Continental flights in the very near futur will be replaced by High Velocity trains 3

[0707]

Because of pollution, Continental flights in the very near futur will be replaced by High Velocity trains, because trains are much less polluent and will compete more and more in velocity with planes. Intercontinental flight planes will keep going on making sense but, they have to change to a less poluent combustible maybe hydrogen will be well positioned.

And according to my drs. Fusion has been achieved in my spine and my foot for some time already.

Fusion is easy; but does your fusion have net positive energy production without something blowing up, that's the question.

yes, sure … but at what cost (to create a magnetic levitation track) ?

another day in paradise, or is paradise one day closer ?

 

[0707]

how doest it costs an A380?

luis

 

[rb1957]

much less than a maglev track !

another day in paradise, or is paradise one day closer ?

 

[0707]

An A380 costs about 446 M dollars

You can compare it with the costly MAGLEV infrastructure costs in the site below

yep, one track, 200 miles long, is expected (estimates always go up) $55 billion.

Chinese maglev track costs $40million per km.

Above a certain speed, trains don't make much sense, since their fuel efficient will go to pot.

"Advantages of Maglevs

The foremost advantage of maglev trains is the fact that it doesn’t have moving parts as conventional trains do, and therefore, the wear and tear of parts is minimal, and that reduces the maintenance cost by a significant extent.

More importantly, there is no physical contact between the train and track, so there is no rolling resistance. While electromagnetic drag and air friction do exist, that doesn’t hinder their ability to clock a speed in excess of 200 mph.

Absence of wheels also comes as a boon, as you don’t have to deal with deafening noise that is likely to come with them.

Maglevs also boast of being environment friendly, as they don’t resort to internal combustion engines.

These trains are weather proof, which means rain, snow, or severe cold don’t really hamper their performance.

Experts are of the opinion that these trains are a lot safe than their conventional counterparts as they are equipped with state-of-the-art safety systems, which can keep things in control even when the train is cruising at a high speed.

Disadvantages of Maglevs

While the advantages of Maglev Train System may seem quite promising in themselves, they are not enough to overshadow the biggest problem with the maglev trains: the high cost incurred on the initial setup. While the fast conventional trains that have been introduced of late, work fine on tracks which were meant for slow trains, maglev trains require an all new set up right from the scratch. As the present railway infrastructure is of no use for maglevs, it will either have to be replaced with the Maglev System or an entirely new set up will have to be created―both of which will cost a decent amount in terms of initial investment. Even though inexpensive as compared to EDS, it is still expensive compared to other modes.

If the advantages and disadvantages of these trains are pitted against each other, it can be a bit difficult to come to a concrete conclusion. While the high cost of initial set up is something that a developed nation like the United States won’t have to worry about, the fact that the entire infrastructure has to be replaced with a new one will be something that will have the experts in a catch-22 situation. But obviously, we will have to do away with their disadvantages if we are to invest in maglev trains. If the commercial success of the Shanghai maglev train is to be taken into consideration, these trains can be surely considered the transport system of the future."

There are some experts who report that because of the decarbonization of the planet the trips of airplane flights up to 600Km will be banned. This reinforces the increment of high velocity electric trains up to 1000 or 1500Km distances.

there are some experts who report the world is flat … but anything can happen and trying to guess what will be flavour of the month a month from now is IMHO fruitless.

rb1957 do not deny at first, a science that you do not know, ostriches hide their heads in the sand, this is dangerous for their survival, be careful.

I might want to see some empirical data to support any of the claims related to availability and costs of any of the technologies discussed here, before I believe that any of this is more than conjecture, fantasy, or maybe just cognitive dissonance. I keep seeing "There are some experts..." I'm pretty sure "There are some OTHER experts..."

It's all okay as long as it's okay.

I heard in Portugal a very credible guy say that flights up to 600 to 1000Km will be banned in the short time due to the need for descarbonization. As in EUROPE and other continents the most of the travels are of 600 to 1000km dimention, if this flights were banned they represents lots of carbon emission reduction. In that case electric high velocity trains start being atractive because they pollut much less and 1 or 1,5 hours in time waste makes no sense compared with a flight burocracy turning a travel diference time between a high velocity train and a plane almost the same.

Bullet train is profitable in Japan and probably China, because they aren't obsessed with driving, as in the case of the US. The US has never been that enamored with trains, after the development of the automobile. People on the east coast might be more amenable to train travel, particularly those who normally ride the subway to/from work.

Politicians in Europe might be dumb enough to ban such flights, but no chance it happens in US.
