Not sure about this video in particular, but I remember thunderfoot being pretty thorough and accurate in the past.

#13The Dubai hyperloop project is supposedly proceeding. The 10km test track was supposed to open this year. Can't find any info later than January 2020.
The Dubai to Abu Dhabi link is the ideal case. The route is mostly flat, open desert. Funding is available. There is government support. There's considerable traffic between those points. If that doesn't work, not much else will.

#14Read it as Pipes of Fantasy. Years ago I remember reading about miles long test tracks being built. I haven't been following developments surrounding this at all, but as far as I can tell there are still no serious test tracks, why? The ones that are out there are supposedly too short to get to full speed (or anywhere close to it!). Given the hype surrounding it I have a hard time believing money is the limiting fact…
Elon seems to have moved on to non-vaccuum underground tunnels via The Boring Company, which is actually doing real projects.
Though apparently there are still Hyperloop competitions planned. The 2020 one was supposed to be "in a 10km vacuum tunnel with a curve", though that may be stalled by, well, obvious current events.

No one else seems to have quite the combination of money and crazy to go much further with Hyperloop.

Regular slow rail and siphoning tax dollars? Sounds like an Elon company.

He is awfully repetitive and his earlier videos on the subject are more informative, but he's basically right. If the basic science disagrees, it must be a scam until proven otherwise. Plenty of studies were done on the accuracy of labs done on finger sticks before Theranos, but investors were not paying attention.

#18This is evergreen when talking about Hyperloop: http://www.cat-bus.com/2017/12/gadgetbahn/ The problems with building this have nothing to do with technology but with right-of-way, investment, and politics. If those factors were solved, we'd already have high-speed rail in places where Hyperloop has been proposed. The fact that we don't says that Hyperloop is unlikely to be feasible as well.
Which is why the first Hyperloop will probably be built outside the USA.
Melbourne to Sydney always seemed like a good choice to me. It's one of the busiest air routes in the world[1], there is obviously tons of solar, lots of open land beside the existing road, no seismic activity to speak of and it's a good long distance to get up to speed (~1000km).

Agreed.

No time or planning should go into surface hyperloops. These things belong underground. 100x better.

Not really, there’s a fourth factor not listed here, which is government vs. private. A government project will, for political reasons, need to support universal access, and a public transit system will have a hard time telling a person “you smell too bad to get on the bus.” A private company won’t have any such problems and can build only for the rich and middle class. The problem that Hyperloop solves is creating 1/20th the throughput at 1/20th the cost, which brings the project feasibility into the private sector domain and allows a product to be sold to the richest and/or cheapest-to-serve 1/20th of the market.
