Counter-rotating wind turbines (CRWTs) represent an innovative paradigm in wind energy conversion, employing a dual rotor mechanism in which two coaxial rotors spin in opposite directions. This ...

(Nanowerk News) Wind energy is one of the most promising renewable energy resources in the world today. Dr. Hui Hu and his group at Iowa State University studied the effects of the relative rotation ...

The conceptual breakthrough of counter-rotation, after all, requires the counter-rotating blades to be in line with the right vortices from upstream blades. Schools of fish achieve this by following ...

Ocean X, the world's first dual-headed turbine, with a power rating of over 16 MW, is now operational at the Yangjiang Qingzhou IV offshore wind farm, 43 miles (70 km) offshore Guangdong in southeast ...

Many engineers around the world are developing clean energy solutions in an attempt to curb the ever-growing problem of fossil fuel use contributing to global warming. Now, Bloomberg reports that ...

Power-hungry, fossil-fuel-dependent Japan has successfully tested a system that could provide a constant, steady form of renewable energy, regardless of the wind or the sun. For more than a decade, ...
