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% ...

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 ...

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 ...

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 ...

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 ...

Researchers model optimal configurations of vertical axis wind turbines and find they can offer a future where electricity costs are lowered, or even eliminated, in urban and suburban areas WASHINGTON ...

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 ...

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

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 ...

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 ...

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 ...
