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% ...

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 ...

The awareness of a greener future and its benefits is getting all the right attention in Europe. With the current climate conditions and with energy bills skyrocketing, every other person in the ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
