What It Is /// WePOWER is a vertical-axis wind turbine that operates quietly and performs well in low-speed winds. How It Works /// Unlike many turbines, which either rely solely on lift (in the case of traditional three-blade turbines) or drag (used in wind-speed gauge anemometers), WePOWER uses a combination of both.
Vertical-axis wind turbines (VAWTs) have experienced a renewed impulse during the last few years with important research efforts focused on them. This work explores whether the global profitability of VAWTs can be improved through improved manufacturing techniques.
Over the past few decades, due to extensive use of fossil energy sources, world is facing global warming and increasing greenhouse effect. Higher need of energy and less accessibility to power supplies requires the use of renewable sources of energy like wind-energy, which is most prominent for suitable applications.
The technology for traditional horizontal axis wind turbines (HAWTs) have been in development for more than a hundred years. This technology includes blades and their manufacturing, gear boxes and their manufacturing technology, pitch angle devices and their technology, and so on.
In the design process of a vertical-axis wind turbine it is crucial to maximize the aerodynamic performance [22, 26]. The aim is to maximize the annual energy production by optimizing the curve of the power coefficient varying with the tip speed ratio .
