Seagull Wings Inspire High Efficiency Wind Turbine Blades
April 28, 2022 | 1 Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… Open Image…Save ImageOpen Image (using #TmpD/ia)… Scientists from China show a bionic approach combining features of a seagull’s wing to one called a Gurney flap, can greatly improve wind turbine performance. A Gurney flap is an engineered flow control accessory. Combining engineered flaps with the other structures inspired by seagull wings improves lift and reduces stalling in wind energy […]

New Cheaper Platinum Free Hydrogen Fuel Cell Announced
April 26, 2022 | Leave a Comment
Imperial College London researchers have developed a hydrogen fuel cell that uses iron instead of rare and costly platinum that should enable greater use of the technology. Hydrogen fuel cells convert hydrogen to electricity with water vapor as the only by-product, making them an attractive green alternative for portable power, particularly for vehicles. However, their […]

Quantum Battery Charging Cuts Time From Hours to Minutes
April 21, 2022 | Leave a Comment
The Institute for Basic Science said its new technology could make charging electric cars as fast as pumping gas. Quantum charging could cut the charging time of electric vehicles from ten hours to three minutes. The paper explaining the proposed technology has been published in Physical Review Letters. Whether it’s photovoltaics or fusion, sooner or […]

University of Groningen scientists have designed a flow battery electrolyte that is cheaper and is based on an organic compound, rather than a metal. The intermittent supply of green electricity requires large-scale storage to keep our power grids stable. Since normal batteries do not scale very well, the idea of using flow batteries, which store […]
