B. Don Russell wasn’t thinking about preventing a wildfire when he developed a tool to detect power line problems before blackouts and bigger disasters.The electrical engineering professor at Texas A&M University figured he might save a life if his creation could prevent someone from being electrocuted by a downed live wire.But fire prevention may be his product’s biggest selling point in California and other places that have experienced devastating wildland blazes blamed on electrical equipment.“If we can find things when they start to fail, if we can find things that are in the process of degrading before a catastrophic event occurs, such as a downed line that might electrocute someone or a fire starting or even an outage for their customers, that’s kind of the Holy Grail,” Russell said.The technology he bills as a one-of-a kind diagnostic tool called Distribution Fault Anticipation is now in use in Texas and being tested in California by Pacific Gas & Electric Co. and Southern California Edison. The utilities have been blamed for some of the most destructive and deadliest fires in California.Texas A&M said the technology will also be tested in New Zealand and Australia, which is currently reeling from destructive wildfires.The tool detects variations in electrical currents caused by deteriorating conditions or equipment and notifies utility operators so they can send a crew to fix the problems, Russell said.It can anticipate many problems in their early stages — sometimes years before they cause an outage or present a greater hazard during high winds when utilities are now pre-emptively shutting off power to prevent sparking wildfires.Before the technology was developed, electric companies often didn’t know they had a problem until there was a failure or a customer called to report sparks on power lines or a loss of electricity.“The assumption the utility has to make today is it’s healthy until we get a call that says somebody’s lights (are) out,” Russell said. “By then the fire’s started or the outage has happened or the person’s electrocuted.”Pedernales Electric Cooperative Inc. that serves about 330,000 customers outside San Antonio and Austin, Texas, began implementing the system after successful tests that began in 2015. The utility serves areas so rural that before the technology was installed, electricity powering a pump on a well could have been off for days before being detected by a farmer.The devices installed at substations are now trouble-shooting all kinds of problems, said Robert Peterson, principal engineer for the utility.“We’ve found tree branches on the line. Failing arrestors. Failing capacitors. Failing connections,” Peterson said. “It’s pretty amazing.”In California, the testing process has just begun and there are no results yet, according to PG&E and SoCal Edison.In Southern California, the software is running on just 60 of Edison’s 1,100 circuits in the utility’s high-risk fire zone, which accounts for about a quarter of its total circuits.It’s just one of several tools the utility is testing to continue to modernize its system.“There is no silver bullet,” said Bill Chiu, managing director of grid modernization and resiliency at SoCal Edison. “This is really more of a preventive measure. ... The important point is this will be one of the suite of technology that will help us better assess the condition of the grid.”Chiu said the technology was not at the point where it could be used to determine where to shut off power when dangerous winds are forecast during dry conditions. He also said it won’t pinpoint problems but can help dispatch crews closer to the source of equipment that needs to be fixed, saving time that would be wasted patrolling miles of power lines.One question is whether the technology is economically feasible to deploy across tens of thousands of miles of power lines, Chiu said.At an expense estimated between ,000 to ,000 per circuit, it could cost the utility million in its high-risk fire area and that doesn’t include installation, operation and maintenance costs.That’s a fraction of what a moderate wildfire sparked by a utility could cost, Russell said.PG&E, which is testing the technology on nine circuits, was driven into bankruptcy protection this year while facing at least billion in losses from a series of deadly and destructive wildfires in 2017 and 2018.SoCal Edison recently agreed to pay 0 million to local governments to settle lawsuits over deadly wildfires sparked by its equipment during the last two years. That figure doesn’t include lawsuits by thousands who lost their homes in those fires or family members of 21 people killed when a mudslide tore down a fire-scarred mountain. Two other people were never found.Bluebonnet Electric Cooperative found the cost was feasible and has installed it on about a sixth of its circuits for the utility that has about 100,000 customers in Central Texas, said Eric Kocian, chief engineer and system operations officer.While the system has helped proactively diagnose problems and detect the cause of outages, the university team that developed it can often find problems the utility’s control room operators don’t detect.Pedernales Coop is working with an analytics company to streamline the analysis of the myriad information the software evaluates to find and fix problems in a day, Peterson said.Russell said he never had a hint the device his research team created 15 years ago would have fire prevention applications until a series of bad wildfires in Texas in 2011. They were focused on keeping power systems safe and the lights on.“It’s obvious now in today’s context of the drought that we’ve had in California and other places,” Russell said. “Serendipitously, that’s where we find ourselves today.” 5838

Boeing employees knew about problems with flight simulators for the now-grounded 737 Max and apparently tried to hide them from federal regulators, according to documents released Thursday.In internal messages, Boeing employees talked about misleading regulators about problems with the simulators. In one exchange, an employee told a colleague they wouldn’t let their family ride on a 737 Max.Boeing said the statements “raise questions about Boeing’s interactions with the FAA” in getting the simulators qualified. But said the company is confident that the machines work properly.“These communications do not reflect the company we are and need to be, and they are completely unacceptable,” Boeing said in a statement. Employees also groused about Boeing’s senior management, the company’s selection of low-cost suppliers, wasting money, and the Max.“This airplane is designed by clowns who in turn are supervised by monkeys,” one employee wrote.Names of the employees who wrote the emails and text messages were redacted.The Max has been grounded worldwide since March, after two crashes killed 346 people. The crash that month of an Ethiopian Airlines flight had been preceded in October 2018 by the crash of a brand-new Max operated by Indonesia’s Lion Air.Boeing is still working to update software and other systems on the Max to convince regulators to let it fly again. The work has taken much longer than Boeing expected.The latest batch of internal Boeing documents were provided to the Federal Aviation Administration and Congress last month and released on Thursday. The company said it was considering disciplinary action against some employees.An FAA spokesman said the agency found no new safety risks that have not already been identified as part of the FAA’s review of changes that Boeing is making to the plane. The spokesman, Lynn Lunsford, said the simulator mentioned in the documents has been checked three times in the last six months.”Any potential safety deficiencies identified in the documents have been addressed,” he said in a statement.A lawmaker leading one of the congressional investigations into Boeing called them “incredibly damning.”“They paint a deeply disturbing picture of the lengths Boeing was apparently willing to go to in order to evade scrutiny from regulators, flight crews, and the flying public, even as its own employees were sounding alarms internally,” said Rep. Peter DeFazio, D-Ore., chairman of the House Transportation Committee.DeFazio said the documents detail “some of the earliest and most fundamental errors in the decisions that went into the fatally flawed aircraft.” DeFazio and other critics have accused the company of putting profit over safety.The grounding of the Max will cost the company billions in compensation to families of passengers killed in the crashes and airlines that canceled thousands of flights. Last month, the company ousted its CEO and decided to temporarily halt production of the plane in mid-January, a decision that is rippling out through its supplier network. 3066

As computers, tablets and cellphones have become a growing part of our lives, the exposure to blue light emitted from these devices increases. While blue light exposure has been known to cause strain in eyes, Oregon State University researchers studied the effect of blue light exposure on aging. Based on to their findings, exposure to blue light could cause aging to accelerate. For their study, researchers used common fruit flies and exposed them to 12 hours of blue LED light and 12 hours of darkness. To compare, researchers kept a group of flies in total darkness, as well as a group of flies that were exposed to light that had the blue wavelengths filtered out. The researchers said they chose fruit flies because their cellular and developmental mechanisms are similar to humans.The researchers said that flies exposed to blue LED light sustained damage to their retinal cells and brain neurons and had impaired locomotion. Even more stunning, some of the flies, which exhibited some brain damage, were mutants that did not develop eyes."The fact that the light was accelerating aging in the flies was very surprising to us at first,” said Jaga Giebultowicz, a professor of integrative biology at Oregon State. “We’d measured expression of some genes in old flies, and found that stress-response, protective genes were expressed if flies were kept in light. "We hypothesized that light was regulating those genes. Then we started asking, 'what is it in the light that is harmful to them,' and we looked at the spectrum of light. It was very clear cut that although light without blue slightly shortened their lifespan, just blue light alone shortened their lifespan very dramatically.” 1708

As the coronavirus spread globally, a canceled work trip here and there turned into a worldwide shutdown for business travel by air.The global airline industry is now on the brink of collapse. And while pressing pause for a few days or a week is strange enough, a freeze on business-class travel that lasts for several weeks or months has the potential to reshape why people fly. After a decade of huge growth, airlines are preparing for a staggering drop in revenue worldwide. Concerns over the coronavirus have crippled demand for flights, which in turn has caused many airlines to ground their fleets and lay-off staff.Recently JetBlue CEO Robin Hayes called this financial situation for airlines, "at least as bad as 9/11 if not worse."But even with a bailout, it could take months for travelers to fully return to the skies. In the meantime, a lot of business will go on without air travel.With huge advances in telecommuting and a growing acceptance of working from home, businesses have taken to platforms like Slack, Zoom and Skype to carry on with meetings while many miles apart.To understand the impact of losing business class travel, you have to understand how valuable business class tickets are to airlines. It might just be a few seats, but on many flights, premium seats actually account for most of the money the flight will make. Let's explain.Let’s look at a roundtrip flight scheduled for the first week in August between JFK and LAX. The round trip fare for an economy passenger costs 9. For a business class passenger that seat is ,867. And finally for a first class passenger the cost is ,032. In total, if everyone pays full price for their ticket, the airline makes ,362.But notice the distribution. If you do the math, you see that although business and first class travelers only make up 28% of the passengers on the flight, they account for 60% of the flight's revenue. This model doesn't describe every flight. But when it comes to airline economics, business and first class passengers have an outsized impact on many airlines' revenue. "They care a lot about business class travelers," says airline pricing expert Andy Boyd. "The other part about the business class travelers is not just the seat but business travelers become very connected with their brand and they fly a lot. It’s not just the money they make from the one seat, but what they get over time."Boyd literally wrote the book on airline ticket pricing. He believes airlines could bounce back, but he also says the virus could accelerate some trends already in motion for business travel."It could be a catalyst," Boyd says. "But what is really interesting, the new generation has grown up with technology, with cell phones. The fact that you are doing what many older people would call, very informal communication is more and more accepted as formal communication. So as young people who have grown up with technology get older, they may find that they are just as happy doing things over the phone as they are getting on a plane and going somewhere."Those combined factors could spell long-term impacts for the airline industry beyond the spread of the coronavirus. "Normally I would tend to say we would just get over it and the world would just get back to normal," Boyd says. "But with this particular virus and the way that people have responded to it, we may see some actual real changes to the way that both business and economy travelers travel." 3474
