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

Flint schools are finally getting the help they need to provide safe water fountains for their students.Flint Community Schools thanked billionaire Elon Musk and the Musk Foundation last week for donating money to install new water fountains with filtration systems at all its schools.Lead and other toxins were found to be tainting Flint's water supply four years ago, in what's been called the Flint water crisis. Since then, the community has struggled with water contamination problems."We are deeply grateful for the generosity and the budding partnership between Flint Community Schools, the Musk Foundation and Elon Musk," said Flint Community Schools Superintendent Derrick Lopez. "The new water filtration systems will be instrumental in helping our students return to the normalcy of what should be a fundamental right: having access to safe, clean water from water fountains in their school."Flint schools will install new ultraviolet water filtration systems for all its water fountains in school buildings thanks to the 0,350 donation, according to the city of Flint.The former Tesla CEO responded to the school's announcement on Twitter. "You're most welcome. Hope to do more to help in the future," he wrote.Musk first promised to help Flint in a tweet back in July. "Please consider this a commitment that I will fund fixing the water in any house in Flint that has water contamination above FDA levels. No kidding," he wrote at the time.The new fountains and filtration systems will be installed in all 12 Flint schools and the district's administration building by the end of January 2019."The UV water purification method within the water filtration systems will disinfect all lead and bacteria coming from the water pipes to allow students to drink from and fill up water bottles from school water fountains," the city of Flint said in a press release on October 5. 1896

Following a three-month break from the campaign trail, President Donald Trump told reporters from the White House pool on Wednesday that he is planning to resume campaign rallies soon.An exact date and location for upcoming rallies isn¡¯t available yet, but Trump said that he has visits to Oklahoma, Florida, Arizona, North Carolina on his schedule. Trump and rival Joe Biden were forced off the campaign trail in March as the coronavirus began to spread in earnest throughout the US.The CDC still recommends against large gatherings of 250 people or more,, and some states are still seeing an increase of coronavirus cases. One of those states is Arizona, where the state¡¯s governor has told hospitals to prepare to go over capacity as the state is seeing a surge in coronavirus-related hospital stays.Trump¡¯s announcement comes on the heels of reports that the Republican Party is planning on moving its convention to Jacksonville, Florida, from Charlotte, North Carolina, as the state¡¯s governor would not commit to lifting a ban on mass gatherings at the time of the August event. 1092

For many 5-year-old kids across the country, kindergarten is an exciting first introduction into the classroom. But this year, schools are grappling with growing COVID-19 cases and declining kindergarten enrollment numbers."In terms of our kinder cohort, we usually have about 23,000 students registered in Miami-Date County schools for kindergarten. Right now, as of this week, we have a total of 14,724 registered already for next year," said administrative director Berena Cabrera, with Miami-Date County Public Schools in Florida.Cabrera says the district is tackling a 40-percent decline in kindergarten enrollment, and other public schools across the country are dealing with a similar situation.At Visalia Unified School District in central California, kindergarten enrollment is down by 15 percent. At Poway Unified School District, near San Diego, they're seeing 5 percent less kindergarten students enrolling. Fulton County Schools in the Atlanta, Georgia area reports 12 percent less students are enrolled in kindergarten for the upcoming school year."Kindergarten is critical. It is the foundation of a successful student. And in Florida, it is mandatory for students to start kindergarten," said Cabrera.While kindergarten isn't mandatory in all states, educators agree it's an important beginning to a student's education. Rising coronavirus cases in communities combined with public schools having to tackle the virus head-on, has prompted some parents to turn to private kindergarten.Primrose Schools, which offers private daycare, preschool and kindergarten at more than 400 locations across the country, says they've seen a massive increase in interest, especially for those parents whose local districts are offering a virtual-only program this fall."Many of the working parents, obviously, they¡¯ve got to have childcare. Where they would have had before and after school care now they're going to need full day. So, what we¡¯ve seen is our schools responding rapidly by many of them opening up classrooms to kindergarten programs," Jo Kirchner, CEO of Primrose Schools, said.Kirchner says some of their locations are adding kindergarten classrooms to accommodate the increased interest. Their schools offer a 1:10 teacher to student ratio, plus heightened sanitation protocols."Even the parents who stay home with their children, who now find themselves virtual versus sending them to school, don¡¯t really have the skill sets to provide the academic learning support the children need,¡± Kirchner said. ¡°Kindergarteners have a fairly short attention span so distance learning is not the best environment for a kindergartner.¡±While kindergarten families across the country consider their options, Miami-Dade County Public Schools is converting a lot of their enrollment from paper to digital. Additionally, they're doing a big push on the district's website and social media."We¡¯re hopeful that registration does pick up in the coming weeks. We are rolling out with a major marketing campaign, and we¡¯re trying to let the parents know that there are staff in our schools that are registering," said Cabrera.Cabrera adds, whether kindergarten is in-person or remote learning this fall, she hopes parents will enroll their children for this crucial first start to their academic career. 3309

Former Milwaukee County Sheriff David Clarke is being criticized on social media after making homophobic comments while referencing the "locker room talk" war of words between President Donald Trump and former Vice President Joe Biden. Biden told a Florida crowd Tuesday that he would "beat the hell out of Trump" if they were in high school and Trump made lewd comments recorded during an Access Hollywood interview several years ago.Trump clapped back Thursday, calling Biden "mentally and physically" weak, and tweeting that Biden would "go down fast and hard, crying all the way." In a Wednesday tweet, Clarke zeroed in on Biden's comment that he's been around a lot of locker rooms in his life, and stated "Please tell us why and what you were doing hanging around all those locker rooms, Joe? Taking in the sights? Did the soap keep falling out of your hands Joe?" 888
