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.”

In an attempt to speak with as many candidates as possible during the 2008 Canadian federal election, Wikinews has talked via email with David Sparrow. Sparrow is a candidate in Ontario’s Don Valley West riding, running under the New Democratic Party (NDP) banner. The riding was set to vote in a by-election on September 22, 2008, following the resignation of John Godfrey, but Stephen Harper’s sudden election call nulled that effort.

Also running in the Toronto riding are Liberal Rob Oliphant, Conservative John Carmichael, Green Georgina Wilcock, and Communist Catherine Holliday.

The following is an interview with Sparrow, conducted via email. The interview is published unedited, as sent to Wikinews.

Following the Pilkhana massacre which occurred February 25 and 26 leaving 74 dead and the inferno at the Bashundhara City shopping mall complex March 13 leaving seven dead, Prime Minister Sheikh Hasina said security measures are being tightened countrywide across Bangladesh.

Fire drills will be enacted at all key-point installations (KPI). Fire fighting systems will be examined by the fire brigade and the public works department (PWD) to ensure functionality. Security measures will be enhanced supplementing areas under private security such as at the Bashundhara City Complex.

The Fire Service and Civil Defence Department requires modernization and needs new equipment to fight fires past the sixth floor of buildings. The Fire Brigade says it needs turntable ladders, snorkels, foam-tenders, lighting units, emergency tenders, fireproof uniforms, and rescue ropes for fire fighting and rescue operations. Transportation to fires is also an issue due to narrow roads, low electrical wires and congestion.

The Bangladesh National Building Code requires fire fighting equipment installed in buildings over seven floors. This code is to be monitored by authorities to ensure compliance with the new guidelines and to make sure buildings are being maintained.

The Bashundhara City Complex opened Monday for shoppers two days after Friday’s blaze. A probe is underway to determine the cause of the fire and to assess structural damage.

Loss of life was minimized as the blaze broke out on a Friday, the beginning of the weekend in Bangladesh, so offices in the upper floors were empty. The lower eight floors are used for shopping and the upper floors are all Bashundhara Group offices.

The mall is valued at Tk 7.0 billion (US$100 million). It is not known if the complex is covered by fire insurance.

It is estimated that it will take over two years to rebuild the area damaged by flames which were burned down to a skeleton. Bashundhara City’s technical advisor, Latifur Rahman, estimated damages at Tk 2.0 billion (US$29m).

Only one television cameraman has been allowed in to film the burnt area. None of the 2,500 shops, cinemas or cafes were burnt by the inferno. The seventh and eighth floors still experience smoke damage, and there was water damage to merchandise.

A three member committee is currently investigating the cause of the fire which will consist of Iqbal Khan Chowdhury, joint secretary of the ministry, representatives of the police, IGP Noor Muhammad, and fire brigade, Director General Abu Nayeem Md Shahidullah. The committee is required to report within the week with their findings. The forensics department is also sifting through the burnt remains.

The Dhaka Chamber of Commerce and Industries has also formed a committee which has begun interviewing witnesses and recording their testimony alongside the government committee.

It has been discovered that 150 closed circuit cameras were not being used when the fire started. Another mystery is why the mall fire fighting system has been found unused.

“In the shopping mall there is an ultra-technology elevator which runs even without electricity but we have found that locked,” Iqbal Khan Chowdhury, joint secretary (Police) of the home ministry, said. “Why the fire burnt so fiercely is a matter to think. We have to see if there was any incendiary substance there. These matters seem to be mysterious.”

Mall management has been asked to submit substances and items which would have been in the upper floors when the fire started. The fire erupted on the 17th floor and spread quickly to the two floors above and engulfed the three floors below. The aerial ladders belonging to the Fire Service and Civil Defence reached as high as the 13th floor of the 21-storey building.

Videos have been sent to the United States (US) for examination to assist in determining the cause of the fire and to help in the damage assessment. Experts from the US are expected to arrive soon.

Firefighters were brought to the rooftop of the 20-storey tower by helicopter. The only fatality in this operation was Baki Billa, a firefighter of Bashundhara City firefighting department, who fell when climbing down a rope from a helicopter to the roof of the building. Three other firefighters made the transition safely. At this same time, the chief security officer was safely rescued by the Bangladesh Air Force helicopter, a Bell 212. Six security officers of the complex also lost their lives.

A memorial service was held Thursday for Adrienne Nicole Martin, the model found dead two weeks ago in the Missouri, US mansion of former Anheuser-Busch CEO August Busch IV. Martin, of Native American ethnicity, was 27 years old when she died of unknown causes, said investigators.

Martin, who had been dating the 46-year-old Busch for “the last several months” according to friends, was a native of Springfield. She had previously been married to 45-year-old doctor Kevin J. Martin until February 2009, when they divorced, and had joint custody of their eight-year-old son. Adrienne Martin had a profile on iStudio, a modeling website, where she said she wanted to become an art therapist. She also expressed a desire to “to do beer advertising” and work in the modeling industry. At the time of her death, Martin had been working toward a master’s degree in art therapy.

The memorial service for Martin was held at South Haven Baptist Church in Springfield. Busch was not among the estimated 100 people attending the service, nor was he mentioned during it. The only speaker was the church’s pastor, Scott Watson, who read letters from Martin’s friends. Her son and other relatives sat in the front row while she was remembered as a gifted artist and dedicated mother. Lacy Elet, one of Martin’s friends, later said Martin was happy that “her life was finally in order.” Her obituary in the Springfield News-Leader called Busch “the love of her life.” However, one of Martin’s uncles, Andy Eby, said after the service, “There are too many questions and not enough answers.”

Martin was found unconscious by Michael Jung, who worked at Busch’s mansion, at 12:30 p.m. local time (18:30 UTC) on December 19. At 1:12 p.m., Jung called emergency services, saying, “This girl’s just not waking up.” When asked if she was breathing, Jung responded with, “We don’t know. It’s dark back there. I’m gonna get a light and try and see.” At 1:26 p.m., Martin was pronounced dead at the scene by emergency workers. Law enforcement officials said the room was dark because there were blackout “curtains drawn in the bedroom.”

An autopsy on Martin’s body did not find any trauma-related injuries, and the official cause of death has not been established by investigators. A toxicology report, expected to take several weeks, will likely be used to determine the reason Martin died. Police said Martin’s body did not exhibit any “apparent signs of trauma or other indications of cause of death.” According to her ex-husband, Adrienne Martin had a rare heart condition, called Long QT syndrome, which can cause palpitations and sudden cardiac death. Kevin Martin said his ex-wife never sought medical advice on her condition and did not talk about it with friends.

Police said that Busch was home at the US$2 million mansion when Martin was discovered, and that the ongoing investigation is being handled by the Frontenac Police Department and the St. Louis County Medical Examiner’s Office. Art Margulis, a lawyer for August Busch IV, said Martin was visiting the Huntleigh residence and that there is “absolutely nothing suspicious” surrounding her death.

On August 21, the Polish weekly Przekrój published an advertisement for Dan-Mark exercise books, bearing the logo of 4fun.tv, a Polish music/interactive TV station. Part of the advertisement contained a definition of the word “exercise book”. The wording looked familiar, and Wikinews consulted Wikipedia, the collaborative online encyclopedia.

Upon seeing the Wikipedia definition, it appeared that the entry quoted in the promotional material was identical to the initial two paragraphs of the relevant Wikipedia entry.

Freelance reporters for the Polish Wikinews decided to find out the reason for such a similarity and whether either of the texts (the advertisement’s or Wikipedia’s) might be a case of copyright violation.

The reporters contacted a Jaros?aw Janas, Creative Director of 4fun.tv., where the ad appeared. His reply included the following claim:

Copyright on text does not last for fifty years as claimed by Janas, but for 70 years after the death of the author.

To investigate the authenticity of the above claims, Wikinews asked the main author of the two paragraphs in question, Wikipedian Julo, about the sources used to write the entry. He confirmed that he had written the text in question, and not copied it from an encyclopedic publication as claimed by Jana.

It is therefore impossible that both Julo and the people responsible for the exercise book advertisement have used the same uncopyrighted encyclopedia, thus coincidentally creating identical texts. The reporters also noted that the first draft of the introduction to the article was written by WaldemarWolskiHuta (February 2006). Afterward the text had undergone some modifications by Julo (September 2006), as well as Picus viridis and Beno (March 2008). However, the text presented in the press promotional material, which – according to 4fun.tv – came from an old-print encyclopedia is identical to the Wikipedia entry after the changes mentioned above had been made. Julo added that he was still alive, together with the other authors of the article in question who constituted the group of the copyright co-holders. This naturally led to a conclusion that neither 50 nor 70 years could have passed since their death. He left 4fun.tv’s actions with a comment that although the contents he and the other Wikimedians had made public and free, they are far from making them available in any “free style”, but under a specified license.

In follow up messages to Jaros?aw Janas, Wikinews reporters confronted the creative director over his seemingly inaccurate claims.

Wikinews was told in a reply that 4fun.tv would ignore the claims unless they see permission from the author of the original content to investigate this story. They were also informed that further e-mails without any specifics sent by the reporter would be qualified as spam. 4fun.tv’s creative director further added that he found the reporter’s picture on the Internet and asked how the person would feel if this picture was to appear on billboards or press releases that advertised the TV station.

Wikipedia does allow copying of its content under certain conditions. The encyclopedia’s content is released under the GNU Free Documentation License, which means that it can be copied, modified, and used commercially and non-commercially – under the conditions that the license’s text is included with the copied content and the five main authors are mentioned. If a part of the article is used, like in the example quoted in this news story, a “right to quote”, recognized by Polish law, may be used. In such a case it suffices to mention the source of the text (Polish Wikipedia) and the author of the excerpt. 4fun.tv met none of these conditions, meaning that copyright has been violated.

Over a year ago Polish Wikinews reported on a similar problem, regarding the use of free-licensed photographs. Since that time such “borrowings” have become less frequent, however photos are still being used in discordance with the license. Journalists have gotten used to citing sources, e.g. Wikipedia, although licensing conditions require attributing the actual author, not the source. So instead of attributing John Doe for his contribution, agencies like Polska Agencja Prasowa (Polish Press Agency) are attributing the source, Wikipedia.

In early September 2008 a similar situation occurred in relation to the Polish edition of Wiktionary. Gazeta Wyborcza, a Polish daily, published an IKEA advertisement, on the opening page of which an almost word-for-word Wiktionary entry was placed; additionally the advertisement used the characteristic MediaWiki layout. The reference to the external source used was missing.

In April 2008, an example of an Australian professor was cited; the scientist, in a reply to a news story, quoted a Wikipedia definition almost word-for-word. The same professor condemned the use of Wikipedia in his previous press appearances.

In 2005 Wikipedia material was discovered in the German weekly magazine Der Spiegel, which acknowledged its fault and published appropriate apologies in place of the article in the online edition.

Frontline magazine in 2007 was found using an image from Wikipedia without proper credit. When pointed out the magazine acknowledged the failing and a correction was promptly given in the subsequent issue.

The handling of the devastation left by Hurricane Katrina, considered by many to be inadequate, has prompted scathing criticism of American politicians. President Bush was criticized for verbally “pandering” to public opinion, while little is done about the tragedy. In a WWL radio interview, New Orleans Mayor Ray Nagin called for a “moratorium on press conferences” and said, “[The government is] feeding the public a line of bull, and they are spinning, and people are dying.” The mayor has since apologised for these remarks. However, the mayor did not address his own alleged failure to evacuate his citizens when he reportedly left hundreds of city-controlled buses idle.

Malik Rahim, a recent Green Party candidate for New Orleans City Council, describes the poor organization as criminal, and called for his party to come help when the federal government would permit it. Grammy award-winning rapper Kanye West created controversy when he said “George Bush doesn’t care about black people” and that “America is set up to help the poor, the black people, the less well-off as slow as possible” in a telethon for victims of Hurricane Katrina.

Onsite television news reporters have also levied very harsh criticism against the politicians whom they were interviewing. Anderson Cooper (CNN) took Sen. Mary Landrieu (D., Louisiana) to task for her detachment (WMV, trancsript). Andrea Mitchell (MSNBC), Bill O’Reilly (FOX), Geraldo Rivera (FOX), Scarborough (MSNBC), Shepard Smith (FOX), Robert Siegel (NPR), and Paula Zahn (CNN) have also harshly criticized their interviewees (WMV). One broadcaster bitterly exclaimed “The only difference between the chaos of New Orleans and a Third World disaster operation, was that a foreign dictator would have responded better.”

In a press release issued September 3rd, 2005, Democratic Senator Mary L. Landrieu of Louisiana claims that President Bush staged a photo opportunity by having rescue equipment quickly moved into the background during the event. Senator Landrieu claims the equipment was dispersed elsewhere the next day. Landrieu says in her press release, ” … we witnessed a hastily prepared stage set for a Presidential photo opportunity; and the desperately needed resources we saw were this morning reduced to a single, lonely piece of equipment. The good and decent people of southeast Louisiana and the Gulf Coast — black and white, rich and poor, young and old — deserve far better from their national government …” The breached levee was closed on Monday by a sequence of dump trucks building a narrow pathway across the gap toward helicopter-dropped sandbags.

Some responses, however, have concerned themselves not with criticizing the response, but praising the hurricane itself. The American Family Association’s Agape Press published praise for the hurricane’s destruction as an instrument of God’s mercy, in that it “wiped out rampant sin”. Rev. Bill Shanks, pastor of New Covenant Fellowship of New Orleans, said “God simply, I believe, in His mercy purged all of that stuff out of there — and now we’re going to start over again.” “New Orleans now is abortion free. New Orleans now is Mardi Gras free. New Orleans now is free of Southern Decadence and the sodomites, the witchcraft workers, false religion — it’s free of all of those things now,” Shanks says.
