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 ...

Dutch startup Airturb has developed a 500 W hybrid wind-solar power system featuring a vertical axis wind turbine and a solar base hosting four 30 W solar panels. The system can be used for rooftop or ...

The type of wind turbine you’re used to seeing in stock photos of wind farms is called a horizontal axis wind turbine (or, HAWT). But there is another form of wind power, called a vertical axis wind ...

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 ...

The now-familiar sight of traditional propeller wind turbines could be replaced in the future with wind farms containing more compact and efficient vertical turbines. New research from Oxford Brookes ...

Norway's World Wide Wind has a radically different take on offshore wind power. These floating, vertical-axis wind turbines feature two sets of blades, tuned to contra-rotate – and they promise more ...

A concept rendering of offshore vertical axis wind turbines (VAWTs). What makes renewable energy so exciting is the immense economic potential of groundbreaking technology advancements. A recent ...

Lower costs, cheaper wind turbines and hurricane safe. That’s the future of offshore wind energy promised by SeaTwirl, a company that makes vertical wind turbines. These new turbines have capabilities ...

Mariah Power, manufacturer of the relatively compact Windspire energy system, has closed the first half of an undisclosed second round of financing (PDF) that it will use to purchase a $2 million ...

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 ...
