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

Fox News announced Friday that President Donald Trump has agreed to conduct his first on-camera interview since his COVID-19 diagnosis with conservative pundit Tucker Carlson.In addition to an interview with Carlson on his 8 p.m. ET show, Fox News reports that Trump will receive a "medical evaluation" from Dr. Marc Siegel, a physician and contributor to Fox News.Trump has not appeared live on camera since he walked out of Walter Reed Medical Center on Monday evening, though White House has released a series of recorded videos featuring the President.Trump's interview with Carlson will be the latest in a string of interviews with conservative media outlets friendly to the President. Trump called into Fox Business on Thursday morning and spoke with Fox News' Sean Hannity over the telephone on Thursday evening. Trump also conducted a lengthy appearance on talk show host Rush Limbaugh's radio program on Friday afternoon.At a few points during his interview with Hannity on Thursday night, Trump had to stop talking in order to cough, and at points sounded hoarse.Trump has said he would like to return to the campaign trail as early as Saturday, and White House doctors cleared him to do so in a letter released Thursday. Trump initially announced he had tested positive for COVID-19 in the early morning hours of Oct. 2, though White House officials have declined to make public the date of the President's last negative test.The Centers for Disease Control and Prevention say those with COVID-19 should remain quarantined until 10 days after symptoms first appear, but only after the patient has been free of fever for 24 hours (without the use of medication). 1680

Florida Gov. Rick Scott signed Senate Bill 7026 into law Friday, the first gun control legislation enacted in the state after the Parkland school massacre on February 14.The new law, known as the Marjory Stoneman Douglas High School Public Safety Act, tightens gun control in several ways but also allows some teachers to be armed."The hardest thing I've ever had to do as governor is try to console a parent who has lost a child," said Scott, surrounded by families of the victims. Scott received the bill Thursday following days of impassioned, often contentious debate in the majority-Republican House and Senate.  631

First it was catastrophic lava. Then it was sulfur dioxide. Now Big Island residents have yet another danger to worry about.Laze -- a mashup of "lava" and "haze" -- is a nasty product formed when hot lava hits the ocean, sending hydrochloric acid and volcanic glass particles into the air.And now it's a real threat after lava crossed Highway 137 late Saturday night and entered the Pacific Ocean, the Hawaiian Volcano Observatory (HVO) said.Laze can cause lung, eye and skin irritation. And it's proven deadly in the past."This hot, corrosive gas mixture caused two deaths immediately adjacent to the coastal entry point in 2000, when seawater washed across recent and active lava flows," the HVO said.Officials are warning people to stay away from areas where lava meets the ocean. But further inland, residents have other problems. 857

For the second time in two months, thousands of students from across the country are streaming out of class Friday as part of a National School Walkout to demand action on gun reform -- even as Florida police investigate a fresh shooting that injured a student Friday morning.Students are walking out of class at 10 a.m. in each time zone to observe a moment of silence for shooting victims.Before Friday's walkouts began, the latest school shooting happened in Ocala, Florida, northwest of Orlando. Police said a student was shot in the ankle at Ocala's Forest High School, and a suspect is in custody. 611
