Wind turbine with record-breaking rotors

Siemens has produced the world's longest rotor blades for wind turbines. Measuring 75 meters in length, the blades are almost as big as the wingspan of an Airbus A380. Beginning this fall, the B75 rotor blades will be installed ...

Stone Age tools help modern manufacturing

Innovative research by the National Physical Laboratory (NPL) and the University of Bradford used laser microscopes to explore how stone tools were used in prehistory, and the process has helped streamline surface measurement ...

Electricity in the air

(Phys.org) -- The faster a wind turbine's blade spins, the more energy you can get from it. And the farther you get from the hub, the faster that part of the blade is traveling. So the tips of the blades generate most of ...

Naturally adhesive

Until now most adhesives have been manufactured from petroleum-based materials. However, they can also be obtained from renewable raw materials -- for example from proteins, natural rubber, starch, or cellulose. Fraunhofer ...

Lab helps engineers improve wind power

A laser in Iowa State University's Wind Energy Manufacturing Laboratory scanned layer after layer of the flexible fiberglass fabric used to make wind turbine blades.

Researchers build a tougher, lighter wind turbine blade

Efforts to build larger wind turbines able to capture more energy from the air are stymied by the weight of blades. A Case Western Reserve University researcher has built a prototype blade that is substantially lighter and ...
