they have refined their design, a new project is about to set sail.   The Hywind Park has recently been approved to develop the world’s first, and largest, floating wind farm. The ocean off the coast of Scotland will soon be welcoming five floating six-megawatt turbines, anchored 24-35km from la...
