Celcon blocks have been chosen to provide a high level of both thermal and acoustic insulation for a new ‘green’ school, Winston Way Primary School in Ilford, Essex, for Redbridge Council. Celcon Hi Seven and Standard blocks were used for both the internal and external leaves of the building at ground floor level, to infill the Metsec steel frame. With a fully filled cavity the walls achieved a U-value of 0.25W/m²K.
The wait for a complete solar roof solution that blends seamlessly into a tile roof is over. Eagle Roofing Products, a division of Burlingame Industries, announced today the introduction of a comprehensive solar roofing system, the Eagle Solar Roof, to enhance the beauty of any architectural style.
Pacific Gas and Electric Company today announced that it has entered into a long-term, two megawatt (MW) commercial wave energy power purchasing agreement (PPA) with Finavera Renewables Inc. Located off the Northern California coast, the Humboldt County Offshore Wave Energy Power Plant will be developed by Finavera Renewables. The project is expected to begin delivering renewable, clean electricity in 2012.
To ensure a healthy future for all Americans, EPA is off and running in the race to develop a well-trained and diverse environmental workforce. EPA awarded 98 research fellowships in 2007 for students pursuing degrees in environmental studies through the Agency¡¦s Science to Achieve Results (STAR) and Greater Research Opportunities (GRO) programs.
Energy, housing and recycling solutions for the 21st century are among the research topics that will be presented at the TMS 2008 Annual Meeting & Exhibition, March 9-13, in New Orleans, Louisiana, USA. These topics are part of the “Materials and Society” vein of the meeting, which focuses on engineering solutions to some of society’s most perplexing problems.
Researchers at the U.S. Department of Energy¡¦s Brookhaven National Laboratory have unveiled important details about a class of catalysts that could help improve the performance of fuel cells. With the goal of producing ¡§clean¡¨ hydrogen for fuel cell reactions in mind, the researchers determined why two next-generation catalysts including gold, cerium, titanium, and oxygen nanomaterials exhibit very high activity. Their results will be published online in the December 14, 2007, edition of the journal Science.
Carbon emissions from human activities are not just heating up the globe, they are changing the ocean¡¦s chemistry. This could soon be fatal to coral reefs, which are havens for marine biodiversity and underpin the economies of many coastal communities. Scientists from the Carnegie Institution¡¦s Department of Global Ecology have calculated that if current carbon dioxide emission trends continue, by mid-century 98% of present-day reef habitats will be bathed in water too acidic for reef growth. Among the first victims will be Australia¡¦s Great Barrier Reef, the world¡¦s largest organic structure.
The largest living structures on Earth and the millions of livelihoods which depend upon them are at risk, the most definitive review yet of the impact of rising carbon emissions on coral reefs has concluded
In many ways, wind energy seems an ideal energy source. Fields of mighty turbines spinning in rhythm could harness carbonless power and shuttle it off to homes and industries. But questions remain about the feasibility of wind parks: How much will they cost" Can this unpredictable energy source be relied upon to contribute appreciably to the country's power needs"
Scientists have discovered what they think may be another reason why Greenland 's ice is melting: a thin spot in Earth's crust is enabling underground magma to heat the ice.
