EV contactors capable of interrupting high voltage currents
The European distributor for LSIS, Willow Technologies, presents a detailed look at LSIS’ new range of GER series Electric Vehicle (EV) contactors, what they are, why we need them and how they are able to cope with EV motor controller demands in small to medium size vehicles of all types, easily fitting in to confined spaces, capable of interrupting high voltage DC currents repeatedly and interrupting high short circuit currents in an ...
Fraunhofer completes offshore pumped storage concept test
The Fraunhofer Institute for Wind Energy and Energy System Technology said it has completed a four-week test of its Stored Energy in the Sea (StEnSEA) concept. Fraunhofer said it recovered its three-meter diameter hollow sphere from the bottom of Lake Constance on the Swiss-German border, where it had been operating at a depth of about 100 meters. The technology uses water pressure to drive electromechanical pump components within a central tube ...
Compounds could help turn waste heat into electricity
Cage-like compounds called clathrates could be used for harvesting waste heat and turning it into electricity. UC Davis chemists just discovered a whole new class of clathrates, potentially opening new ways to make and apply these materials. A clathrate is basically a cage of atoms with another atom trapped inside, said Kirill Kovnir, assistant professor of chemistry at UC Davis, who led the work, published recently in the journal Angew...
Reusable sponge could revolutionise oil spill and diesel cleanup
When the Deepwater Horizon drilling pipe blew out seven years ago, beginning the worst oil spill in U.S. history, those in charge of the recovery discovered a new wrinkle: the millions of gallons of oil bubbling from the sea floor weren't all collecting on the surface where it could be skimmed or burned. Some of it was forming a plume and drifting through the ocean under the surface.
Satellite imaging helps managing forest fires
An EU team assessed various European satellite imaging systems for use in managing forest fires. All packages met consumer needs, but the project identified five especially applicable tools, while also helping develop future satellite systems. Uncontrollable fires affect forests of the Mediterranean region, causing soil erosion plus economic impacts. Global warming exacerbates the area's natural proneness to fire, hence the problems will onl...
Materials could turn water into the fuel of the future
Researchers at Caltech and Lawrence Berkeley National Laboratory have - in just two years - nearly doubled the number of materials known to have potential for use in solar fuels. They did so by developing a process that promises to speed the discovery of commercially viable solar fuels that could replace coal, oil, and other fossil fuels. Solar fuels, a dream of clean-energy research, are created using only sunlight, water, and CO2.
Explore the future of driverless vehicles
As part of its year-long programme of events exploring how good design makes life in London better, The London Transport Museum is hosting the Driverless Futures, utopia or dystopia programme from 3rd March until 23rd April.
Everything's relative: Renowed genius lends his weight to refrigeration system
The team at SolarCool Energy are drawing inspiration from one of Albert Einstein’s inventions to produce a refrigeration system that even seasoned engineers in the refrigeration industry didn’t believe was physically possible. SolarCool’s Sales Director, Roger Shenton, said how its approach can reduce energy requirements in commercial refrigeration by up to 70%.
Canadian Solar raises $20M for projects in Brazil
Canadian Solar announced that it raised US$20 million to support the development of eligible projects in Brazil, including the 191-MW Pirapora I project in the state of Minas Gerais. The unsecured funding comes from the China and Portuguese-speaking Countries Cooperation and Development Fund, which was formed in 2013 by the China Development Bank and the Macau Industrial and Commercial Development Fund.
Charging corridor built between Oslo, Stockholm and Helsinki
The first High-Power Charging (HPC) corridor will be built by Fortum Charge & Drive between Oslo, Stockholm and Helsinki. The corridor provides charging possibilities for the upcoming models of long range, over 300km, electric vehicles with higher charging speeds. In practice, it means that electric models expected to be on the market by early 2018 will be able to drive from Helsinki to Oslo in the same time as with a conventional car.
