Wind power has always been a trade off between clean energy and the visual, acoustic, and ecological cost of giant spinning blades. A new generation of radical designs promises something different, ...

Bionic bladeless propellers, inspired by the effortless movement of jellyfish, are transforming aquatic propulsion. Traditional propellers are noisy, inefficient, and hazardous to marine life, but ...

Insights from a new study could help unlock the full potential of a developing form of smaller-scale wind power generation, researchers say. Engineers from the University of Glasgow have used ...
