• Smart grid runs into trouble over powerline standard, I

    The U.S. government has awarded $4 billion in grants to build a smart electric grid; appliance makers need an easy, low cost way to plug into the grid; today they face as many as a dozen wired and wireless choices, most of them far too expensive and high bandwidth, focused on carrying digital music and video around the home rather than on helping save energy

  • World heading for a uranium crunch

    Nuclear power has become more attractive as a result of fluctuating oil prices and growing concerns about the environment; trouble is, the world is running out of uranium

  • Climate change threatens Canada North's infrastructure

    Climate change is felt more acutely in the arctic, and a Canadian government’s report says that winter roads melting earlier in the spring could force communities to airlift supplies, while increased snowfall and changing ice conditions can add stress to buildings as well as energy and communications infrastructure

  • Boeing, Edison awarded part of $620 million to build smart grid

    The Department of Energy the other day awarded $620 million in funding for building a more efficient and resilient power grid

  • U.S. grid-security measures may hurt Canadian companies

    The growing concern in the United States over the security of the national grid has lead to security measures — and proposed legislation — aiming to make the security of the grid more robust; trouble is, much of the U.S. electricity comes from Canada, and some of the contemplated security measures my disrupt transmission of power from across the border

  • Better method to detect cracks in nuclear plants

    At the moment, cracks in nuclear plant components are detected by using ultrasonic scanners that carry a number of different probes; new device will use a single phased-array probe that will be safer, cheaper, and more accurate than existing systems

  • Dutch build sand dunes to fight rising seas

    More than eighteen million cubic meters of sand are dredged from the bottom of the ocean and brought back to land to form new dunes; the new dunes — each 30 to 60 meters wide, and rising up to 10 meters above sea level — are built along a 20-kilometer stretch of the shore

  • Nuclear leaks at Three Mile Island investigated

    There was another radioactive leak at Three Mile Island, the scene of the U.S. worst nuclear power accident; NRC said on Sunday there was no threat to public health or safety; investigators this weekend were trying to determine the cause of radiological contamination inside the nuclear facility’s containment building

  • Predicting the effect of a nuclear weapon dropped on an urban area

    Current models of nuclear effects use wind direction and wind speed to draw a predicted cone-shape area of fall-out; new research results show that these models are too simple in some ways — for instance, they do not include the complex dynamics of wind movements around buildings, which can concentrate fall-out preferentially in certain areas

  • Judge: Corps' mismanagement doomed homes in New Orleans

    The judge’s 156-page decision could result in the federal government paying $700,000 in damages to three people and a business in those areas — but it also sets the stage for judgments worth billions of dollars against the government for damages suffered by as many as 100,000 other residents, businesses, and local governments in those areas who filed claims with the corps after Katrina

  • What tropical countries can teach the U.K. about flood management

    Climate change has caused a change in the patterns of rainfall in the United Kingdom: rather than a procession of predictable showers, a new type of rain emerged — localized storms, dropping a lot of water in one place over a short period of time; villages and towns were overwhelmed; tropical countries have had a long experience with the type of rainfall

  • Doubts raised on nuclear industry viability

    There are two problems facing the nuclear power industry: civilian and military stockpiles and re-enriched or reprocessed uranium sources contribute 25,000 of the 65,000 tons of uranium used globally each year; the rest is mined directly, but scientists say that nobody knows where the mining industry can find enough uranium to make up the shortfall; also, the cost per kilowatt of capacity generated by nuclear power is $4,000; generating identical capacity from coal costs $3,000, and the cost for natural gas generation is $800; this makes the nuclear option a big financial gamble

  • Buildings made of prefabricated straw prove to be fire-resistant

    Researchers at Bath University test panels made from prefabricated straw-bale and hemp by exposing them to temperatures over 1,000°C; to reach the required building standard, the panels had to withstand the heat for more than thirty minutes, but more than two hours later — four times as long as required — the panels had still not failed

  • Texas running out of water

    Texas’s population of about 24.3 million is expected to hit about 45.5 million by 2060, and the water supply can not come close to keeping pace; if the state were to experience major drought conditions with that many more people, officials estimate almost every Texan would be without sufficient water and there would be more than $90 billion in economic losses

  • DHS unveils critical infrastructure Web site

    Designed to provide stakeholders and the public with easily accessible information about their role in safeguarding critical infrastructure and key resources (CIKR); the new CIKR Resource Center will offer information on Web-based seminars on the tools, trends, issues, and best practices for infrastructure protection and resilience; resources concerning potential vulnerabilities for chemical facilities; and guidance for all response partners on how best to prepare for and provide a unified response to disasters and emergencies
