The term “hydroelectric power” often brings to mind immense operations driven by purpose-built infrastructure such as dam systems and large turbines with traditionally metallic, propeller-based ...

Turbine blades for use in jet engines need to be made of a hard, unyielding exotic material made to exact specifications, which means the drilling of tiny cooling holes in the blades runs the risk of ...

MELBOURNE -- Fred Sundermann, an Australian farmer with a long history in design and innovations, has developed a bi-directionally low-head water turbine designed to maximize operational efficiency in ...

ANNAPOLIS, Md. (AP) -- Bumpy whale fins are the inspiration for a new turbine blade designed by Naval Academy researchers that holds the promise of generating electricity from the tides. The blade was ...

Wind turbines attached to floating buoys can harness stronger, more sustained winds in the open ocean. But the floats now used for such deep-water installations may prove prohibitively expensive ...

Composite materials are ideal for producing wind turbine blades because of their strength, light weight, and ability to be tailored to provide the precise mechanical properties needed for any blade ...
