In 2013, PayPal mafia don and head of Tesla and SpaceX Elon Musk bought caught up within the libertarian opposition to California’s overdue, over-budget and under-delivering high-speed rail undertaking.
He known as it “the slowest bullet practice on this planet and the costliest bullet practice per mile on this planet”. (It was neither, however he wasn’t that far improper.)
Musk proposed a futuristic different. Now, each time a tech whiz child with no transport engineering background “invents” a brand new public transit system on paper, it’s sensible to deal with it with wholesome scepticism – and one eye on ulterior motives.
However let’s begin in the beginning.
Authorised by referendum in 2008, California’s bullet practice was alleged to hyperlink San Francisco and Los Angeles with a two hour, 40 minute practice journey at as much as 350km/h, a visit that conventionally takes six hours by automotive or an hour and 20 minutes (plus airport switch and ready instances) by air.
Success would have an apparent impression on the gross sales of different modes of transport, similar to the electrical automobiles that have been changing into fashionable on the west coast on the time, and which, by a loopy coincidence, Tesla bought.
Musk’s intuition in regards to the practice was proper, to be honest. Nearly 20 years later, the undertaking is a large number. Its “preliminary working phase” is predicted to start out operating in 2032, and solely stretches from Bakersfield to Merced, every of which is a few third of the way in which from the cities at both finish.

Up to now, it seems to be like a bullet practice from nowhere to nowhere.
The principle cause for this mess is that it’s exceedingly troublesome to make the required property purchases or expropriations, particularly within the city and suburban areas of high-priced cities. The nearer you get to both Frisco or LA, the more severe it will get.
If establishing a route wasn’t troublesome sufficient, California’s politics and regulatory pink tape drive up the prices of any megaproject, and that’s earlier than you’ve budgeted for the inevitable lawsuits.
This makes California’s high-speed rail undertaking a number of instances costlier and slower to construct than an equivalent undertaking could be within the boondocks, or underneath an authoritarian regime that may simply minimize by way of pink tape.
This conundrum required, Musk thought, a few of his trademark out-of-the-box pondering. He was after a mode of transport that – in comparison with automobiles, trains or aeroplanes – was “safer, sooner, decrease price, extra handy, proof against climate, sustainably self-powering, immune to earthquakes and never disruptive to these alongside the route”.
That’s fairly the want listing.
“Is there actually a brand new mode of transport – a fifth mode after planes, trains, automobiles and boats – that meets these standards and is sensible to implement?” Musk mused in a white paper printed on Tesla’s weblog on 22 August 2013, entitled “Hyperloop Alpha”.
That’s fairly the ambition.
Mach 0.99
Within the paper, he describes a system of metallic tubes from which a lot of the air has been evacuated, inside which capsules whizz suspended on air cushions.
These passenger capsules could be accelerated to a staggering 1 220km/h (or Mach 0.99) by linear electrical motors, sustaining their velocity by the use of front-mounted air consumption followers that negate air resistance and likewise present pressurised air for the suspension. The large followers make them look just a little just like the sandworms from Dune.
The tubes could be raised on 25 000 pillars to minimise ground-level obstructions.
Every capsule would carry 28 passengers, and departing as typically as as soon as each 30 seconds throughout peak hours, giving it the flexibility to hold all current commuter site visitors between the 2 cities.
The entire thing would price US$6-billion for a passenger-only system, or $7.5-billion for a bigger, extra versatile model, which works out to lower than 10% of the price of the high-speed rail system California is presently constructing. Musk estimated tickets would price $20.
Saying that he didn’t have time to really pursue the undertaking, he open-sourced it to let different firms have a go at implementing it.
The whizbang renders, together with the megaphone of Musk’s identify, attracted a bevy of start-ups, together with Hyperloop Transportation Applied sciences, Virgin Hyperloop One and TransPod.
Universities launched analysis initiatives and had graduate college students construct prototypes and check tracks.
The engineering challenges, nonetheless, proved way more extreme than the early optimism urged. The unique Musk design bumped into bother nearly instantly. His proposed air cushion levitation system was discovered to require an outrageous quantity of vitality to compress air, making the system much less fuel-efficient than air journey. The ensuing air hole was additionally too skinny for real-world circumstances, the place even millimetre-scale misalignments from shifting earth or strange put on may trigger deadly accidents.
A whole bunch of thousands and thousands of {dollars} of investor funding was sunk into these firms and analysis initiatives.
Many variations have been made, similar to discovering lighter and stronger supplies to assemble the conveyor tubes, and changing air cushion levitation with electromagnetic levitation (learn: The practice that by no means got here – how maglev expertise was derailed).
But none of those firms ever produced a working prototype that bought even near the efficiency and effectivity required to make the Hyperloop possible, at the same time as a subsidised public works undertaking.
Inside 10 years, just about all of them have been defunct (though a couple of stragglers and college analysis programmes have but to get the memo).
The technical challenges have been just too nice. Because it seems, centuries’ price of tried-and-tested engineering expertise wasn’t simply old style and unimaginative. It represented the mixed information of generations of engineers about what was each virtually possible and economically viable.
Everybody ought to have seen this coming.
If it was possible to depressurise tunnels which might be tons of of kilometres lengthy to 0.1% of atmospheric stress, why has no high-speed railway system ever proposed doing so? The discount in air stress alone, if all else stays equal, would absolutely make trains way more gas environment friendly?
If air cushion levitation, which Musk likened to that of an air hockey desk, was a viable technique of decreasing friction in such a depressurised tunnel, why has that by no means been used on regular high-speed trains at atmospheric stress, which may gulp in far denser air to create such a cushion?
If photo voltaic panels, which Musk needed to mount atop the tubes to energy all the system, can energy Hyperloop capsules to the velocity of sound, why haven’t railways constructed photo voltaic panels above their tracks to energy their completely strange trains?
The ultimate blow
If the conveyor tubes are to be nearly completely depressurised, how will the system deal with department traces and a number of stations?
What occurs in an accident that pierces the pores and skin of the capsule? Does everybody simply suffocate?
How will metallic tubes tons of of kilometres lengthy cope with thermal enlargement and seismic motion, whereas retaining hermetic seals?
These objections are apparent, even to this ageing tech journalist with no engineering background in any respect, and analysis engineers weren’t capable of clear up any of them.

The economics have been the ultimate blow. Researchers on the Technical College of Delft, which specialises in novel types of transit, discovered that Hyperloop fares must exceed €0.30 per passenger-kilometre for profitability, in comparison with solely €0.174 for high-speed rail. Musk’s unique declare of $20 tickets for journeys between Los Angeles and San Francisco proved wildly unrealistic. Transportation economists labored out {that a} cheap return on infrastructure funding would require fares in extra of $1 000.

That might make automobiles, trains, planes, ships, bikes, bicycles, rickshaws and donkey carts superior types of transport to the Hyperloop.
One of the best query, nonetheless, is that this: if the Hyperloop have been such an excellent thought, then why hadn’t anybody considered it earlier than? Is Elon Musk uniquely sensible and modern?
In his paper, Musk nodded briefly at prior artwork, together with patents by Robert Goddard, filed for in 1945 and granted in 1950, and subsequent proposals by the Rand Company and ET3.
“Sadly, none of those has panned out,” wrote Musk. He speculated briefly and superficially about some attainable explanation why they haven’t panned out, earlier than shifting on to his personal spin on these concepts.
What Musk omitted in his paper is the truth that the thought goes again a lot additional than Goddard’s 1950 patent.
The usage of pneumatics to energy a railway goes again to the early 19th century, greater than 200 years in the past. In 1810, George Medhurst, an engineer residing in London, printed a pamphlet entitled “A New Methodology of Conveying Letters and Items with Nice Certainty and Rapidity by Air”.
Two years later, he expanded the diameter of the tube proposed in his first pamphlet, and printed “Calculations and Remarks Tending to Show the Practicability, Results, and Benefits of a Plan for the Speedy Conveyance of Items and Passengers upon an Iron Highway by way of a Tube of 30 Ft in Space, by the Energy and Velocity of Air”.
This title not being sufficiently explanatory, he printed one other tract within the 12 months of his loss of life, 1827: “A New System of Inland Conveyance, for Items and Passengers, Able to Being Prolonged all through the Nation, and of Conveying all Sorts of Items, Cattle, and Passengers with the Velocity of Sixty Miles in an Hour, at an Expense that won’t Exceed the One-fourth A part of the Current Mode of Travelling, with out the Assist of Horses or Any Animal Energy”.

It fell to at least one John Vallance to construct the primary sensible prototype, nonetheless. Motivated, like Musk, by the obvious price, sluggishness and inefficiency of typical railways, he constructed a mannequin of a system that labored by suctioning a carriage by way of a pipe by pumping out the air forward of it.
Numerous 19th-century engineers, amongst them the redoubtable Isambard Kingdom Brunel, developed variations on the thought, referred to as “atmospheric railways”.
To keep away from the necessity to pump out huge volumes of air, most newer variants linked carriages to a piston that ran inside a pipe embedded within the monitor between the rails.

The good benefit of those methods was that the engine driving the system may stay stationary, as a substitute of losing great quantities of vitality conveying heavy locomotives alongside the monitor.
Maybe most colourfully, an early subway pioneer by the identify of Alfred Ely Seaside shocked New York’s public and politicians by unveiling, in 1870, a totally accomplished and luxuriously appointed pneumatic subway practice that ran for 95 metres instantly beneath Broadway.
Due to political rivalry with William M Tweed, the boss of Tammany Corridor, who had corrupt transit plans of his personal, Seaside, a prolific inventor with many patents to his identify, was denied the correct to assemble a subway.
His resolution was to take action in secret, at night time, and so current New York society with a fait accompli.
The Seaside Pneumatic Railway labored, albeit at a stately 10 miles an hour – far lower than the 60mph Seaside had initially promised. Nonetheless, it was extraordinarily fashionable with the curious and thrill-seeking inhabitants of New York.
Quickly, competing payments – one for Tweed’s proposal, and one for that of Seaside – landed on the desk of the governor, John T Hoffman. Figuring out the place his political bread was buttered, Hoffman instantly signed Tweed’s invoice and vetoed that of Seaside.
The pneumatic practice ran up and down its quick monitor for a 12 months, however was then closed, buried and forgotten, till subway building employees rediscovered it in 1912.
For over 200 years, inventors have had just about the identical concept that Elon Musk had. For over 200 years, ingenious engineers have tried to make the thought work. For over 200 years, they’ve failed.
The failure of the Hyperloop is however the latest of quite a few prior makes an attempt. But it nonetheless has all the elemental shortcomings that it has at all times had.
It sucked up huge quantities of personal and public capital all over the world, diverting sources from extra promising public transit initiatives – together with typical high-speed rail.
However then, maybe that’s what Musk supposed all alongside. This whole lark price Musk the time it took to write down a rushed white paper. He most likely outsourced a lot of it to his military of overworked flunkeys at Tesla and SpaceX.
By making it open supply, he seems to be like he’s doing humanity a favour.

Any distraction from, and extra friction for, a high-speed rail undertaking that would cut back Tesla’s electrical automobile gross sales, at completely no price to himself, should absolutely be chalked up as a fantastic success for Elon Musk. – © 2026 NewsCentral Media
