New high-temperature super-conductor

Then why did you mention it?

And not include Airbus?

Sounds like a coverup.

Airbus would probably do a great deal better if they could re-locate the company someplace outside of the EU. As things stand at present, all businesses are severely hampered by the EU's complex anti-business legislation, which runs into millions of pages; thousands upon thousands of impenetrable chunks of prolix verbiage (all resulting from the EU's continual need to show the member states it's actually doing *something* to justify its existence- even if that "something" has crippling economic consequences for everyone).

I noted a new order for 737s. I didn't mention an air show.

But if orders at the air show are just PR, why bother mentioning it?

And why exclude Airbus?

The British Airways order was announced at the air show, after Airbus had run away with the market:

Your posts are highly misleading.

Because the geology of the Earth is not a flat table, and we have things like rivers to cross, etc. etc.

There are reasons it would not be a straight run.

Having it that way would be nice. A plotted line averaged to lay straight through the state best positioned such that the city-to- line-depot transitions are as short as possible. Sounds like a mess.

Better to have the links between the cities as straight lines with transitions at the city nodes to best point the line toward the next stop.

Yes... there would be stops. Not much sense to have a train that runs the length of the state and only be able to board it at the endpoints.

To go between more than two cities? Seems like they're needed at Albuquerque.

Musk likes the idea. It must be good.

I don't think you'll see many small-scale uses for HTSs until they find one that's useful at LN2 temperatures. As mentioned here already, "useful" includes current density.

What? Did you miss the "underground" part? It won't be 10 feet undergroun d, it would be 100's of feet underground, well below surface obstacles.

Such as???

What? The subway in DC is built with very few turns. The ones they have a re purely to get the tracks in the right alignment for the station. That s ubway is only a few feet underground mostly. I think parts of it are more like running under the Potomac.

I thought this was about transcontinental travel? The stuff you normally n eed a plane for.

There is no subway in DC. The submerged lines you refer to are Trains, and they aren't subway trains. They trail into and out of the city from other cities. ALL of DC's local transit is ground based BUS lines. Contrast Boston or NYC or any city with real subways and note they have turns. So do the DC trains, BTW.

Oh and wait, what you refer to is the TRAIN line DC has. I rode it in to DC from Great Falls a number of times. A half hour ride from Va over to the Capital, and come up to see the Washington Monument in one direction and the Smithsonian in the other. They have other lines from other cities.

A long haul, city to city jaunt line like that referred to in the thread would have nodes at those cities and the entire line may well have vector alterations at each node, since at each node, the train must stop anyway. Not much between nodes, but it does happen.

It does not matter how deeply it is buried. The shallower the better from a servicability POV. Much less in the event an emergency egress is required.

California wants to make a long haul fast train.

Intercontinental, and particularly transoceanic would be virtually impossible.

Better off building a space elevator with a variable lift and release point. Sky dive back to your destination.

Yup, You're not in this for the hunting

For a large scale (>50 %) deployment of unreliable renewable sources such as solar or wind, you either need

1.) Storage capacity for a day (solar) or a week (wind) consumption 2.) An energy transfer network, since unreliable sources are available at different places at different times. An east-west power line around the planet with power insertion and extraction at the continents would be nice. A cable between Japan and Portugal would also be quite helpful, especially with solar panels in Japan pointing eastward and westward in Portugal. Current high voltage AC lines are economical to about 1000 km transfer, DC links to a few thousand kilometers. HTS would be required for truly continent wide networks.

Sure there is a lot of regulation in the EU, but it is not really anti-business, in fact EU was based on getting more trade between countries. Sure politics makes idio^H^H^H^Hstrange decisions, but that is the case everywhere, they outlawed pulse fishing (fishing using electric shocks) while the Netherlands had invested a lot in it as it really works and saves the environment(tm) and saves fuel and costs. As to Airbus, they have factories in China and other countries:

Have you ever seen this old movie? :)

Airbus doesn't seem to be remotely crippled. Boeing just had the 737-MAX disaster, which does suggest that the more-business-friendly environment in the US is sub-optimal in stopping corner-cutting managers from killing passengers.

We do know where Cursitor doom gets his opinions from, and they aren't exactly independent sources - he sucks up right-wing propaganda and does seem to beleive it.

Underground tunnels go under rivers. They don't cross them.

The Channel Tunnel is a particularly obvious example.

Airlines work by having feeder routes into major centres, and longer distance links between those centres.

Railways work with non-stopping express trains between major centres and slower stopping trains to distributes the passengers to and from their homes to the major centres.

I knew you would come back with the technical definition.

Lame. A city subway train is NOT what DC operates.

Oh and that definition is lame too. There are subways in cities throughout the world.

What the f*ck are you mumbling about now, boy?

Yup, nothing but pure, RETARDED MUMBLING. Grow the f*ck up.

And, the success of the quicksort algorithm suggests that the scheme of short-long-longer hops is a generally applicable principle. This has also been implemented in containerized cargo haulage, big ships for long trips, rail for medium, tractor/trailer trucking for short hops.

It all works well, until some virus scrambles all your routing notes.
