  • Micro-windmills to recharge cell phones, used for home energy generation

    Researchers have designed a micro-windmill that generates wind energy and may become an innovative solution to cell phone batteries constantly in need of recharging, and home energy generation where large windmills are not preferred. The device is about 1.8 mm at its widest point. A single grain of rice could hold about ten of these tiny windmills. Hundreds of the windmills could be embedded in a sleeve for a cell phone.

  • Promising geothermal resources found on Akutan Island, Alaska

    Akutan Island, in Alaska’s east-central Aleutian Islands, hosts the City of Akutan and is home to the largest seafood production facility in North America. It also hosts Akutan Volcano, one of the most active volcanoes in the United States. During July 2012 the geochemistry of the hot springs on Akutan Island was studied in detail for the first time since the early 1980s. The results from this study document higher concentrations of hydrothermal components in the hot spring waters and an increase in water discharge from the hot spring system. The current heat output of the hot spring system is estimated at twenty-nine megawatts — nearly ten times higher than measured in the early 1980s. This large increase may reflect the volcanic and seismic events of the 1990s, and if so, it cannot be considered a short-term anomaly. Modern geothermal plants could use this heat to generate several MW of electricity. One MW of electric power would supply the needs of about 750 homes.

  • Torrential rain, hurricane-force winds, floods continue to batter U.K.

    Torrential rains, floods, and winds with speeds reaching 108 mph continue to batter south and west U.K., causing massive disruptions to power supply and road and rail transportation. Britain is enjoying a short respite today (Thursday), but meteorologists warned people to brace themselves for more chaos as another storm brings heavy rain, strong winds, and more risk of flooding on Friday and into the weekend. Severe flood warnings, indicating danger to life, remain in place in Berkshire, Surrey, and Somerset, where hundreds of homes have been evacuated.

  • Old-fashioned way to protect high-voltage substations

    There are about 45,000 substations in the United States, but far fewer high-voltage substations like the one attacked last April in Metcalf. California. Americans could see what the loss of just one important power substation can have when, in 2003, a failure in one such substation knocked out power to fifty million people in the United States and Canada for days. Illinois-based IDT says that since Biblical times, the method of thick-walled fortifications to halt manned and artillery attacks remains the best technology for protecting lives and important assets. The company says that its METALITH, a several-feet-thick prefabricated steel barrier structure filled with sand, would offer the best protection to vulnerable power substations. “While most of the electrical industry has been focused on the threat of cyber-terrorism, the San Jose [Metcalf is near San Jose] attack points to the need for physical protection of strategic power grid assets as well,” says Tom Carlton, IDT’s CEO.

  • W.Va. spill leads lawmakers, industry to look at reforming toxic substances law

    The government was slow to respond to the 9 January 2014 massive chemical spill in West Virginia because the law governing such response, the 1976 Toxic Substances Control Act (TSCA), limits regulatory agencies’ authority to investigate such spills.Under TSCA, the EPA must first prove that a chemical poses an unreasonable risk to health or the environment before it can require the needed testing that would show a potential risk. One observer called this a Catch-22, telling a congressional panel that “This is like requiring a doctor to prove that a patient has cancer before being able to order a biopsy.”

  • U.S. takes action against tank car loaders for mislabeling hazardous cargo

    One of the charges against Montreal Maine & Atlantic Railway (MMAR), the rail carrier operating the train which exploded in the small city of Lac- Mégantic, Quebec in July 2013, was that it mislabeled the cargo, claiming it to be less hazardous than it was. The mislabeling and downgrading of the contents of the cars allowed to company to take less rigorous security measures to secure the cars without appearing to break the law. The U.S. Department of Transportation (DOT) is moving against other carriers who mislabel the contents of their cargo to avoid the cost of required security measures.

  • Tracking spilled oil

    A newly developed computer model holds the promise of helping scientists track and predict where oil will go after a spill, sometimes years later. Scientists developed the model as a way of tracking the movement of sand and oil found along the Gulf of Mexico since the Deepwater Horizon oil spill. The new tool can help guide clean-up efforts, and be used to aid the response to future oil spills.

  • The “Mask": Kaspersky Lab discovers advanced global cyber-espionage operation

    Kaspersky Lab’s security researchers have announced the discovery of the Mask (aka Careto), an advanced Spanish-language speaking threat actor that has been involved in global cyber-espionage operations since at least 2007. What makes the Mask special is the complexity of the toolset used by the attackers. This includes a sophisticated malware, a rootkit, a bootkit, Mac OS X and Linux versions, and possibly versions for Android and iOS (iPad/iPhone). The primary targets are government institutions, diplomatic offices and embassies, energy, oil, and gas companies, research organizations and activists. Victims of this targeted attack have been found in thirty-one countries around the world.

  • Natural gas leaks a significant source of green-house gas methane

    Methane, a key greenhouse gas, has more than doubled in volume in Earth’s atmosphere since 1750. Its increase is believed to be a leading contributor to climate change. Where is the methane coming from, however? Research by atmospheric chemist Paul Wennberg of the California Institute of Technology (Caltech) suggests that losses of natural gas – regarded as the “cleanest” fossil fuel — into the atmosphere may be a larger source than previously recognized.

  • U.K. facing flood crisis, as prime minister warns victims they are in for “long haul”

    David Cameron warns flooding victims that they are in for a “long haul,” as the weather service says the weather will get worse this week, leaving thousands more homes at risk. There is a growing anger at the government by residents who complain that in addition to lack of preparation and response – thus, there were many complaints that sandbags intended for the worst-hit areas being “hijacked” and unavailable to stem the rising water – government agencies have not provided enough security after resident were ordered to evacuate, leading to looting of vacant homes. Officials have predicted that thousands more homes will be flooded over the coming days and said restoring the country’s battered rail network could take months.

  • Former FERC chair calls for mandatory security standards for high-voltage substations

    Jon Wellinghoff, the former chairman of the Federal Energy Regulatory Commission(FERC), is leading a crusade to improve physical security around the nation’s electrical grid. Following a 16 April 2013 sniper attack on a San Jose, California substation he is urging Congress to give federal agencies the authority to demand improved security around electrical substations. “This isn’t about this substation or this organized attack,” Wellinghoff said of the California incident. “This is more about the larger issue of physical security of these high-voltage substations nationwide and the need to ensure that some defensive measures start to be put in place.”

  • Israeli legal expert urges development of ethics code for cyberwarfare

    Col. Sharon Afek, former deputy military advocate general, says that countries would benefit from developing an ethics code to govern cyber warfare operations. He notes that existing law already prohibits cyber operations which would directly lead to loss of life, injury, or property damage, such as causing a train to derail or undermining a dam. “Israel faces a complex and challenging period in which we can expect both a cyber arms race with the participation of state and non-state entities, and a massive battle between East and West over the character of the future legal regime,” he writes. He acknowledges, though, that only a catastrophic event like “Pearl Harbor or Twin Towers attack in cyberspace” would accelerate developments in this area.

  • Security of dirty bomb materials in U.S. inadequate: experts

    There are more than 5,000 medical and research devices in the United States containing high-activity radiation sources, including 700 with category-1 sources. Category-1 radiation material could be used by terrorists in dirty bombs. The security measures developed by the industry were written with accident prevention in mind, not in order to thwart a deliberate, forcible effort by terrorists or criminals to gain control of the toxic material. In addition, radioactive materials were considered to be “self-protecting,” because it was assumed that the powerful radiation would deter anyone thinking of tampering with these devices. Terrorist bomb-makers, however, showed themselves to be more technologically-savvy than earlier thought, and, in any event, suicide bombers would not be deterred by the risk of radiation poisoning.

  • Lawmakers want mandatory security standards for national grid

    Lawmakers have urged the imposition of federal security standards on grid operator in order to protect the U.S. national electric grid from attack. The new push follows stories, first reported in the Wall Street Journal reported last Wednesday, about a 16 April 2013sniper attack which disabled seventeen transformer in a San Jose, California substation for twenty-seven days, causing about $16 million in damage. Federal cybersecurity standards for protecting the grid are in place and mandated, but rules for protecting physical sites such as transformers and substations are voluntary.

  • Children living near overhead power lines do not have greater risk of leukemia

    Children who live near overhead power lines in early life do not have a greater risk of developing childhood leukemia, researchers find. The study included nearly 16,500 children who were diagnosed with leukemia in Britain between 1962 and 2008. An earlier study using information on childhood leukemia diagnosed between 1962 and 1995 had suggested that there was an elevated risk for children born within 600 meters of overhead power lines. This new study includes children diagnosed up until 2008, and finds that children born after the 1980s do not have an increased risk.
