Swiss researchers boost efficiency of vertical axis wind turbines
Vertical wind turbines could produce more electricity if optimised with tweaks identified by Swiss researchers. As they are quieter, require less space and are less dangerous for birds, such vertical wind turbines could compete with conventional models in the long term, the Swiss National Science Foundation (SNSF) announced on Wednesday. Vertical wind turbines have been around for some time. However, their development has faced challenges in terms of physics, according to the SNSF. As their axis of rotation is perpendicular to the wind... Читать дальше...
