EPFL researchers developed optimal pitch profiles for vertical-axis wind turbines using a genetic learning algorithm. The new pitch profiles resulted in a 200% increase in turbine efficiency and a 77% ...

The Eiffel Tower has just unveiled a new, sustainable facelift, and perhaps the most striking update to the famous landmark comes in the form of two of Urban Green Energy’s (UGE) vertical axis wind ...

Small vertical axis wind turbines (VAWTs) possess the ability to effectively operate in the presence of high turbulent flow, which makes them ideal energy harvesting devices in urban and suburban ...

Even as more offshore wind projects launch and the turbines they use get bigger, there are questions around offshore wind’s economic viability. Unsurprisingly, hauling huge equipment with multiple ...

If you’ve got a property with some outdoor space and plenty of wind, you might consider throwing up a windmill to generate some electricity. Indeed, [The Broject List] did just that. Only, his ...

As fish swim in a school, they generate power in their wake that other fish can share. When a researcher at CalTech realized that the model could be duplicated for ...

A modern day windmill that is good for the environment and your wallet. Sept. 16, 2010— -- Moving to alternative energy reduces our dependence on foreign oil, but it is not always easy or ...

Windspire's VAWTs individually perform similarly to all vertical axis turbines, at levels of efficiency below that of horizontal-axis wind turbines. They have struggled in the relatively crowded small ...

Researchers at the UK’s Oxford Brookes University think wind turbines would be more efficient if they were designed differently. A team from the School of Engineering, Computing and Mathematics has ...

These scale model wind turbines use fixed-pitch blades to evaluate a new vertical axis wind turbine design. Vertical axis wind turbines are easier to install than traditional horizontal axis wind ...
