Researchers at Fraunhofer-Gesellschaft have built a new type of steel blade for wind turbines formed from a 1.0 mm steel sheet and featuring integrated, folded reinforcement. Today’s wind turbines use very large rotor blades made with fiber-reinforced plastics that are almost impossible to recycle. But steel blades recycling ability exceeds 90 percent. Plus they cost […]

Vortex, founded in Spain by three men whose co-founder scientist David Yáñez, has developed a wind power generator without a turbine with wing blades. The Vortex generator uses vorticity, a word formed from the activity potential of a vortex. A vortex can be seen where water twists around going down a drain, in the air […]

University of Washington researchers show in a new study that perovskite material contains flaws that can be engineered to improve solar cells and other devices even further. A new study published online in the journal Science by the University of Washington (UW) and University of Oxford researchers demonstrates that perovskite materials, generally believed to be […]

Researchers at Brown University Institute for Molecular and Nanoscale Innovation have come up with a new way of making thin perovskite films for solar cells at room temperature. In just five years of development hybrid perovskite solar cells have attained power conversion efficiencies that took decades to achieve with the top-performing silicon semiconductor materials used […]

Researchers at Queen Mary University of London (QMUL) have successfully created electricity-generating solar-cells with chemicals found the shells of shrimps and other crustaceans. The materials chitin and chitosan found in crustacean shells are abundant and significantly cheaper to produce than the expensive metals such as ruthenium, which is similar to platinum, that are currently used […]
