Hyperloop i USA ska skicka kapslar i 1000 km i timmen

Elon Musk var den första att mynta begreppet ”hyperloop”, ett transportsystem där kapslar dras och bromsas in med hjälp av magnetkraft.

Ett av bolagen som vill göra verklighet av idén är Virgin Hyperloop One, som driver en testanläggning nära Las Vegas i USA.

– Kapslarna kommer att kunna färdas upp till 1 000 kilometer i timmen och till en lägre kostnad än att flyga, säger Jay Walder, chef på Virgin Hyperloop One, till The Economist.

Could dawdling America lead the world in a new form of transport?

Some urban planners in the Midwest think so.

The Economist, August 8th 2020 edition

For decades not much has changed in how Americans shift themselves and their goods about. They mostly still rely on cars, lorries, trains and planes that would look familiar to someone visiting from the mid-20th century. Now, various companies are pushing for the regulation of (and public support for) schemes to create public intercity transport within depressurised pipes. A mention of the method, in a House infrastructure bill passed last month, has spurred excitement that these pipe-dreams could become reality.

“You could move between Columbus and Chicago in 40 minutes”

Jay Walder, Virgin Hyperloop One

A hyperloop system involves passengers or freight transported by pods elevated by magnets, which travel within raised pipes. The pods can be propelled at 620mph (1,000kph), says Jay Walder, boss of Virgin Hyperloop One, one of the firms pushing the idea. At that pace “you could move between Columbus and Chicago in 40 minutes”, he says, so covering the 460 miles many hours quicker than by driving and at a cost (and overall carbon impact) that he says would be lower than flying.

His firm runs an experimental centre near Las Vegas, where engineers—including some who worked on the Mars Rover programme—have run over 400 tests using a 500-metre-long pipe. So far they have sent pods flying at 240mph, though slowing down can be tricky. “We’ve shown it can work,” he says. He hopes next to build a 15km pipe to test the higher speeds, possibly near Columbus, Ohio, though Missouri and parts of some western states are also interested. Requirements include flat topography, empty space and no corners.

These schemes are sufficiently advanced for some state and local-government officials to take them seriously. Thea Ewing, of Ohio’s transport commission, says a recent feasibility study showed it could be done. The population is booming in Columbus, which lost all its rail services in 1979, so there is plenty of demand for new transport—for example, to Chicago and Pittsburgh. She says the pipes could come up on state-owned land beside motorways or (where they exist) railways. Another route being considered would link Kansas City and St Louis, both in Missouri.

Why do it? “We see it as something to help convert the region,” she says. Looking ahead to projects that would not be completed until mid-century is common practice for transport planners. A hyperloop could allow spouses to work in different cities while still living together, or Ohioans to pop to Chicago’s fancy restaurants or concert venues for an evening.

In reality, though, such schemes would only be viable if they were useful for transporting goods, too. “Mostly this would be for freight,” says Mark Patton, who oversees transport plans for the Columbus region. Paul Judge, who runs a thriving plastics manufacturer, Axium, in the city, says he would welcome it if it meant he could run a big factory, cheaply, in one spot and ship his billions of units of shampoo bottles, hand-sanitisers and the like to markets in the region.

Who would pay for it? Both private and public funds would be needed. Some public help would come from providing the land, but investors hope for more. Mr Walder says he expects America will eventually see a $2trn national infrastructure plan to help restart the economy. Part of that might throw the Midwest a loop.

bakgrund
 
Hyperloop
Wikipedia (en)
A Hyperloop is a proposed mode of passenger and freight transportation, first used to describe an open-source vactrain design released by a joint team from Tesla and SpaceX. Hyperloop is a sealed tube or system of tubes with low air pressure through which a pod may travel substantially free of air resistance or friction. The Hyperloop could convey people or objects at airline or hypersonic speeds while being very energy efficient. This would drastically reduce travel times versus trains as well as planes over distances of under approximately 1,500 kilometres (930 miles).Elon Musk first publicly mentioned the Hyperloop in 2012. His initial concept incorporated reduced-pressure tubes in which pressurized capsules ride on air bearings driven by linear induction motors and axial compressors.The Hyperloop Alpha concept was first published in August 2013, proposing and examining a route running from the Los Angeles region to the San Francisco Bay Area, roughly following the Interstate 5 corridor. The Hyperloop Genesis paper conceived of a hyperloop system that would propel passengers along the 350-mile (560 km) route at a speed of 760 mph (1,200 km/h), allowing for a travel time of 35 minutes, which is considerably faster than current rail or air travel times. Preliminary cost estimates for this LA–SF suggested route were included in the white paper—US$6 billion for a passenger-only version, and US$7.5 billion for a somewhat larger-diameter version transporting passengers and vehicles. (Transportation analysts had doubts that the system could be constructed on that budget. Some analysts claimed that the Hyperloop would be several billion dollars overbudget, taking into consideration construction, development, and operation costs.)The Hyperloop concept has been explicitly "open-sourced" by Musk and SpaceX, and others have been encouraged to take the ideas and further develop them. To that end, a few companies have been formed, and several interdisciplinary student-led teams are working to advance the technology. SpaceX built an approximately 1-mile-long (1.6 km) subscale track for its pod design competition at its headquarters in Hawthorne, California.Currently, aside from Sea-Tac airport IAF link in Greater Seattle, India is officially pursuing the hyperloop technology for Pune-Mumbai corridor.
