• China's nuclear reactors to use technology rejected by U.S., U.K. as unsafe

    Ten of China’s proposed nuclear power reactors will use Westinghouse’s AP1000 advanced technology; the United States rejected the AP100 design, saying key components of the reactormight not withstand events like earthquakes and tornadoes; the United Kingdom indicated it, too, would reject Westinghouse’s new reactor because it could be vulnerable to terrorist attacks

  • Australia could face climate refugees

    Australia could face a wave of climate refugees from neighboring Pacific islands unless rich nations help poorer countries with climate change, scientists warned; the 900 climate scientists gathered at a the conference heard specialists say that Australia is already experiencing the effects of climate change and is likely to be one of the most severely affected among developed countries

  • U.S. Navy blimp to help track oil flow in gulf

    A U.S. Navy blimp arrived in the Gulf of Mexico yesterday to help detect oil, direct skimmers, and search for threatened wildlife; the blimp can carry as many as ten crew members as it flies slowly over the region to track the direction of the oil flow and how it is washing ashore

  • New long-term threat from oil spill recognized: increasing ocean's arsenic levels

    Oil spills can increase levels of toxic arsenic in the ocean, creating an additional long-term threat to the marine ecosystem; sediments on the sea floor filter naturally occurring arsenic out of seawater, keeping the levels of arsenic low; oil spills clog up sediments on the ocean floor with oil, which prevents the sediments from bonding with arsenic and burying it safely underground with subsequent layers of sediment

  • Can microbes break down oil washed onto Gulf beaches?

    Nature provides its own methods for keeping sandy beaches clean: microbial communities which are native to the sands; researchers are studying whether native oil-eating bacteria that wash ashore with the crude are helping or hindering these native microbial communities

  • U.S. gives $2 billion to solar energy companies

    The Obama administration awarded nearly $2 billion to two solar energy companies for three large solar energy projects — in Arizona, Indiana, and Colorado; the projects will create more than 3,000 jobs, power 70,000 homes, and produce millions of solar panels each year

  • X Prize Foundation may offer $3 to $10 million award for Gulf Oil Spill solutions

    X Prize Foundation, known for offering prizes to innovative and future-oriented innovations, is considering offering a prize of between $3 and $10 million for a viable solution to stopping the oil spill in the Gulf; the foundation in the process of developing a multi-million dollar competition to help alleviate the effects of the oil spill in the Gulf; the X Prize Foundation is best known for what was originally called the Ansari X Prize — a $10 million competition open to anyone who could build a reusable, privately built craft capable of reaching outer space

  • UGI proposes innovative clean-up plan for Gulf

    BP’s oils spill now covers an area the size of Luxembourg; a U.K. clean-tech company joins with an Ohio-based partner to offer boat towing technology platforms specifically designed to remove the oil threatening the beaches of the Gulf of Mexico and the waters around the Deepwater Horizon well; a towed membrane acts like blotting paper in attracting oil that can then be released only by mechanical pressure

  • Bacteria will help keep CO2 safely sequestered

    With the world still heavily reliant on fossil fuels to meet its energy needs, carbon sequestration technologies could help reduce greenhouse gas emissions; one of the big challenges to making this a reality is ensuring that the CO2 stays locked away underground; the humble Bacillus subtilis bacteria will help

  • BP's first relief well has now reached 4,200 meters, with 1,300 meters to go

    BP has been drilling two relief wells in the Gulf of Mexico in an effort to stem the flow of oil from the stricken Deepwater Horizon; a relief well aims to bisect the original well casing, enabling engineers to pump in mud and concrete to seal up the well; drilling into an 18-centimeter-wide cylinder 5,500 meters below the sea floor is not easy

  • Balls of steel: A scientists proposes dropping steel balls into well to stop leak

    Willard Wattenburg made a name for himself by directing the capping of the more than 500 hundred burning oil wells in Kuwait after the Gulf War in 1991; he now proposes dropping steel balls of different sizes into the gushing well; if the steel balls are big enough in diameter, their weight will pull them downward even through the upward-rushing torrent of oil and gas; they will settle into the well at some deep level and begin to clog it

  • Coast Guard solicits private sector ideas on how to stem spill, deal with consequences

    “We’re adapting to an enemy that changes,” Coast Guard Adm. Thad Allen, the national incident commander for the oil spill, said; accordingly, in somewhat of an about-face, the Coast Guard last Friday began to solicit ideas from vendors, scientists, government laboratories, and nonprofits on how to stop, contain, and clean up the largest off-shore oil spill in U.S. history

  • 40,000-plus barrels per day pouring into Gulf

    Since the 20 April explosion of the Deepwater Horizon well, BP has insisted that the amount of oil being spilled into the gulf was no more than 5,000 barrels a day; U.S. government scientists yesterday corrected the company’s assertions, saying that amount is at least 40,000 barrels, if not more; the 1989 Exxon Valdez spilled 10.8 million gallons of oil into Alaska’s Prince William Sound; there are 42 gallons in a barrel of oil, so 40,000 barrels mean 1,680,000 gallons; this means that since 20 April, the BP well has released oil into the Gulf at a rate of one Exxon Valdez every 6.5 days; in other words, between 20 April and 3 June, when the well’s riser was cut, a quantity of oil equal to seven Exxon Valdez has been spilled into the Gulf

  • BP's cost-cutting approach made well vulnerable, left company unprepared

    Safety upgrades are critical but could mean higher prices for oil and gas; to cut costs, BP decided to install a continuous set of threaded casing pipes from the wellhead down to the bottom of its well; this leaves one blind to leaks that sneak up around the casing pipe, and the long string gives gas more time to percolate into the well; a preferred — and costlier — alternative in high-pressure deepwater is a “liner” design in which drillers install and then cement in place a short string of casing in the lower reaches of the well before casing the rest of the well

  • DOE puts raw oil spill data on new Web page

    A new Department of Energy Web page provides numbers on how much oil is being recovered, and schematics of the technology involved in trying the cap the well and the Gulf clean-up
