This is a smaller, cheaper, and efficient successor to the Ene-Farm products of the past; the new product can operate 20 percent longer than the previous model, for 60,000 hours. The developers, Tokyo Gas and Panasonic, said that this Ene-Farm home fuel cell achieves overall efficiency of 95 percent LHV, as the world's most efficient fuel cell. http://phys.org/news278061894.html Technology Tue, 22 Jan 2013 07:25:08 EST news278061894 In some isolated clinics in parts of Africa, the electricity needed to power lights and medical devices is generated by expensive imported diesel fuel; the water supply can be so cold in winter that health workers can’t even wash their hands properly. But a startup company established by a team of MIT students and alumni aims to change that. http://phys.org/news263461201.html Technology Mon, 06 Aug 2012 08:41:28 EST news263461201 The National Physical Laboratory (NPL), along with partners In2Tec Ltd (UK) and Gwent Electronic Materials Ltd, have developed a printed circuit board (PCB) whose components can be easily separated by immersion in hot water. http://phys.org/news257765902.html Technology Fri, 01 Jun 2012 10:38:41 EST news257765902 Is centralized heating an effective way for BC communities to reduce greenhouse gases? http://phys.org/news256543106.html Technology Fri, 18 May 2012 07:10:01 EST news256543106 Clever, inexpensive design can cut the energy used in new homes by up to 80 per cent, says a Queensland University of Technology (QUT) researcher. http://phys.org/news252834245.html Technology Thu, 05 Apr 2012 08:44:13 EST news252834245 Azalea web blight, caused by a species of the plant pathogen Rhizoctonia, occurs each year on some containerized azalea cultivars during nursery production, particularly in the southern and eastern United States. Azalea shoots can harbor the pathogen, spreading the devastating, costly disease through propagation. http://phys.org/news242997888.html Biology Tue, 13 Dec 2011 11:24:57 EST news242997888 Systems to harness the sun's energy typically generate either electricity or heat in the form of steam or hot water. But a new analysis by researchers at MIT shows that there could be significant advantages to systems that produce both electricity and heat simultaneously. http://phys.org/news238403868.html Technology Fri, 21 Oct 2011 08:17:58 EST news238403868 Adding a pretreatment step would allow producers to get more ethanol from switchgrass harvested in the fall, according to a Purdue University study. http://phys.org/news234014482.html Biology Wed, 31 Aug 2011 13:01:36 EST news234014482 Hot water from Newcastle’s geothermal borehole finally gushed to the surface this morning. http://phys.org/news228457574.html Space & Earth Tue, 28 Jun 2011 05:27:07 EST news228457574 For years the only hot water in Zoleka Mali's home came out of a pot on her paraffin stove. http://phys.org/news228325056.html Technology Sun, 26 Jun 2011 16:37:52 EST news228325056 In the battle against soil fungi that discolor horseradish roots and can render the entire crop unsellable, University of Illinois researcher Mohammad Babadoost found that subjecting the roots to hot water before planting was most effective in killing the pathogen in propagative root stocks. http://phys.org/news198766057.html Biology Mon, 19 Jul 2010 14:00:01 EST news198766057 (PhysOrg.com) -- Scientists at Newcastle University have completed the first phase of a giant central heating system that will harness heat from deep underground. http://phys.org/news196533199.html Space & Earth Wed, 23 Jun 2010 17:33:52 EST news196533199 The search for life on other planets focuses on water, but researchers argue that - judging from our own planet - a large fraction of water conditions may be inhospitable to life. http://phys.org/news193665942.html Space & Earth Fri, 21 May 2010 13:05:56 EST news193665942 Carbon is usually typecast as a villain in terms of the environment but researchers at the University of Warwick have devised a novel way to miniaturise a technology that will make carbon a key material in some extremely green heating products for our homes and in air conditioning equipment for our cars. http://phys.org/news177076423.html Technology Tue, 10 Nov 2009 12:10:02 EST news177076423 University of Utah researchers will inject cool water and pressurized water into a "dry" geothermal well during a five-year, $10.2 million study aimed at boosting the productivity of geothermal power plants and making them feasible nationwide. http://phys.org/news171624024.html Technology Tue, 08 Sep 2009 10:21:10 EST news171624024 Mine shafts on the point of being closed down could be used to provide geothermal energy to local towns.
