A debate over whether it is best to harness wind energy with horizontal-axis devices or vertical-axis devices has raged for thousands of years. Even how the technologies evolved is under some dispute.

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 ...

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% ...

BRIMFIELD — It is a bumpy drive from the house to the top of the hill, where the family of David L. Cheney established an apple orchard more than 100 years ago. At it's peak, the orchard spanned 65 ...

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 ...

Wind energy researchers are re-evaluating vertical axis wind turbines (VAWTs) to help solve some of the problems of generating energy from offshore breezes. Sandia National Laboratories' wind energy ...

Think of wind turbines and massive blades spinning above Kansas prairies or off Danish coastlines are probably what comes to mind, but Minnesota-based Janulus has developed something a little more ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American The vision is beautiful, if not somewhat ...

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 ...

Research carried out by Oxford Brookes University has found that vertical turbine designs could make large wind farms more effective. In the study, the researchers compared traditional wind turbines ...

January 29, 2009 While wind turbines are a clean, green way to generate power, they can be a bit of an eyesore and require quite a bit of room meaning, more often than not, they need to be located in ...
