I agree. I think I'd hate myself if I had a personality that was so closed off to the possibility of things being possible.

As the saying goes.

If Henry Ford had asked his customers, they would have told him they wanted a faster horse.

People always use the Henry Ford angle to suggest he was bringing some entirely un-practical solution to the table. He wasn't. The genius of H.FORD has nothing to do with automotive technology advances (the modelT was nothing special in that respect) and EVERYTHING to do with the realisation that Mass Production brings cost viability to otherwise un-tenable technology.

Ford made the production line a reality, which in tern made the Mode lT viable, and NOT the otherway around!!!

it would work if you could manage the acceleration/decceleration

Any technical issues will be overcome eventually. Whether it will be cost effective as it stands is another question, I would choose this over flying domestically any day though.
I wouldn't - if the "vacuum" system fails then you're dead, and putting something like that out in the open in a county filled with people with guns is asking for it.
Like the Elevator/Lift it will, of course, have fail safes built in should a catastrophic failure occur.

Henry was beaten to the production line by several other people, not least Brunel senior who equipped Portsmouth Royal Dockyard's block mills with machinery for the mass production of pulley blocks.

If someone can stop a 600km length of steel from expanding 300m between hot and cold days, yeah, it will be great:

LOL. Expansion gaps?

Makes you wonder how railway track (which is welded) works over the east coast mainline?

It wasn't my point, it was the video creator's point. If you watch the video you might get his point.

I'd be more worries about building it in a known earthquake area. What's the prognosis for someone doing 900 kph in a force 3 quake?

No-one has ever tried to create fluid-tight pipes 100km+ long ever, no siree, and they've never managed to solve any of the associated engineering problems. rolleyes

So how do they transport oil, gas, water, steam etc then? In buckets?

There's a 2,300 mile long oil pipeline in Canada that doesn't appear to leak.

I don't know for sure, but I'd guess that oil, water and steam have heat management systems by the very nature of transporting oil, water and steam. Almost like car engines (and other things that generate heat) are cooled by water or oil.

Again, as per the video: none of those fluid pipes have ever tried to transport people, and they haven't meant death in the case of a single point of failure. They haven't even risked the entire contained product in the event of a single point failure; if there is a leak they can close a valve to stop the flow and repair the damage. You can't just close a valve on a 15 tonne, 900kph capsule containing people. As an aside, how fast are those fluids transported?

Even if there is a non-fatal problem and the loop is shut down, how do you get people out in an emergency?

Seriously, watch the video, he lays it out a lot better than I can.
