Hyperloop is a conceptual transportation system proposed by Elon Musk in 2013. It relies on air bearings and residual air pressure in low-pressure tubes for lift and propulsion — distinct from full-vacuum vactrains. Though the Alpha design was released open source, and test pods achieved speeds of 463 km/h (Technical University of Munich, 2019) and 172 km/h with passengers (Virgin Hyperloop, 2020), no commercial deployment exists. Hyperloop One ceased operations on 31 December 2023. A European draft standard appeared in 2023, but no regulatory or financial pathway to operation has materialised.
It began as an open-source white paper — not a prototype, not a company, not a regulation.

Mechanism
It uses air, not vacuum, for lift and thrust — a deliberate departure from vactrain logic.

Proof Points
The fastest run was 463 km/h; the only human trial hit 172 km/h — both on short, straight, purpose-built tracks.

Collapse
Hyperloop One shut down on 31 December 2023 — the most funded player, gone.

What it is and the problem it solves
A proposed high-speed transportation system first published by Elon Musk in a 2013 white paper. It aims to move capsules at aircraft speeds through low-pressure tubes — solving regional travel time but not cost, safety certification, or network integration.
How it works
Capsules ride on air bearings inside low-pressure tubes. Linear electric motors provide acceleration. Residual air pressure in the tube supplies lift and propulsion — unlike vactrains, which require near-vacuum and separate propulsion systems.
What works
Air-bearing levitation works in controlled environments. Linear motor acceleration works. A Technical University of Munich pod reached 463 km/h in July 2019. Virgin Hyperloop carried humans at 172 km/h in November 2020.
What does not
It does not move people or freight commercially. It does not operate outside test tracks. It does not solve last-mile access, energy cost per passenger-kilometre, or land-use conflict for above-ground tubes. It does not scale beyond isolated demonstrations.
What it changes
Nothing yet. It has not altered transport policy, infrastructure planning, or public investment priorities outside speculative proposals. Its open-source Alpha design has not yielded operational systems.
Is it worth your time
No. Hyperloop One ceased operations on 31 December 2023. No commercial system exists. No regulatory framework is in place beyond a draft European standard. The technology remains unproven at scale.
