In the desert miles outside of Las Vegas, a large white tube stretches for one third of a mile, and what happens inside could revolutionize travel. What if you could get to cities hundreds of miles apart in minutes instead of hours?Virgin Hyperloop One says this is no pipe dream.Dr. Anita Sengupta leads the team to make the technology come together. At their last speed test in the tube, she says their pod traveled 240 miles per hour, limited only by the length of the track. At top speeds, Sengupta says the Hyperloop is expected to travel at about 700 miles per hour. That, she said, means Hyperloop is not science fiction. “It is science fact because you can see it right here.” She spent most of her career working at NASA but brought her expertise back down to earth to help make Hyperloop a reality. This project reminds her of working on spacecraft. “I’m used to working with vacuum systems,” she said. “I’m used to working with electromagnetic propulsion.”How does Hyperloop work?Sengupta said the Hyperloop also uses a vacuum system. An electromagnetically propelled pod, designed to fit nine to twelve people, would levitate and travel through a vacuum tube. Between the levitation and vacuum system, she said the ride would remind people of an airplane but better. “There is no such thing as turbulence, right? Because you actually have no air around you on the outside of the pod so the ride is actually going to be much smoother,” she said. “You’re not even going to be able to tell you’re going that fast.” When will it be ready?“We would like to have them operational within the next two to three years,” said Sengupta.  1686

It seems people are not letting the coronavirus pandemic damper their holiday spirit as more than 3 million travelers took to the skies the weekend before Christmas.According to The Transportation Security Administration daily tally tracker, 1,064,619 people flew on Sunday, 1,073,563 traveled on Saturday, and 1,066,747 were screened on Friday.This marks the first time since March 16 that checkpoint numbers were over 1 million on consecutive days.Despite an increase in travelers, the amount of Americans traveling before Christmas was nowhere near the amount that traveled the weekend before Christmas last year - that weekend, TSA screen 7.6 million Americans.The surge in travelers comes despite the Centers for Disease Control and Prevention advising Americans to stay home and not travel during the holiday to slow the coronavirus spread. 854

It will cost a little less to buy Obamacare coverage in 2019.The average premium for the benchmark silver plan will decline by 1.5%, the Centers for Medicare & Medicaid Services said Thursday.It's the first time average premiums have fallen since the Affordable Care Act exchanges opened in 2014 — but the decline comes after a 37% spike for this year's benchmark silver plan.Americans who buy those plans will save a month over this year's rate, on average, but will still be paying 5 more a month than in 2017.Premiums vary across the 39 states that use the federal exchange. The biggest drop will be in Tennessee, where premiums will fall by more than 26%.The vast majority of Obamacare enrollees are not affected by annual premium changes because they receive federal subsidies to offset the cost. 819
