High Speed Acceleration and Braking Test on the Radar for Elon Musk's Hyperloop

Tech billionaire Elon Musk plans hyperloop high-speed acceleration and braking test

A passenger pod would try to reach half the speed of sound,roughly 381 miles an hour, and then brake in less than a mile, Musk tweeted in the tech billionaire's latest update. The announcement came as competitors, including British tycoon Richard Branson, pursue rival hyperloop plans.
 From article, (The Tesla and SpaceX CEO says his companies' upgraded hyperloop transportation pod will undergo a test soon — with the aim of reaching half the speed of sound and then braking in less than a mile.

In a late Saturday night tweet, Musk teased the latest progress update in his effort to build a tunnel capable of whisking pods of travelers between cities at speeds of up to 700 miles per hour. 

The upcoming test will try to have the pod achieve half the speed of sound, or roughly 381 miles per hour, and then brake within 1.2 kilometers, or approximately three-quarters of a mile, he tweeted.

Musk first introduced his vision for a tube-based hyperloop transportation system in a 2013 white paper, outlining the possibility of a gridlock-busting idea that could make current modes of transit passe.

In the years since, Musk has gained several potential hyperloop competitors, including British tycoon and airline magnate Richard Branson. In February, the Branson-backed Virgin Hyperloop One announced plans to build a hyperloop tunnel in India that would lop roughly three hours off the travel time between the city of Pune and a planned airport in Mumbai.

Last week, a Canadian startup called TransPod said it wants to raise $50 million for its own hyperloop technology aimed at ferrying passengers at speeds of more than 1,000 kilometers or roughly 622 miles an hour, Bloomberg News reported.

Musk hasn't exactly been standing still. In October, the American Public Transportation Association tweeted that Musk was poised to a start a hyperloop project in Maryland. The tweet cited a Baltimore Sun report that said state officials had issued a conditional utility permit to let Musk’s tunneling firm, The Boring Company, dig a 10.3-mile tunnel beneath the Maryland-owned portion of the Baltimore-Washington Parkway

Separately, Musk used a series of tweets in March to refine his futuristic transportation vision. The tweets included an animation that showed a bus-like vehicle suddenly lowering itself deep underground where it joined a flowing artery filled with similar people-filled pods.

Musk described the new auto-less mission as a departure from his original concept for The Boring Company, which focuses on drilling tunnels beneath major urban centers. Initially, he planned to fill the company's tunnels with moving platforms that carried passengers' personal cars.)

New Tool For BFR Revealed.

SpaceX appears ready to spin carbon fiber for the BFR spaceship

Elon Musk has been talking about SpaceX's large BFR rocket for a few years, but so far we've seen precious little hardware. In 2016, Musk showed off a large, composite fuel tank that will contain pressurized liquid oxygen. The company has also shared limited video of the rocket's Raptor engines.

Now, as SpaceX moves forward with a facility to manufacture the rocket in Long Beach, Calif., we probably will see more hardware associated with the BFR—known as the Big Falcon Rocket in polite circles. To that end, on Sunday night, Musk shared a photo of a tooling that will be used to make carbon-fiber composites for the rocket's upper stage, the spaceship. This appears to be a mandrel, or mold, around which carbon fiber is wound for the main body of the spaceship, or BFS.

 This new tooling indicates that remains a possibility. SpaceX has a notional goal of launching the first BFR to Mars in 2022. We doubt that will happen, but now we are more certain that someday the massive booster will take flight.)
