A University of Calgary research team developed a new method for extracting carbon dioxide (CO₂) directly from the air — a fundamental shift in carbon capture technology enabling capture of the most common greenhouse gas from so-called diffuse sources like aircraft, trucks and automobiles that represent half of the greenhouse gases emitted globally.

Professor David Keith, Director of University of Calgary’s (UofC) Institute for Sustainable Energy, Environment and Economy (ISEEE) and a team of researchers from UofC’s Energy and Environmental Systems Group built and operated a prototype system this summer producing results that compared favourably with commercial carbon capture systems. Two ‘provisional’ patents have been filed on the technology but Keith warns there are still “many pitfalls along the path to commercialization.”

Using a process adapted from the pulp-and-paper industry that halves the cost of CO₂ air capture in their custom-built tower, Professor Keith and his team captured the equivalent of about 20 tonnes per year of CO₂ (approximately equal to the yearly output of one person in North America) directly from the air with less than 100 kilowatt-hours of electricity per tonne of carbon dioxide on a single square metre of scrubbing material.

“This means that if you used electricity from a coal-fired power plant, for every unit of electricity you used to operate the capture machine, you’d be capturing 10 times as much CO₂ as the power plant emitted making that much electricity,” explains Professor Keith.

A report co-authored by Keith in the American Chemical Society’s journal Environmental Science & Technology explains “nearly all current research on carbon capture and storage (CCS) focuses on capturing CO₂ from large, stationary sources such as power plants. Such plans usually entail separating CO₂ from flue gas, compressing it, and transporting it via pipeline to be [stored] underground.”

Using CO₂ air capture technology, “a company could, in principle, contract with an oil sands plant near Fort McMurray to remove CO₂ from the air and could build its air capture plant wherever it’s cheapest — China, for example — and the same amount of CO₂ would be removed,” says Professor Keith in a UofC press release.

“While it’s important to get started doing things we know how to do, like wind power, nuclear power, and ‘regular’ carbon capture and storage,” Professor Keith continues, “it’s also vital to start thinking about radical new ideas and approaches to solving this problem.”

ISEEE’s Executive Director David Layzell points out that “energy-efficient and cost-effective air capture could play a valuable role in complementing other approaches for reducing emissions from the transportation sector, such as biofuels or electric vehicles.”

Ian Narev, the CEO of the Commonwealth Bank of Australia, this morning “unreservedly” apologised to clients who lost money in a scandal involving the bank’s financial planning services arm.

Last week, a Senate enquiry found financial advisers from the Commonwealth Bank had made high-risk investments of clients’ money without the clients’ permission, resulting in hundreds of millions of dollars lost. The Senate enquiry called for a Royal Commission into the bank, and the Australian Securities and Investments Commission (ASIC).

Mr Narev stated the bank’s performance in providing financial advice was “unacceptable”, and the bank was launching a scheme to compensate clients who lost money due to the planners’ actions.

In a statement Mr Narev said, “Poor advice provided by some of our advisers between 2003 and 2012 caused financial loss and distress and I am truly sorry for that. […] There have been changes in management, structure and culture. We have also invested in new systems, implemented new processes, enhanced adviser supervision and improved training.”

An investigation by Fairfax Media instigated the Senate inquiry into the Commonwealth Bank’s financial planning division and ASIC.

Whistleblower Jeff Morris, who reported the misconduct of the bank to ASIC six years ago, said in an article for The Sydney Morning Herald that neither the bank nor ASIC should be in control of the compensation program.

President Pervez Musharraf of Pakistan gave up his uniform in a ceremony yesterday in Rawalpindi. He handed power over to General Ashfaq Parvez Kayani at the headquarters of the Pakistani Army, after being the leader of the army for nine years.

In his final address as leader of the army, he said that the army was the saviour of Pakistan and that the army was his life. He also expressed his pride in being the leader of what he called a “great force.”

Musharraf had been under a lot of pressure to quit as army chief, since the country was put into the spotlight as a result of a state of emergency being declared. He is expected to be sworn in as the civilian president of Pakistan on Thursday.

Both the opposition leader, Benazir Bhutto, and the US secretary of state, Condoleezza Rice, welcomed the change of duties. However, Bhutto indicated her party may not be prepared to accept Musharraf in his new non-military leadership role. Condoleezza Rice requested the state of emergency be lifted before the planned elections, which are due to take place in January.

Musharraf said General Kayani was “an excellent soldier” and that “the armed forces under his command will achieve great heights.”

General Kayani was named as the successor to Musharraf in October, before the state of emergency was declared in early November.

Soprano Beverly Sills, who brought opera to United States popular culture through frequent television appearances, died last night at her home in New York. She was 78.

Born Belle Miriam Silverman on May 25, 1929 in Brooklyn, she was nicknamed “Bubbles”, and started singing at age three, winning talent contests and singing on the radio.

She made her professional stage debut in 1945, with a touring Gilbert and Sullivan show, and in 1947, started singing opera as Frasquite in Carmen with the Philadelphia City Opera. She sang with the San Francisco Opera and the New York City Opera.

She married in 1956 to journalist and Cleveland Plain Dealer publishing heir Peter Greenough, and had two children with him. One was deaf and the other mentally retarded, so Sills curtailed her performances to care for them.

She returned to opera in 1962, with the Opera Company of Boston, and then reached her peak singing years in the mid- and late-1960s, singing with the New York City Opera.

She made her debut with the Metropolitan Opera in April 1975, receiving an 18-minute ovation for her performance in The Siege of Corinth.

At the height of her popularity in the 1970s, she was a regular guest on television variety shows with Danny Kaye, Carol Burnett and The Muppet Show. She was even a guest host on Johnny Carson‘s The Tonight Show. For two years, she had her own weekly talk show. Sills graced magazine covers, such as Time and Newsweek, as an example of an American who conquered the European-dominated world of classical music.

After retiring from performing in 1980, Sills became the general manager of the New York City Opera. She became the chairman of Lincoln Center for the Performing Arts in 1994, and 2002 was appointed head of the Metropolitan Opera.

Sills had surgery for cancer in 1974, but it had been revealed last month that she was ill with an aggressive form of lung cancer, though she never smoked. She died about 9 p.m. ET yesterday at her home in Manhattan with her family and doctor at her side.

Glen Stollery is a New Zealand website developer who created the site ScienTOMogy.info in mid 2005. The site, which is a parody of Tom Cruise and his involvement with the Church of Scientology, became the centre of controversy when it was served with a number of cease and desist orders initiated by the Church. On March 19, 2006, Glen issued a media release stating that his web hosting provider, YouTube, had removed videos of Tom Cruise which formed part of the site. The release suggested that YouTube had taken this action under external pressure from Cruise or Viacom.

Responding to a query by Wikinews reporters, YouTube stated “We have not received a DMCA notification letter from Viacom.” The Church of Scientology was offered the opportunity to respond to the claims made by Stollery during the interview. No reply was received.

This exclusive interview deals with these issues and others relating to the website. It was conducted with Glen via email between March 21 and April 3, 2006.

The US economy added 173,000 jobs in August, the Bureau of Labor Statistics reported on Friday. The unemployment rate fell from 5.3 to 5.1 percent, the lowest since April 2008.

Although August job gains were lower than most economists forecast, job growth numbers for June and July were revised upwards by a combined 44,000. Average job gains over the past three months stand at 221,000, compared to March-May’s 189,000 monthly average. Over the past twelve months, job growth has averaged 247,000 per month.

Average hourly earnings rose 0.3 percent, or 8 cents, marking the largest increase in earnings in seven months. Hourly earnings had risen by 6 cents in July. Wages have risen by 2.2 percent over the past year.

Job growth in August was primarily concentrated in the health care and social assistance, financial activities, and professional and business services sectors. Those three areas of the economy added a combined 108,000 jobs. Food service and drinking places employment increased by 26,000 over the month, and other economic sectors saw employment hold steady. Manufacturing, on the other hand, saw employment decline by 17,000 in August. A stronger dollar and worldwide economic weakness make US exports less desirable, leading to a flattening in manufacturing employment so far this year after steadily rising in the early years of the US economic recovery.

The solid overall job gains led analysts to slightly raise expectations for a decision by the Federal Reserve to raise interest rates this month. Investors raised the likelihood of a September rate increase from 26 percent before the jobs report to 30 percent, and stocks dropped by over one percent on Friday. “The payrolls data is certainly good enough to allow for a Fed rate hike in September,” said Deutsche Bank’s head of currency strategy, Alan Ruskin. “The big question is still whether financial market volatility will scupper the plans.”

“This is the first time the market has looked at a Fed meeting and really has no idea what the Fed is going to do,” said Mark Kepner, a New Jersey equity trader with Themis Trading. “Right now you’re looking at the overall uncertainty and that’s what’s hanging on the market. I don’t think this number in and of itself changes how somebody’s going to vote.”

NASA is beginning the final preparations for next Wednesday’s launch of the Dawn probe, aboard a Delta II rocket. The Dawn probe, costing over US$250 million, will visit the dwarf planet Ceres and the asteroid Vesta. The launch was originally planned for mid-June, however due to a damaged crate, shipping delays, and a damaged solar panel, NASA chose to delay it until now. Last week the spacecraft was delivered to the launch pad, and engineers performed tests to ensure that it is ready for launch. Today, the payload fairings were installed, and the probe is ready for its launch next week onto its 5 billion kilometer (3.2 billion mile) mission.

As the Delta II launches, three stages of rockets will propel the probe towards its first target. With the help of ion thrusters, it will reach Mars in mid-2009. Using Mars’ gravity, the probe will speed up and proceed towards the first asteroid, Vesta, in late 2011. After orbiting for seven months, it will leave Vesta in mid-2012, and arrive at Ceres in 2015. After making scans of Ceres, it will enter an orbit around Ceres that will ensure that it does not impact the asteroid for half a century. This is required due to the United Nations’ “Outer Space Treaty”, which states that “harmful contamination” of these asteroids must be avoided.

The targets of this mission, Ceres and Vesta, couldn’t be less alike. Ceres (diameter 975 km, 600 miles) is larger than Vesta (578 km, 350 miles). This makes Ceres approximately the size of Texas. NASA believes Ceres could contain water beneath its outer crust because, like Earth, its inner layers are heavier than the outer layers, and Ceres’ outer layer is lighter than water. Vesta, on the other hand, is the size of Arizona, and has a surface of volcanic rock, which astronomers believe came from its hot inner layers. Vesta also has a large crater – almost 500 km (300 miles) across – on its southern pole. The collision that caused this likely blasted enough rock into space to fill a container 160 by 160 by 80 km (100 by 100 by 50 miles).

The probe will make several observations of these asteroids: it will compare the makeup, shape, size, and densities, analyze craters, and determine mass, gravity, rotation. To determine the makeup, the probe carries a mapping spectrometer, and tools to map emissions of neutrons and gamma rays. Using this information, NASA can compare the formation of these bodies to learn more about our solar system, for example, to test a theory which states that a number of stony meteorites may be debris from Vesta.

There’s one more piece of equipment aboard the probe: A small silicon chip containing the names of 350,000 people who submitted their names to the “Send Your Name to the Asteroid Belt” campaign. After next week’s launch, the spacecraft will deploy its solar panels and undergo two months of testing before it begins the cruise to Mars.

Ali Akbar Salehi, chief of Iran’s Atomic Energy Agency, announced Friday that Iran is scheduled to launch its first nuclear power plant in Bushehr. Russia said that it will start loading fuel into the reactor on August 21, 2010.

Russia has assisted Iran in the construction of this reactor since the mid-1990s. The proposal to build this reactor was put forth 35 years ago by Mohammad Rez? Sh?h Pahlavi, the former emperor of Iran.

Dmitry Anatolyevich Medvedev, the current president of Russia, said that Iran and Russia are in active trade partnership. Medvedev called on Iran last month to explain its nuclear program.

The official launch is scheduled for August 21, 2010. Russia has promised to run the plant by supplying fuel and taking away fuel waste.
