The Hyperloop Lives On As a 1/12th Scale Model In Switzerland (theverge.com) 34
Last December, Hyperloop One, the futuristic transportation company pursuing Elon Musk's dream of tube-based, airplane-speed travel, announced its shutdown. However, the concept itself has found a new lease on life in a scaled-down version overseas. According to The Verge's Andrew J. Hawkins, "The hyperloop, in fact, lives on -- as a 1/12th scale model in Switzerland." From the report: Sure, this isn't exactly the full realization of Musk's 2013 white paper, in which he theorized that aerodynamic aluminum capsules filled with passengers or cargo could be propelled through a nearly airless tube at speeds of up to 760mph. These tubes, either raised on pylons or sunk beneath the earth, could be built either within or between cities. Musk called it a "fifth mode of transportation" and argued it could help change the way we live, work, trade, and travel. The idea is being put to the test in Lausanne, Switzerland, where a 120-meter circular test track is being operated by a team that includes the Federal Institute of Technology Lausanne (EPFL), the School of Business and Engineering Vaud (HEIG-VD), and Swisspod Technologies. This week, the group announced that it had conducted "the longest" hyperloop test of its kind: traveling 11.8 km (7.3 miles) at a speed of 40.7km/h (25.3mph).
The circular test track has a circumference of 125.6 meters (412 feet) and a diameter of 40 centimeters (15.7 inches). It sounds modest, but the group claims that in a full-scale system, their test "directly translates" to a journey of 141.6 km (88 miles), which is about the distance between Geneva and Bern, or San Francisco to Sacramento, and speeds of up to 488.2 km/h (303.4mph). The project is called LIMITLESS, which stands for Linear Induction Motor Drive for Traction and Levitation in Sustainable Hyperloop Systems. During the test, the team "monitored the performance of vital subsystems," including propulsion, communication infrastructure, power electronics, and thermal management. They assessed "energy consumption, thrust variations, [linear induction motor] response, and control during acceleration, cruising, coasting, and braking scenarios."
Of course, a 1/12th-scale circular test track is hardly a sign that the hyperloop is alive and well. Most of the startups and companies pursuing a full-scale hyperloop have shut down, victims of financial mismanagement, as well as infrastructure and regulatory hurdles. Critics said that while the hyperloop may be technically feasible, it still only amounts to vaporware. It's been called a "utopian vision" that would be financially impossible to achieve. But the Swiss team is undeterred, promising to conduct a battery of future tests to further validate the system. Swisspod CEO Denis Tudor said the group plans to test its first freight product soon, and is currently building a larger test track in the US. "This is a key step toward making hyperloop for passengers a reality and changing how we connect, work, and live," he said.

We've seen from more ride-share companies that it doesn't really cut down on cars on the road, usually the opposite. People take the taxis instead of public transit if it's convenient/affordable enough. The vehicles aren't always going to have a passenger, it just doesn't work out that conveniently so they have to go somewhere between trips and have to travel to pick up people so it ends up more vehicles on the road

But imagine the logistics of this. First, people drive around the same time (rush hour) so the number of cars won't really diminish, it would just give an option to have them rented out instead of parked, but there would be a lot more cars than people that need them so the cars are either still going to be parked or are going to be driving around in traffic with no one in them.

This heavily depends on people staggering when they want to drive to/from work to give cars to drive to the busier destinations and back out to pick up the next fare and the reverse in the afternoon. Meanwhile the cars all have to go somewhere. Either to some parking facility locally or drive out to some remote facility. Ends up being probably twice the energy spent driving with half that being empty rides

While it's true that robotaxi concept doesn't reduce the number of cars driving around, 1/3 of the number of total cars does all that driving around.
Also, eventually, if the model takes hold, parking lanes can mostly be eliminated, so that would have a slight congestion reduction effect.

He actually wants fewer cars on the road, as evidenced by his pivot of Tesla toward being a robotaxi company.
What BS. Musk wants to sell cars. The H-L was Musk's alternative to railways and aircraft because he hates public transport except in small pods that he and his bodyguards would fill with no strangers present. Musk hates "strangers" and railways. He's now bored with cars and is moving into robots and politics, but his wealth is still in cars. The robotaxis will not revolutionise anything.

His company doing this stuff has first mover advantage, and innovates well, so it's also profitable. But that profitability is largely due to being one of the first to implement the post-energy-transition transportation architecture.

It's hard to see how car sharing would reduce the number of vehicles on the road. When a personal car isn’t being used, it’s typically parked in a garage or a parking spot, not occupying road space. The actual number of cars on the road is determined by how many people are commuting at any given time and how many passengers each car holds, not by who owns the vehicles. So, whether cars are individually owned or shared, the number of occupied cars on the road should remain about the same.

Don't think so. Taxis are not fewer cars on the road. Ride-share in the curent state has little to no "sharing", uber and lyft are essentially single trip taxis and not a transit service. Right now uber and lyft drivers are on the road, driving around, waiting for the phone to ding to go pick someone up. Nothing about a mythical robotaxi mockup changes this, and nothing in Musk's presentation appeared to hint about mass transit. He just wants to sell stuff.

Re: (Score:2)
Decompression on a airplane isn't generally fatal because it's not high enough to cause any problems other than oxygen. So use the supplemental oxygen and you're fine. Decompression of a hyperloop would be fatal to everyone, though thankfully it would be a quick death as you're just turned to paste by the shock wave.

The snag is that big ideas really can't be done by anyone except governments, or at least governments paying private industry lots of money. This is because private industry can't do it, you need a profit at every step of the way. Thus, defense contractors, government contractors, etc. Private industry that feeds on the teet of government. And they all want to milk that teet for all its worth. And if it can't be done for a small (in size) country like UK, then imagine it in America.
