The Alaskan Brewing Co. is going green, but instead of looking to solar and wind energy, it has turned to a very familiar source: beer. http://phys.org/news279387691.html Technology Wed, 06 Feb 2013 16:00:01 EST news279387691 (Phys.org)—ESA research has helped to develop an aircraft-grade alloy that is twice as light as conventional nickel superalloys while offering equally good properties. The path to creating this alloy required research under all types of gravity. http://phys.org/news271408318.html Technology Tue, 06 Nov 2012 07:12:30 EST news271408318 A new development from Siemens makes it possible for operators of electric arc furnaces to obtain electricity from hot exhaust gases. Around 20 percent of the electricity required to melt steel scrap could be recovered with the method, according to a report in the latest issue of the research magazine "Pictures of the Future". Up until now, it has been very difficult to carry out such a process because of temperature and gas-volume fluctuations. Siemens therefore developed a salt storage unit that acts as an energy buffer between a steel furnace and a turbine. The first pilot facility for the system went into operation in the German state of Thuringia in mid-April 2012; the first system product is scheduled to be manufactured in 2013. http://phys.org/news258628727.html Technology Mon, 11 Jun 2012 11:20:01 EST news258628727 (PhysOrg.com) -- Solar cells, the heart of the photovoltaic industry, must be tested for mechanical strength, oxidized, annealed, purified, diffused, etched, and layered. http://phys.org/news238751898.html Technology Tue, 25 Oct 2011 09:00:05 EST news238751898 If you think it's tough to make Baked Alaska or a delicate soufflé or some other temperature-sensitive dish in your kitchen at home, imagine the painstaking task of trying to cook to perfection 250 miles in the sky -- where you can't even peek inside the oven. http://phys.org/news231595725.html Space & Earth Wed, 03 Aug 2011 13:30:04 EST news231595725 A new process developed by Siemens cuts the energy required to recycle steel and also lowers carbon dioxide (CO2) emissions. http://phys.org/news183743354.html Technology Tue, 26 Jan 2010 16:00:02 EST news183743354 The U.S. Department of Energy should consider gradually changing its system of setting appliance energy-efficiency standards to a full-fuel-cycle measurement, which takes into account both the energy used to operate an appliance, as well as upstream energy costs -- energy consumed in producing and distributing fuels from coal, oil, and natural gas, and energy lost in generating and delivering electric power. This change would offer consumers more complete information on household energy consumption and its environmental impacts, says a new congressionally mandated report from the National Research Council. http://phys.org/news162642806.html Technology Wed, 27 May 2009 11:34:33 EST news162642806 When Larry and Lauri Kraft decided to add a great room and three-season porch to their 1959 split-level home in St. Louis Park, Minn., they chose "green" remodeling to protect their children's health. http://phys.org/news154962454.html Technology Fri, 27 Feb 2009 13:08:46 EST news154962454 With steelworks around the world emitting huge amounts of carbon dioxide, scientists are reporting that a byproduct of steel production could be used to absorb that greenhouse gas to help control global warming. The study is scheduled for the October 15 issue of ACS' Industrial & Engineering Chemistry Research. http://phys.org/news143112914.html Chemistry Mon, 13 Oct 2008 10:35:14 EST news143112914
