gyrogeerloose writes "During its last mission, astronauts from the Space Shuttle Atlantis installed an Automatic Identification System antenna on the outside of the International Space Station that will allow astronauts aboard the ISS to monitor signals from the AIS transmitters mandated to be installed on most large ocean-going craft. Although these VHF signals can be monitored from the Earth's surface, their horizontal range is generally limited to about 75 km (46 mi), leaving large areas of the ocean unwatched. However, the signals easily reach the 400 km (250 mi) orbit of the ISS. The European Space Agency sees this experiment as a test platform for a future AIS-monitoring fleet of satellites that will eventually provide worldwide coverage of sea traffic."

DesScorp writes "Aviation Week reports that the USAF has confirmed the existence of a new, formerly secret stealth aircraft, designated RQ-170 Sentinel, developed at Lockheed's legendary Skunk Works. Rumors of a secret new jet have been flying since 2007, with longtime aviation journalist Bill Sweetman dubbing the possible aircraft 'The Beast of Kandahar' because of the urban legend-like reports from Afghanistan. The aircraft is a UAV, a pilot-less drone that appears to have some kind of reconnaissance-only mission for the time being. It's a tailless flying wing that resembles a fighter-sized B-2 bomber."

TopSpin writes "BMW's limited roll out of the electric version of its Mini has met with complaints from early adopters including less than advertised range, cold weather charging problems, bulky batteries and connection issues. Richard Steinburg, BMW's manager of electric vehicle operations, assures everyone that the manufacturer is 'learning quite a bit as we go.' Drivers are paying $850/month for the privilege of helping BMW learn how to build EVs, while also helping BMW meet alternative fuel mandates so that other models can continue to be sold in select markets."

eldavojohn writes "With the problem of moving conventional rocket fuel to the Moon and Mars on their minds, researchers from Purdue and Penn State successfully tested and demonstrated the use of aluminum-ice (ALICE) as fuel. In a paper from last August they outlined how it would work (PDF), and now they know it does. Space.com also has more information on the paper and how nano-scale aluminum functions as a fuel."

Last year we ran the story of Yves Rossy and his DIY jetwings. Yves spent $190,000 and countless hours building a set of jet-powered wings which he used to cross the English Channel. Rossy's next goal is to cross the Strait of Gibraltar, from Tangier in Morocco and Tarifa on the southwestern tip of Spain. From the article: "Using a four-cylinder jet pack and carbon fibre wings spanning over 8ft, he will jump out of a plane at 6,500 ft and cruise at 130 mph until he reaches the Spanish coast, when he will parachute to earth." Update 18:57 GMT: mytrip writes: "Yves Rossy took off from Tangiers but five minutes into an expected 15-minute flight he was obliged to ditch into the wind-swept waters."

newscloud writes "Writer Evan Ratliff tells how he managed to hide from crowdsourced searchers for 27 days. The first person to find him and photograph him would claim a $5,000 prize. In addition to hiding out as a roadie with indy band 'The Hermit Thrushes' for a week, Ratliff donned a variety of increasingly impressive disguises. It's an interesting read on how to disappear in the digital age: 'August 13, 6:40 PM: I'm driving East out of San Francisco on I-80, fleeing my life under the cover of dusk. Having come to the interstate by a circuitous route, full of quick turns and double backs, I'm reasonably sure that no one is following me. I keep checking the rearview mirror anyway. From this point on, there's no such thing as sure. Being too sure will get me caught. About 25 minutes later, as the California Department of Transportation database will record, my green 1999 Honda Civic, California plates 4MUN509, passes through the tollbooth on the far side of the Carquinez Bridge, setting off the FasTrak toll device, and continues east toward Lake Tahoe. What the digital trail will not reflect is that a few miles past the bridge I pull off the road, detach the FasTrak, and stuff it into the duffle bag in my trunk, where its signal can't be detected. There will be no digital record that at 4 AM I hit Primm, Nevada, a sad little gambling town about 40 minutes from Vegas, where $15 cash gets me a room with a view of a gravel pile...' Spoiler alert: We previously discussed the denouement of the contest."

1sockchuck writes "Virginia's new state IT system is experiencing downtime in key services because of a mind-boggling oversight: the state apparently neglected to require network backup in a 10-year, $2.3 billion outsourcing deal with Northrop Grumman. The issue is causing serious downtime for state services. This fall the Virginia DMV has suffered 12 system outages spanning a total of more than 100 hours, and downtime hampered the state transportation department when a state of emergency was declared during the Nov. 11 Northeaster."

MikeChino writes "The much-hyped Solar Impulse airplane just completed its first runway test, paving the way for a 20-to-25-day trip around the world next year. Conceived by Bertrand Piccard, the single-pilot plane successfully used its four solar powered motors to taxi around the runway. If all goes according to plan the plane will be able to fly day and night without fuel, signaling a bright future for solar-powered flight."

Hugh Pickens writes "Increasingly, the military is deploying unmanned aerial vehicles, or UAVs, as eyes in the sky to scan the ground for targets and threats, especially for missions that are too dangerous for manned aircraft. Now Live Science reports that a new robotic spy plane called 'Ion Tiger' will harness alternative energy to make it more covert and longer lasting than battery-powered or engine-powered UAVs. A 550-watt, 0.75 horsepower hydrogen fuel cell will power the Ion Tiger with four times the efficiency of a comparable internal combustion engine and seven times the energy of the equivalent weight of batteries. When Ion Tiger took flight in October, it exceeded any demonstration of electrically powered flight so far, flying 23 hours and 17 minutes. 'And it carried a 5 lbs. payload to boot — enough to carry, say, a day-and-night camera,' says researcher Karen Swider-Lyons, head of the alternative energy section at the Naval Research Laboratory in Washington. 'No one has come close to flying 24 hours with a significant payload before.' Another big advantage is the Ion Tiger's reduced noise, heat and emissions. 'Think about lawnmowers or chainsaws — they're really loud,' says Swider-Lyons. 'It's hard to spy on people when they know you're there, so you had to fly them at high altitudes to keep them from being heard.'"

cheeks5965 writes "We've argued before over compressed air vehicles, a.k.a. air cars. Air cars are an enchanting idea, providing mobility with zero fuel consumption or environmental impacts. The NYTimes' Green Inc. blog reports that the reality is less rosy. New research from UC Berkeley and ICF International puts a period at the end of the discussion, showing that compressed air is a very poor fuel, storing less than 1% of the energy in gasoline; air cars won't get you far, with a range of just 29 miles in typical city driving; and despite appearing green the vehicles are worse for the environment, with twice the carbon footprint as gasoline vehicles, from producing the electricity used to compress the air. Given these barriers, manufacturer claims should definitely be taken with a grain of salt."

seven of five writes with this excerpt from an Associated Press report: "A problem with the FAA system that collects airlines' flight plans caused widespread flight cancellations and delays nationwide Thursday. It was the second time in 15 months that a glitch in the flight plan system caused delays. The FAA said in a statement that it is having a problem processing flight plan information. 'We are investigating the cause of the problem,' the agency said. 'We are processing flight plans manually and expect some delays. We have radar coverage and communications with planes.'"

CNet reports on hearings scheduled to open tomorrow in the US Senate on mysterious charges on thousands of consumers' credit cards. The Senate Committee on Commerce, Science and Transportation has been investigating online loyalty programs, which shoppers encounter (often with little comprehension) on the sites of online retailers such as as Continental Airlines, FTD, and Classmates.com. "At the center of the federal probe are Webloyalty, Affinion, and Vertrue, companies that make 'cash-back' and coupon offers to consumers and charge them monthly fees to enroll in their loyalty programs. ... In August, as the government's investigation rolled on, Webloyalty announced that it would alter its ads to require that consumers 'enter the last four digits of their credit or debit card to confirm' they wish to pay the membership fees. Last week, Affinion made similar changes. During the hearing, when the Senate committee is expected to make public the results of a six-month investigation, it will also likely say the alterations made by Webloyalty and Affinion don't go far enough. "

bridgeco writes "Chicago Traffic Court Judges have been throwing out speeding cases in which the driver's speed was measured with a LIDAR. Judges are asking for a special 'Frye Hearing' to determine the accuracy of these devices. Many motorists nabbed for speeding by a laser gun, instead of radar, are seeing their tickets thrown out at Chicago's traffic court because of a legal issue that the city's law department has been unable to overcome. Within the past year judges in Cook County Traffic Court in Chicago determined that speeds captured by lidar were not admissible because the devices had not been proven scientifically reliable in an Illinois court, said Jennifer Hoyle, spokeswoman for the law department, which prosecutes most speeding tickets in the city." (Here's some background on LIDAR from Wikipedia.)

clickclickdrone writes to mention that "road trains," a system linking vehicles together via wireless sensors, could soon be rolled out in Europe. The system is designed primarily for cutting fuel consumption, travel time, and congestion. "Funded under the European Commission's Framework 7 research plan, Sartre (Safe Road Trains for the Environment) is aimed at commuters in cars who travel long distances to work every day but will also look at ways to involve commercial vehicles. Tom Robinson, project co-ordinator at engineering firm Ricardo, said the idea was to use off-the-shelf components to make it possible for cars, buses and trucks to join the road train."

TechnologyResource writes "More than two years ago in California, a police officer wrote Shaun Malone a ticket for going 62mph in a 45-mph zone. Malone was ordered to pay a $190 fine, but his parents appealed the decision, saying data from a GPS tracking system they installed in his car to monitor his driving proved he was not speeding. What ensued was the longest court battle over a speeding ticket in Sonoma county history. The case also represented the first time anyone locally had tried to beat a ticket using GPS. The teen's GPS pegged the car at 45 mph in virtually the same location. At issue was the distance from the stoplight — site of the first GPS 'ping' that showed Malone stopped — to the second ping 30 seconds later, when he was going 45 mph. Last week, Commissioner Carla Bonilla ruled the GPS data confirmed the prosecution's contention that Malone had to have exceeded the speed limit and would have to pay the $190 fine. 'This case ensures that other law enforcement agencies throughout the state aren't going to have to fight a case like this where GPS is used to cast doubt on radar,' said Sgt. Ken Savano, who oversees the traffic division. However, Commissioner Bonilla noted the accuracy of the GPS system was not challenged by either side in the dispute, but rather they had different interpretations of the data. Bonilla ruled the GPS data confirmed the prosecution's contention that Malone had to have exceeded the speed limit."

Uncle Rummy writes "A central traffic control computer in Montgomery County, Maryland failed early Wednesday morning, leading to widespread gridlock across the entire county. The computer, which dates to the 1970s, is the single point of unified control for all traffic signals in the county, which comprises a number of major Washington DC-area suburban communities. When the system failed, it caused all signals to default to stand-alone operation, rather than the highly-tuned synchronization that usually serves to facilitate traffic flow during rush hours. The resulting chaos is a yet another stark reminder of how much modern civilization relies on behind-the-scenes automation to deliver and control basic services and infrastructure. The system remains down Thursday, with no ETA in sight."

coondoggie writes "The Federal Communications Commission and the US Department of Transportation are teaming up to develop what they called high-tech solutions to the growing problem of distracted or inattentive drivers. The DOT and FCC said they will set up a working group to evaluate technology-based answers to the distracted driving problem and will improve outreach efforts to educate the public about the dangers of texting while driving, talking on cell phones while driving, and other distracting behavior that can lead to deadly accidents, the agencies stated." Meanwhile, Korea has overturned a ban on dashboard TV-watching for taxi drivers.

cyclocommuter writes "Some Toyota owners are up in arms as they suspect that accidents have been caused by some kind of glitch in the electronic computer system used in Toyotas that controls the throttle. Refusing to accept the explanation of Toyota and the federal government (it involves the driver's-side floor mat), hundreds of Toyota owners are in rebellion after a series of accidents caused by what they call 'runaway cars.' Four people have died." The article notes: "The National Highway Traffic Safety Administration has done six separate investigations of such acceleration surges in Toyotas since 2003 and found no defect in Toyota's electronics."

Velcroman1 writes 'Taking a cue from the Terminator films, the US Navy is developing unmanned drones that network together and operate in 'swarms.' Predator drones have proven one of the most effective — and most controversial — weapons in the military arsenal. And now, these unmanned aircraft are talking to each other. Until now, each drone was controlled remotely by a single person over a satellite link. A new tech, demoed last week by NAVAIR, adds brains to those drones and allows one person to control a small squadron of them in an intelligent, semiautonomous network.'

holy_calamity writes "A team at Carnegie Mellon University has begun a project seeking to design a kit to cheaply convert secondhand cars into cheap, electric ones suitable for commuting, if little else. They hope to rely heavily on smart management software to extract as much efficiency as possible from regenerative braking, and knowledge of terrain from GPS tracking. But they are hampered by a lack of public data on how commuters actually drive. Their solution is to appeal to GPS users to upload .gpx log files of their commute to the team's site. The data is plugged into a simulator that reveals how much cheaper an electric car could do your journey, and an anonymized public dataset will be created. A programming contest will award a production electric car to the coder who designs the best management algorithm using it."
