• Purdue engineers test effects of fire on steel structures

    Building fires may reach temperatures of 1,000 degrees Celsius, or more than 1,800 degrees Fahrenheit; at that temperature, exposed steel would take about twenty-five minutes to lose about 60 percent of its strength and stiffness; Purdue researchers experiment with ways to make steel more fire-resistant

  • Militants kidnap 7 from Nigerian Exxon platform

    After the 9/11 attacks, Bin Laden boasted that he used an operation which cost al Qaeda $500,000 to finance to inflict a $500 billion damage on the U.S. economy; this was not a mere boast: experts say it was an indication that econo-jihad was an integral part of al Qaeda’s strategy to weaken and defeat the West; the recent BP disaster offered an example of one tactics terrorists may pursue in order to inflict serious economic and environmental damage on the United States and other countries: attack off-shore oil rigs: these rigs are utterly vulnerable to attack, and the damage such an attack can do is considerable; in Nigeria, a militant organization is already attacking oil rigs — if, for now, only to kidnap rig workers in order to blackmail their employers for money and political concessions; the ease with which such attacks are carried out should give all of us a pause

  • The U.S. rare-Earth industry can rebound -- over time

    Rare-Earth elements are not that rare; the U.S. has plenty of the metals that are critical to many green-energy technologies, but engineering and R&D expertise have moved overseas; responding to China’s near monopoly, companies in the United States and Australia are ramping up production at two rich sites for rare earths, but the process will take years

  • Norway looking to osmotic power generation

    Water-based energy generation conjures up pictures of towering hydro-electric dams, submerged tidal turbines, and bobbing wave-energy converters; the energy embodied in moving water — which all of these technologies exploit — is one way to make electricity from the sea, but it is not the only one; in Scandinavia, a pilot power station is demonstrating that another of the sea’s defining characteristics, saltiness, could also be harnessed to provide electricity

  • Sea-based energy could supply 50% of Europe's needs by 2050

    By 2050 Europe could get up to 50 percent of its electricity needs from renewable marine sources; marine renewable energies include harnessing the power of offshore wind, waves, tides, and ocean currents as well as exploiting salinity and temperature gradients and using algae for biofuel production

  • One in five global businesses affected by growing water shortages

    Experts say that by 2030 global water demand would outstrip supply by 40 percent; a new survey reveals that we do not have to wait that long: drought, shortages, flooding, and rising prices are already damaging companies in water-intensive industries

  • China to push sea water thousands of miles inland

    Chinese officials say they have a found a solution to uninhabitable deserts of Xinjiang in west china: pump raw sea water thousands of miles from the coast to fill Xinjiang’s dried-up salt lakes and desert basins in the hope that it will evaporate and encourage rainfall over drought-stricken areas of northern and northwestern China; the sea water would be carried through a pipeline made of plastic and fiberglass; water experts have condemned the proposal

  • GWU earthquake simulator helps engineering prepare for the real thing

    George Washington University laboratory’s “shake table” — a $1 million, 10-by-10-foot metal structure that moves in six directions — replicates earthquakes and allows engineering students to test construction materials to see how they hold up under tremors of varying strength

  • New Orleans levee committee uneasy with Corps of Engineers modeling

    The Army Corps of Engineers uses complex computer models for hazard analysis calculations on which billions of dollars worth of repairs and improvements to the federal hurricane levee system are being based; the members of the regional levee commission want their own expert to scrutinize these computer models

  • Day of using nuclear fusion to generate power from sea water nears

    New X-ray imaging capability developed at Sandia National Laboratory may help remove a major impediment in the worldwide, multi-decade, multibillion dollar effort to harness nuclear fusion to generate electrical power from sea water

  • Research to help reduce coastal flooding

    According to the Environment Agency’s Flooding in England Report, one in six homes in the United Kingdom are at risk from flooding, and 2.4 million properties are vulnerable to coastal/river floods; coastal areas could be saved from the misery of flooding thanks to new research from the University of Plymouth

  • U.S. military looking for sturdier, more survivable UAVs

    The U.S. military is looking for sturdier, more survivable UAVs; the military regards the airspace over Pakistan and Afghanistan as “permissive environment” — and it wants UAVs to be able to do their work in what it describes as “contested airspace”

  • Oil will run dry before substitutes roll out: study

    At the current pace of research and development, global oil will run out ninety years before replacement technologies; the authors of the new study say the findings are a warning that current renewable-fuel targets are not ambitious enough to prevent harm to society, economic development and natural ecosystems

  • Two nuclear reactors shut down Sunday because of problems

    Two nuclear reactors — Indian Point nuclear power plant, about twenty-five miles north of New York City, and Vermont Yankee nuclear power plant in Vernon, Vermont — had to be shut down Sunday; Indian Points was shut down because a transformer caught fire, and Vermont Yankee was shut down because radioactive water began leaking from one of its pipes
