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.”

Homebush Bay, New South Wales —Wikinews sat down with Great Britain men’s national wheelchair basketball player Joni Pollock before a practice session at the Rollers & Gliders World Challenge in Sydney.

British-born Pollock was born with the condition spina bifida. He explained he could walk with difficulty up until age twelve or thirteen, after which he began using a wheelchair. Shortly after this, he began playing wheelchair basketball. He attended a disabilities tournament for children with disabilities in England, where he tried both wheelchair basketball, since he came from a town where team sports were popular; and wheelchair tennis, as he’d played with an able-bodied friend. Ultimately, he chose wheelchair basketball as it was a team sport.

Wikinews asked Pollock about being loud towards his team mates during the match on July 20 between the Australian Rollers and the Great Britain Bulldogs. He said he was out of wheelchair basketball for nine months due to a pressure sore and surgery on his shoulder, and has been making a comeback since January, with the doctors and physiotherapists giving him the all-clear in April. On that night, he said, the Australian team used bullying tactics and some of his teammates on the British team didn’t step up to win the game. He also said that no matter what team his team plays against, he has a target on his back because of his calibre of playing in the game, and his team failed to to understand it that night, leaving him frustrated with his team and himself; and, he hates coming to Australia during a Paralympic year since the home town —that is, Australian— referees do not protect the visiting team from the home team’s dirty playing, which puts the British team’s gold medal prospects in jeopardy.

Wikinews also asked Pollock his opinions regarding Oscar Pistorius. Pollock believes Pistorius shouldn’t be competing in the Olympics if other Paralympic athletes can’t compete. He also mentioned reservations about certain technical aspects, such as whether Pistorius would be the same height if he still had his legs rather then his prosthetic legs. Asked about 5 point players playing in wheelchair basketball, he said he believes 5 point players can play with other point players but not in the Paralympics, and said 5 point players currently play in the domestic league but not at the elite level, to boost the number of players participating and to help the development of the game.

Wikinews also questioned him about tattoos worn by members of the British team. In previous years, he said, only one or two forwards had tattoos, but now almost everyone has one as having tattoos is currently in fashion. He said he got his first tattoo at the age of sixteen and only recently had it removed. He also has tattoos on his right arm, depicting the logos of the Paralympics and World championships in which he competed.

Pollocks’s team begins its London campaign on August 30, against the Germany men’s national wheelchair basketball team.

The United States’s largest car manufacturer General Motors today named Mary Barra as its new chief executive.

Barra, 51, will be the first woman to lead a firm in the American auto industry. She has been with General Motors for 33 years, and is currently the global head of product development.

She said in a statement: “With an amazing portfolio of cars and trucks and the strongest financial performance in our recent history, this is an exciting time at today’s GM. I’m honored to lead the best team in the business and to keep our momentum at full speed.”

She replaces Daniel Akerson, who was appointed by the government as both chief executive and chairman in 2009 during the company’s bankruptcy. Akerson plans to stand down on January 15 following his wife’s advanced cancer diagnosis.

In a message to employees, he said: “I will leave with great satisfaction in what we have accomplished, great optimism over what is ahead and great pride that we are restoring General Motors as America’s standard bearer in the global auto industry.”

Akerson will also relinquish his chairman role, to be replaced by current director Theodore Solso. The company also announced head of finance Daniel Ammann as its new president.

The appointment comes just days after the US government sold the last of its shares in the company, losing around $9 billion on its initial bailout in 2008 that saw 61% of the firm coming under public ownership.

General Motors recovered from their bankruptcy a year after the appointment of Akerson, and re-entered the stock market in November 2010. It remains the largest car manufacturer in the United States, posting sales figures of $152 billion in 2012. It currently produces fifteen brands of vehicle in 37 countries.

Barra holds a bachelor’s degree in electrical engineering from Kettering University in Flint, Michigan, and was recently listed by Forbes as the 35th most powerful woman in the world.

In an attempt to speak with as many candidates as possible during the 2008 Canadian federal election, Wikinews has talked via email with John Kittredge. John is a candidate in Toronto, Ontario’s St. Paul riding, running under the Libertarian Party banner. Libertarians are a minor, registered political party; they are looking to earn their first ever seat in the House of Commons.

Incumbent Carolyn Bennett of the Liberals is running against Libertarian Kittridge, Conservative Heather Jewell, New Democrat Anita Agrawal, and Justin Erdman, a Green. Bennett was the Minister of Health under previous Prime Minister Paul Martin’s Liberal government. Since it was created in 1935, the riding has been batted about between the Liberals and the now defunct Progessive Conservative party.

The following is an interview with Mr. Kittridge, conducted via email. The interview has had very limited editing, to eliminate in-text mentions of website addresses, but is otherwise left exactly as sent to Wikinews.

The Wikileaks website, which publishes sensitive and censored material submitted by anonymous contributors, has experienced unprecedented levels of Internet traffic today through public interest. This interest has caused the website’s servers to be unable to meet the demand of over 164 gigabytes of download traffic within twenty-four hours, leading the site to be temporarily inaccessible.

The film Fitna, directed and produced by Dutch politician Geert Wilders, has caused controversy for its presentation of Wilders’ negative view of Islam as being committed to world domination and acts of terrorism. A trailer for the film was widely uploaded to many video sharing sites, including YouTube and Google Video; this met with anger from Islamic nations, the debacle culminating in Pakistan’s government ordering the nation’s internet service providers to block the YouTube site. This caused YouTube to be inaccessible to residents of other countries whose Internet service providers’ equipment automatically began routing traffic to YouTube via Pakistan Telecom’s servers, due to their ban accidentally propagating to other providers. Ultimately, YouTube acquiesced to the demands made by Pakistan and other organisations, in exchange for access being restored. The site LiveLeak originally hosted a copy of the trailer, which has now been replaced with a video message stating that the lives of their staff have been put at risk due to hosting it.

As a consequence of this censorship, Wikileaks mirrored the video, receiving heavy access traffic through hosting one of the few copies remaining on the Internet. Wikinews has obtained an exclusive statement from a representative of Wikileaks, affirming that the site has not been taken off-line due to external pressure, and is instead suffering technical problems due to this high demand. The representative gave the following statement:

Wikileaks gained recent public attention in the Bank Julius Baer vs. Wikileaks lawsuit, following publication of leaked documents that were alleged to provide evidence of money laundering, tax evasion and asset hiding by Swiss financial institution Bank Julius Baer. The documents are said to have been uploaded by Rudolf Elmer, a former chief operating officer of the bank’s Cayman Islands division, who was sacked following an investigation by the bank that involved polygraph testing. Wikileaks has not, however, stated that Elmer was the source of the documents. Bank Julius Baer sought an injunction against the operator of Wikileaks’ domain name, Dynadot, to remove access to the site from the Wikileaks.org domain; this was granted by the U.S. District Court for the Northern District of California. The site was consequently inaccessible through this domain, although access could be obtained through many alternate addresses. Following activity by organisations such as the Electronic Frontier Foundation and the American Civil Liberties Union, who sought to defend the right to free speech that Wikileaks relied upon, the lawsuit was dropped and access was restored.

A man named George Schultz in Parksville, British Columbia is selling the boat from old TV series Gilligan’s Island at the cost of $99,000. The cruiser, originally cost about $290,000 in the 1960s.

“There have been a couple of modifications, so it doesn’t look exactly like the original,” said Shultz, a boat broker who’s selling the 36-foot Wheeler Express Cruiser for fellow Parksdale resident Scotty Taylor. “But it’s still the original boat.”

Originally, the boat’s name was The Blue Jacket.

“Just for the show, for a stage name, it was called the S.S. Minnow,” Shultz said. The name was a reference to Newton Minnow, once chairman of the FCC.

“He just liked the boat, he wanted to restore it, it was a nice looking boat, a wooden boat, a classic and he likes classic boats,” said Shultz. “The hole in the hull was actually the least of the repairs – the interior needed a lot more work”.

Someone later stole the plaque on the boat, but the 46-year-old boat still has the round life preserver with S.S. Minnow emblazoned on it and the skipper’s chair.
