Why the Hyperloop will Remain a Pipedream

Since Elon Musk released his designs for the Hyperloop transport system, the idea has been all over the internet as most people laud it for its ambition, and potential to truly change transportation around the world. Musk is so determined to make his idea work that he plans to entirely skip the concept phase and immediately build a 350 mile version of the Hyperloop to connect Los Angeles and San Francisco; basically his home to his office.

René Lavanchy, of the Guardian, does not share the enthusiasm for Musk’s designs, worried that there is no chance the Hyperloop will ever be built. “As far-sighted technology evangelism, the Hyperloop is laudable and deserves deeper discussion. As an intellectual idea, or the groundwork for some speculative fiction, it is fascinating. But as a shovel-ready infrastructure project, it is dead on arrival.”

In his article he offered several reasons why the Hyperloop would never work. He explained that in order to create the air cushion that the pods would float on, the air would have to be compressed rapidly, which would create huge amounts of heat inside the pod and the tube. The tight conditions within the Hyperloop do not allow for air conditioning, which means that that the whole systems could suffer from overheating, just like the London Underground, making travel unbearable for passengers.

Elon Musk has estimated that the cost of the Hyperloop will be tiny, however that seems very unlikely when considering the fact that the main method of reducing costs in giant manufacturing projects is through mass production of identical pieces. However with the Hyperloop track, due to the necessity to keep the pipe completely horizontal, the support pylons must all be built to different height specifications, making mass production unfeasible.

Lavanchy also noted that whilst Musk has stated that his Hyperloop can be built above the central reservation of the Interstate Highway 5 in order to remove the need for purchasing new land. In theory this works, however, such construction would require the closure of the road, which is fine in urban environments, where cars can be diverted around the closed road fairly easily, but closing the I-5 for several years would be impossible.


The largest stumbling block for the Hyperloop project that Lavanchy spoke of will be the securing of finance. The problem is that infrastructure investors are adverse to risk, and creating a brand new transport technology is considered very risky. The problem is that if the technology fails in anyway, the resulting accident could be catastrophic. For this reason it is unlikely that the project will receive any public or private equity fund money.

    The whole idea of publishing this an an 'open source' proposal was to get folk thinking about the practicalities of implementing it, like the sensible suggestions by David.

    But isn't it sadly predictable that a newsletter for the oil industry would try to poke holes in a solar-powered project?

    The passenger cabin will be a pressurised container, the same as any commercial aircraft, and of course will be air conditioned in a similar manner.

    The proposal uses water and a heat exchanger to trap the heat generated from air compression in steam, which is swapped out at journey end. Simple.

    The support pylons could be mass-produced in various heights, in 1m intervals, and precise levelling could then be done by excavation of the pylon footing. Simple.

    The I-5 would only be required to be reduced by a single lane for a short distance to allow access to the pylon sites, and this could move up the I-5 as it is built. Once up, the first tubes could be used as railroad platform for further tubes, carrying them to a tube-riding crane, which installs them. Again only requiring closure of a single lane at the end point. Simple.

    All of these objections are solvable with a little thought and intelligent design, however it is easier just to criticise.
