• Desalinating water, producing hydrogen, treating wastewater -- simultaneously

    Fresh water and reusable energy: humans are on a constant hunt for a sustainable supply of both; trouble is, water purification requires a lot of energy, while utility companies need large amounts of water for energy production; researchers from the University of Colorado Denver College of Engineering and Applied Science may have discovered an answer

  • Fusion power nears

    The long-sought goal of a practical fusion-power reactor has inched closer to reality with new experiments from MIT’s experimental Alcator C-Mod reactor, the highest-performance university-based fusion device in the world; MIT advance helps remove contaminants that slow fusion reactions

  • Declining energy quality root cause of current recession

    A new concept — the Energy Intensity Ratio (EIR) — measures how much profit is obtained by energy consumers relative to energy producers; the higher the EIR, the more economic value consumers (including businesses, governments and people) get from their energy; to get the U.S. economy growing again, Americans will have to increase the U.S. EIR by producing and using energy more efficiently

  • World running out of cheap coal

    Most estimates of coal reserves suggest there is plenty to last at least a couple of hundred years, and a new report does not dispute this; the report says, rather, that using this coal will become progressively more expensive as the world is running out of coal that can be easily and cheaply recovered

  • 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

  • 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

  • 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

  • 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

  • Study to assess use of wave turbines along U.S. coastline

    A Scottish company will deploy its wave-power technology along the Oregon coast for a feasibility study of wave power; the state of Oregon has given the company a grant to measure and record the frequency, intensity and height of waves as they approach the Oregon shoreline

  • Oxford U researchers harness tidal energy

    U.K. waters are estimated to offer 10 percent of the global extractable tidal resource; an Oxford University spin-off has been set up to commercialize a tidal turbine concept developed by Oxford researchers

  • PG&E to improve pipelines safety

    Following the deadly natural gas pipeline explosion in San Bruno, California, on 9 September, PG&E said it would upgrade its California pipeline system to boost safety; a key element will be the installation of hundreds of automatic shutoff valves to replace the current manual valves; the company would also contribute $10 million to a nonprofit group to develop better diagnostic tools to determine the condition of underground pipelines

  • Goal of eliminating HEU reactors faces hurdles

    To lessen the risk of terrorists getting their hands on bomb-grade materials, the U.S. has led an effort to end the use of highly enriched uranium (HEU) in research reactors around the world; 72 HEU reactors have been modified or shuttered, but various government and academic facilities still operate around 130 HEU reactors — and these operators are reluctant to switch because of the complexities involved in changing to a new technology

  • Regulators: N.J. nuclear plant employee was an Islamic jihadist

    A 26-year old American, Sharif Mobley, now under arrest in Yemen for terrorist activities, became an Islamic militant while working for six years at several nuclear plants in New Jersey, Pennsylvania, and Maryland; the man — who told fellow workers “We are brothers in the union, but if a holy war comes, look out” — had unescorted access to the interior of the plants; to have unescorted access to secure areas of a nuclear power plant, a person must undergo a background investigation, including a criminal record check and a psychological assessment — but the rules did not account for temporary workers who migrate from plant to plant, as Mobley did

  • Nuclear power making a come back

    If Germany, where most of the public is suspicious of nuclear power, plans to extend the life of its nuclear reactors, the world must have entered a new atomic age; indeed: around the world, more than 150 reactors with a total net capacity of almost 170,000 megawatts are planned and more than 340 more are proposed, according to the World Nuclear Association
