A decade ago, Elon Musk proposed a new form of transport that would shoot passengers through vacuum tunnels in levitating pods at almost the speed of sound — he called it “hyperloop”.
Since then, cities from Abu Dhabi to Zurich have been touted as destinations, research projects have gobbled up millions of dollars and a host of commercial ventures have sprung up — even Richard Branson got involved.
“The transportation network has not had a new mode for over 100 years,” said Rick Geddes, a transport infrastructure expert at Cornell University in the United States, who compared the excitement to the early days of aviation.
But nobody has come close to making the hyperloop work.
The difficulties have ranged from costs and finding suitable locations, to simply persuading people that travelling through a narrow tunnel at speeds faster than a jet plane is a good idea.
Musk’s initial proposal would have been a “barf ride”, transport blogger Alon Levy wrote at the time.
Despite all the problems, though, the hyperloop idea still energises university campuses, corporate board rooms and city halls across the world.
Hidde de Bos, a 22-year-old engineering student, first heard of it four years ago.
His university at Delft in the Netherlands excelled in competitions run by Musk’s SpaceX firm, which invited students to develop pods to fire through vacuum tunnels.
“It made me really excited to see what the possibilities were,” he said.
He is now chief engineer of Delft Hyperloop, a non-profit university spin-off.
De Bos said the SpaceX competitions, which were discontinued in 2019, were too focused on speed and became like “drag races in a tunnel”.
Now, his team is taking part in a student-led competition, European Hyperloop Week, which he hopes will refocus on sustainable energy and developing levitation systems.
And Musk himself recently gave a jolt to the hyperloop fraternity by tweeting that his tunnelling firm The Boring Company would “attempt to build a working Hyperloop” in the coming years.
Musk first mentioned the idea in a 2012 media interview before publishing a white paper about it a year later.
But his direct involvement has been sporadic, and he has always encouraged others to develop the idea.
Los Angeles-based firm Hyperloop TT, among the first and most enthusiastic firms to run with Musk’s idea, welcomed his return.
Rob Miller, the firm’s chief marketing officer, told AFP it was “further validation” for the concept.
But he stressed that hyperloop was now much bigger than just one man.
Bearing out his point, new proposals have emerged in recent months from local authorities ranging from Italy to India.
However, proposals are one thing, and revolutionising public transport is quite another.
In its early years, Hyperloop TT signed exploratory deals in India, China and beyond.
In 2019, the firm promised a 10-kilometre (six-mile) track would open in the UAE the following year.
None of these projects has come to fruition.
