A team of specialists in nano-sized rotational motors have directly visualized the process of pumping sodium ions, enabling them to explain why there had up until now appeared to be a structural symmetry mismatch between two motors that make up part of the key protein driving the process. Their findings should help develop a better understanding of the mechanisms involved with cellular energy-conversion motors more generally. https://phys.org/news/2022-10-molecular-motor-specialists-deepen-rotary-ion.html Cell & Microbiology Thu, 13 Oct 2022 08:53:40 EDT news584870017 A pair of researchers at Southern University of Science and Technology, in China has found that when hydroelectric power plants are built, tiger and jaguar habitats are lost, putting the cats at risk. In their paper published in the journal Communications Biology, Ana Filipa Palmeirim and Luke Gibson describe assessing the amount of habitat lost to hydropower and the impact it has on local wildcats. https://phys.org/news/2021-12-destructive-impact-hydropower-jaguars-tiger.html Plants & Animals Fri, 10 Dec 2021 10:10:01 EST news558350377 A team of researchers from the U.S. and multiple countries in South America has found that hydroelectric dams built in the Amazon river basin, which were built to meet the growing electricity demands in the region, are making more of an impact on the natural geography than previously thought. In their paper published on the open access site Science Advances, the group describes using data from satellites to learn more about the true impact of modern dam building. https://phys.org/news/2018-02-hydroelectric-greater-impact-amazon-basin.html Environment Thu, 01 Feb 2018 08:30:01 EST news436690729 Building a $400-million hydroelectric power plant in the world's most arid desert may seem like an engineering debacle, but Chile sees it as a revolutionary way to generate green energy. https://phys.org/news/2015-12-chile-hydropower-plantin.html Energy & Green Tech Thu, 10 Dec 2015 17:48:01 EST news368992074 Residents of a remote village nestled in a steep-sided valley in southern Norway are about to enjoy winter sunlight for the first time ever thanks to giant mirrors. https://phys.org/news/2013-10-giant-mirrors-winter-sun-norwegian.html Energy & Green Tech Sun, 27 Oct 2013 16:25:03 EDT news302109881 Norwegian research scientists will contribute to realising the concept of storing electricity at the bottom of the sea. The energy will be stored with the help of high water pressure. https://phys.org/news/2013-05-storage-power-seabed.html Energy & Green Tech Thu, 16 May 2013 06:15:18 EDT news287903115 (Phys.org) —SheerWind Inc. of Chaska, Minnesota is claiming in a press release that its newly developed funnel-based wind turbine system is capable of producing 600 percent more power than conventional wind turbines. The new design uses funnels to channel wind to a ground-based turbine. https://phys.org/news/2013-05-sheerwind-invelox-turbine-power.html Energy & Green Tech Mon, 13 May 2013 09:30:02 EDT news287655561 Could replacing coal-fired electricity plants with generators fueled by natural gas bring global warming to a halt in this century? What about rapid construction of massive numbers of solar or wind farms, hydroelectric dams, or nuclear reactors—or the invention of new technology for capturing the carbon dioxide produced by fossil-fueled power plants and storing it permanently underground? Nathan Myhrvold of Intellectual Ventures teamed up with Carnegie Institution's Ken Caldeira to calculate the expected climate effects of replacing the world's supply of electricity from coal plants with any of eight cleaner options. The work was published online by Environmental Research Letters on February 16. https://phys.org/news/2012-02-low-carbon-technologies-quick-fix.html Environment Wed, 15 Feb 2012 19:00:05 EST news248544087 Bourne Energy, a company based in Malibu, California, specializes in a variety of hydropower systems. While most of its technology is for large-scale applications, with multiple units generating energy on the megawatt scale, the company recently revealed a hydroelectric generator that is small enough that it can be worn as a backpack. Weighing less than 30 pounds, the Backpack Power Plant (BPP) can generate 500 watts of power from streams at least four feet deep. https://phys.org/news/2010-03-hydroelectric-backpack.html Energy & Green Tech Tue, 02 Mar 2010 14:19:53 EST news186761968 NASA researchers who developed a new way to power robotic underwater vehicles believe a spin-off technology could help convert ocean energy into electrical energy on a much larger scale. The researchers hope that clean, renewable energy produced from the motion of the ocean and rivers could potentially meet an important part of the world's demand for electricity. https://phys.org/news/2009-03-tide-energy.html Engineering Fri, 06 Mar 2009 14:44:29 EST news155572999
