For anyone who used to play with slot cars as a child, Sweden's new electrified road might bring back some memories.In the first of its kind, the Scandinavian country is trialling the world's first public road which allows electric vehicles to recharge while driving. Similar to a slot-car track, vehicles are able to connect to an electric rail that's embedded into the road.Sweden has a goal of achieving a completely fossil fuel free vehicle fleet by 2030, so this electrified road is part of several projects the Swedish Transport Administration has created to develop and test technologies that may be able to help the country reach its target.In this particular project, 'eRoadArlanda', electricity is transferred via a movable arm that attaches to the tracks built into the middle of the road. While the system is designed with the capacity to feed heavier vehicles such as trucks, it's also developed to work for cars and buses.When vehicles approach the track, a sensor from the car or truck detects the electrified rail and the movable arm lowers from underneath the vehicle and inserts into the rail. The arm has been designed to be flexible, providing the car, or truck, the freedom to move around the road without disconnecting."One of the most important issues of our time is the question of how to make fossil-free road transportation a reality," Hans S?ll, chairman of the eRoadArlanda says."We now have a solution that will make this possible, which is amazing. Sweden is at the cutting edge of this technology, which we now hope to introduce in other areas of the country and the world."The track stretches along two kilometers (1.2 miles) and has been installed on public road "893" just 30 minutes outside of Stockholm.The eRoad has many advantages, S?ll says. If implemented it will mean electric vehicle batteries can be smaller -- and therefore lighter -- because they won't need to retain as much charge, the vehicles will then be cheaper to manufacture and will ultimately be more sustainable.For a heavy truck to be 100% electric, he explains, it would need a battery that weighs 40 tonnes. But if technology like the eRoad was readily available, the truck's battery would be able to weigh as little as 600 kilograms.It would also fix a wider issue that many electric vehicle owners face: The worry and inconvenience of keeping vehicles charged."Today you're not 100% sure how far you can go with your battery but if you have a combination of electric roads you will feel a little bit more confident that you'll get where you want to go," S?ll says.The technology is also safe and adverse weather such as rain, snow and ice should not cause any major issues thanks to draining and usual maintenance. The electricity also isn't a risk to humans or animals."There's no electricity at the surface and the rail is only electrified if an actual authorized vehicle is passing, so if you don't have an electric vehicle that's authorized to use the electricity, the electricity will not be turned on at all -- it will not be on 24/7."There will also be plenty of signage around the area indicating the road is electrified and the system is equipped with safety circuits.S?ll says while the new project cost €6.4 million (.7 million) to develop, if it were more widely implemented across the country it would eventually work out less than €1 million (.2 million) per kilometer to build.That is, if the government decides to implement it nationally."The Government wants to test one or two additional technologies ... that will then be evaluated in two years or so, (and) after that they will pick out one of those technologies (that have been tested) to build a longer pilot stretch that will be between 20 and 40 kilometers," he says.For now, the eRoad will be used and trialled for two years by a truck carrying freight in order to determine how well the innovation works under various weather conditions and in conjunction with normal road traffic.The-CNN-Wire 3992

First of all, let's be clear: Every dog is the best dog, especially yours. But unfortunately, it looks like your drooling, howling, underwear-sniffing, sock-eating angel of perfection is not, you know, especially smart.This distressing news comes?from a new study in the journal Learning & Behavior, which seeks to answer the question, "Are dogs really that special?"While our hearts say yes, the data says no.The study compares canine cognition to other carnivores, social hunters and domestic animals (all groups that dogs fall into). Researchers used existing information on the behavior of several animals, including wolves, cats, dolphins, chimpanzees, pigs and pigeons to see if dogs possessed any special skills that weren't recorded in other species.They did not. 779

Former Obama administration official and San Antonio Mayor Julian Castro said he is "likely" to challenge President Donald Trump in 2020."I'm likely to do it. I have a strong vision for the country. I believe that our country's going in the wrong direction and that it needs new leadership. I'll make a final decision after November, but I'm inclined to do it," Castro said in an interview published by Rolling Stone on Tuesday.Castro, who was the secretary of housing and urban development during the Obama administration, has stoked speculation about his presidential ambitions in a series of public comments and with increasingly frequent travel to presidential primary states. He had been rumored to be a contender for the vice presidential spot on the 2016 Democratic ticket.Over the weekend, the Texas Democrat was in Iowa campaigning for J.D. Scholten, a candidate for Iowa's 4th Congressional District. It was Castro's second trip to the state since August"You know, I have to say, I felt at home coming in, walking in," Castro told a crowd at the event. In late July, Castro's twin brother, Democratic Rep. Joaquin Castro of Texas, told CBS that his brother has "definitely thought about it," referring to a presidential bid.Speaking to Rolling Stone, Julian Castro expressed some hesitation about a 2020 bid, citing his family, but he also began articulating the basis of a run.He was also asked about a potentially bruising Democratic primary fight amid signs that key contenders like Joe Biden and Elizabeth Warren are preparing to declare their own presidential ambitions."It's going to be cathartic for the party to go through a process where everybody gets to show what they've got. Where you have debates with over a dozen people and every wing of the party is represented," Castro said.He continued, "We need to go through that to get over 2016, and we're going to come out of the 2020 primary, I'm convinced, in a much stronger position. The nominee will be stronger for it and be better prepared to win in November of 2020. I'm hopeful, and I think realistically hopeful, about what this very contested, long, drawn-out process is going to mean. Most of the time a party wants to avoid that kind of process, but in this case, that's our salvation." 2285

FREDERICK, Colo. ¡ª Newly released court documents in the Chris Watts case obtained by KMGH suggest his two young daughters may have been strangled.The suggestion came in a motion filed by defense attorneys in Weld County court to compel the coroner to take DNA from the necks and throats of the remains of 4-year-old Bella and 3-year-old Celeste Watts, whose bodies were found inside oil and gas tanks Thursday. The court document also said the bodies were submerged in crude oil for four days.The bodies of the two young girls were found in close proximity to the other body positively identified as Shanann Watts, the girls¡¯ mother.In the motion filed Friday, DNA expert Richard Eikelenboom concludes that DNA evidence ¡°would remain on the necks of the decedent children,¡± after they were submerged in the oil. Eikelenboom is quoted in the motion as saying he believes the oil would not eliminate DNA and said samples can be obtained "after strangulation."The motion also asks that DNA samples be taken from the hands and nails of the body of the girls' mother.Eikelenboom writes:¡°This DNA can be retrieved with a double swab technique. DNA scientists are familiar with this technique and an experienced person should take this samples. In my opinion the presence of oil will not destroy the DNA. The hands wand nails of the mother should be sampled as well. After samples are taken the nails should be cut preserved. I have a lot experience taking samples from dead bodies getting good results after strangulation. The hands of the children should be sampled as well.¡±Eikelenboom is a forensic scientist who has claimed to be a DNA expert in trials in Colorado and across the United States, but was discredited two years ago in a 2013 sex assault case in Denver District Court.¡°I would be shocked if the defense tried to use him front of a jury after he has been discredited as an expert witness,¡± said former Denver District Attorney Mitch Morrissey, who led the charge against Eikelenboom.The motion was dismissed by the judge.On Friday, the coroner's office announced they have positively identified the victims of the Frederick case as Shanann Watts and her two daughters. The manner and cause of death of all three bodies are pending further laboratory results and will not be released at this time.Chris Watts remains in the Weld County Jail on suspicion of murder his family. He was taken to jail at 11:30 p.m. Wednesday after he was detained for questioning. Two law enforcement sources told KMGH Watts had confessed to killing his wife and daughters. He faces investigation on one count of first-degree murder after deliberation; two counts of first-degree murder ¨C position of trust; and three counts of tampering with a deceased human body.All three were reported missing Monday around 2 p.m. after Shanann did not arrive to a scheduled meeting. In addition to having two daughters, Shanann was also 15 weeks pregnant. The FBI and CBI were brought in to help Frederick police in the investigation.Weld County prosecutors said they believe Shanann and the girls were killed inside of the family¡¯s home but did not say why they believe that. 3241
