Londoners mourn as teletext goes dark, a victim of the DTV transition
Despite the many advantages of digital broadcast television, the transition is separating Europeans from a reliable source of information known as teletext. Citizens of London are the latest to experience the loss, as analog signals in the region were switched off just yesterday. Ceefax, a service of the BBC, has provided millions of Britons with news, sports, weather, television listings, subtitles and games for the past 38 years, and is now accessible only in Kent, Sussex, north-east England and Northern Ireland. Soon, it may cease to exist altogether.
Seen as a precursor to the internet, teletext is a free service that's heavily rooted in analog PAL signals, where small packets of data are sent in the vertical blanking interval, which is otherwise unnoticed by viewers. Because the information is broadcast, users were never subject to network congestion, and only needed to wait a brief moment for their desired page to be transmitted -- more advanced televisions even cached this information locally. As part of the airwaves, the service is naturally free, and in that sense, it lacks a suitable replacement. As with all progress, however, there are casualties, and teletext was an unfortunate bystander. Those who cherished the service can take a moment to relive the memories in the links below.

MINNEAPOLIS / ST. PAUL (04/16/2012) A University of Minnesota invention could help make storage of solar and wind energy more efficient and economical. The invention was licensed to SustainX, a leading global developer of grid-scale energy storage solutions that use patented isothermal compressed air methods to store large amounts of energy cleanly and economically.
"A lot of renewable energy sources, like wind and solar, are unpredictable. The wind doesn't always blow, and the sun doesn't always shine. With economical bulk energy storage, one can really stabilize these energy sources, which makes them more predictable and more reliable," said Perry Li, inventor and mechanical engineering professor in the College of Science and Engineering.
SustainX is developing isothermal (or near-constant temperature) compressed air energy storage (CAES) systems that provide bulk energy storage capacity while reducing carbon emissions and increasing the reliability of the electric grid. The conventional method of compressed air energy storage depends on the use of underground caverns, which greatly limits their available locations and practical use. The SustainX solution uses pipe-type air storage, which makes it possible to store energy virtually anywhere.
"This licensing agreement with the University of Minnesota expands SustainX's growing IP portfolio and provides our company with another possible method of implementing our unique isothermal CAES technology," said Dax Kepshire, SustainX vice president and general manager.
The SustainX energy storage solution could also reduce the need for gas-powered peaker plants that operate during hours of peak energy usage.

Military board: Tea Party Marine should be dismissed
Courtesy Gary Stein / AP, file
U.S. Marine Gary Stein, who has been criticizing Barack Obama on his Facebook page, says he has the right to his opinion like every American.
By Associated Press
CAMP PENDLETON, Calif. -- A Marine who criticized President Barack Obama on his Facebook page has committed misconduct and should be dismissed, a military board recommended late Thursday.
The Marine Corps administrative board made the decision after a daylong hearing at Camp Pendleton for Sgt. Gary Stein.
The board also recommended that Stein be given an other-then-honorable discharge. That would mean Stein would lose his benefits and would not be allowed on any military base.
The board's recommendations go to a general who will either accept or deny them. If the general disagrees with the board, the case could go to the secretary of the Navy.
Vote: Should Marine be kicked out?
Stein's lawyers argued that the 9-year Marine, whose service was to end in four months, was expressing his personal views and exercising his First Amendment rights.
"We're truly surprised and disappointed but it was an honor to fight for a hero like Sgt. Stein and every other Marine's right to speak freely," Stein's defense attorney Marine Capt. James Baehr said.
Free speech groups line up to back Tea Party Marine
Stein addressed board members during Thursday's hearing, telling them he loved the Marine Corps and wanted to re-enlist, Baehr said.
During the hearing, the prosecutor, Capt. John Torresala, said Stein went as far as superimposing images of Obama's face on a poster for the movie "Jackass."
Torresala argued that Stein's behavior repeatedly violated Pentagon policy that limits the free speech rights of service members, and said he should be dismissed after ignoring warnings from his superiors about his postings.
The government submitted screen grabs of Stein's postings on one Facebook page he created called Armed Forces Tea Party, which the prosecutor said included the image of Obama on the "Jackass" movie poster. Stein also superimposed Obama's image on a poster for "The Incredibles" movie that he changed to "The Horribles," the prosecutor said.
Security clearance removed
Torresala also said anti-Obama comments by Stein that were posted on a Facebook page used by Marine meteorologists were prejudicial to good order and discipline, and could have influenced junior Marines.
Stein's security clearance was taken away and he has no future in the Marine Corps because he can't do his job without that clearance, Torresala said.
"The Marine Corps community views the command's lack of action as some kind of knock on good order and discipline," Torresala said. "Our own people are questioning why this Marine is not being held accountable."
Baehr said during the hearing that prosecutors were trying to dredge up any damaging information they could against Stein.
"There is no basis in this case," Baehr said. "Sgt. Stein has broken no law."
Baehr expressed after the hearing that he hoped that the recommendation would be rejected by the general, saying the case will go forward. "The issues are too important for this to end today," he said.
The military has had a policy since the Civil War of limiting the free speech of service members, including criticism of the commander in chief.
Pentagon directives say military personnel in uniform cannot sponsor a political club; participate in any TV or radio program or group discussion that advocates for or against a political party, candidate or cause; or speak at any event promoting a political movement.
Commissioned officers also may not use contemptuous words against senior officials.
'Dangerous'
Backed by a team of lawyers and congressmen, Stein has said he is fighting for his constitutional rights and should be allowed to stay in the military. His lawyers and the American Civil Liberties Union contend his views are protected by the First Amendment.
"Think about how dangerous this could be if the U.S. government can prosecute you for something you say on your private Facebook page," Baehr said.
Stein has said his opinions are his own and has put a disclaimer on his Facebook page saying so. His attorneys argued service members have a right to voice their opinions as long as they do not appear to be presenting their views as being endorsed by the military. They say the Pentagon policy is vague and military officials do not understand it.
The Marine Corps has said it decided to take administrative action after Stein declared on Facebook that he would not follow orders from Obama and later clarified that statement saying he would not follow unlawful orders.
Stein could face other-than-honorable discharge while seeing his rank reduced to lance corporal and losing his benefits. The nine-year veteran was set to finish his service in four months.
Desk job
He said he was removed from his job at the Marine Corps Recruiting Depot in San Diego last month and given a desk job with no access to computers.
Rep. Duncan Hunter, R-Calif., a former Marine, wrote a letter to Stein's commanding officer stating the sergeant should not face dismissal for an opinion shared by a majority of Marines.
Hunter said he was referring to Stein's statement that he would not obey unlawful orders. Rep. Darrell Issa, R-Calif., also expressed support for Stein.
Stein said his statement about Obama was part of an online debate about NATO allowing U.S. troops to be tried for the Quran burnings in Afghanistan.
In that context, he said, he was stating that he would not follow orders from the president if it involved detaining U.S. citizens, disarming them or doing anything else that he believes would violate their constitutional rights.
