• Study: U.S. grid robust, hard to bring down

    Reliance on a particular kind of mathematical model — a so-called topological model — for understanding complex systems has led a growing number of researchers to conclude that the U.S. electric grid is exceedingly vulnerable to disruption; two mathematicians now argue that these studies “have ignored the physics of how things actually work — like electricity infrastructure”; an examination of how the grid actually works would show that the U.S. electrical grid is probably more secure that many people realize

  • U.S. power grid easy prey for hackers

    Attackers could manipulate power-grid data by breaking into substations and intercepting communications between substations, grid operators, and electricity suppliers; grid hackers could make millions of dollars at the expense of electricity consumers by influencing electricity markets; they could also make the grid unstable, causing blackouts

  • Large parts of the world are drying up

    The soils in large areas of the Southern Hemisphere, including major portions of Australia, Africa, and South America, have been drying up in the past decade as a result of intensified “evapotranspiration” — the movement of water from the land to the atmosphere

  • Experts: Stuxnet "a game changer"

    EU cybersecurity agency warns that the Stuxnet malware is a game changer for critical information infrastructure protection; PLC controllers of SCADA systems infected with the worm might be programmed to establish destructive over/under pressure conditions by running pumps at different frequencies; Dr. Udo Helmbrecht, chief of EU’s cybersecurity agency: “Stuxnet is a new class and dimension of malware—- The fact that perpetrators activated such an attack tool, can be considered as the ‘first strike’ against major industrial resources. This has tremendous effect on how to protect national [cyber and critical infrastructure] in the future’

  • Securing privately owned critical infrastructure networks

    Securing the industrial control systems (ICS) and supervisory control and data acquisition (SCADA) networks that are used to run the U.S. critical infrastructure is a daunting job; as in other areas of critical infrastructure protection, ICS and SCADA risk mitigation falls to private owner-operators, as do the costs

  • 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

  • Iran: Stuxnet part of Western sabotage campaign

    Iran claims that the Stuxnet virus which infected more than 30,000 computers used in industrial control systems in the country — many of them in Iran’s nuclear weapons facilities, especially to yet-to-become operational Bushehr nuclear power plant — is part of a covert Western plot to derail its nuclear program; this is the most direct admission by Iran that the West — read: the United States and Israel — have been engaged in a systematic covert sabotage campaign to derail Iran’s weapons program

  • Israel unveils UAV combining aircraft, helicopter capabilities

    The UAV combines the capabilities of an aircraft with helicopter-like hovering, a tilt-rotor propeller, and a fixed-wing vertical takeoff and landing (VTOL) system, which enables a runway-free takeoff and landing on an unprepared area

  • 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

  • Growing concerns about U.S. aging gas pipeline network

    A disturbing realization has emerged from the wreckage of a deadly pipeline explosion in California: There are thousands of pipes just like it across the United States; experts say that pipes of some age were put in the ground before the dense population arrived and now the dense population is right over the pipes; thousands of pipelines across the United States fit the bill, and serious incidents are not infrequent; federal officials have recorded 2,840 significant gas pipeline accidents since 1990, more than a third causing deaths and significant injuries

  • Gas pipeline info kept secret for security reasons, hampering disaster response

    The United States has a 2.5-million-mile network of gas transmission lines; citing fears that terrorists might try to blow up the U.S. natural gas pipelines, federal regulators and the industry have made it extremely difficult for homeowners to learn the location of pipelines and any history of inspections and repairs — information that safety advocates say could save lives

  • San Bruno gas pipe failure started with bad welds or corrosion

    The failure of a natural-gas pipeline that ruptured three weeks ago, devastating a San Bruno neighborhood, may have started along a weld or in a weakened section of the 54-year-old pipe; “This pipe basically unpeeled and failed catastrophically,” said Tom Bowman, chairman of the thermosciences division in Stanford University’s mechanical engineering department

  • Smart Grid Information Clearinghouse Web Portal launched

    Virginia Tech has released the latest version of the Smart Grid Information Clearinghouse (SGIC) Web portal; the portal is the platform for direct sharing and dissemination of relevant smart grid information, ranging from background documents, deployment experiences, technologies, and standards, to on-going smart grid projects around the world

  • India's ambitious thorium-based nuclear energy plans

    With 40 percent of its population not yet connected to the electricity grid and an economy growing by about 8 percent each year, India’s ambitious 3-stage energy security plan includes exploiting the country’s vast reserves of thorium; India could thus find itself a leading global exporter of an alternative nuclear technology that is more efficient than today’s uranium-plutonium fuel cycle
