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.

Absurdly expensive; the US is unwilling to foot that bill.

"near" is a relative term !

I reckon Fusion power plants will be up and running in the "near" term too. That is IMHO the only long term energy source, until we have warp engines, sub-space, and anti-matter/dilithium power.

But the pollution bill needs to be paid, IRstuff!

Fusion power plants will be up and running in the "near" term too, but not before 2040, rb1957.

In small to medium European countries hight velocity trains already replace with advantages the planes and are more ambiently friend.

But, there's a huge difference between paying up front a gigantic bill, vs. monthly installations. I could never have afforded buying a $300,000 house with cash, but $1,800/month is doable. Obviously, the difference is that the bill for pollution increases over time, even beyond inflation, but nevertheless, the concept still applies.

There have been several attempts to develop interstate bullet trains, but the cost has still be too prohibitive. One issue is that the US is not a particularly train-traveling country

from my knowledge USA was maybe the country which most contributed for the development of trains as a way of transportation.

At some point in history, perhaps; the Transcontinental Railroad was literally and figuratively groundbreaking, fresh out of the Civil War and needing to connect the East and West coasts.

Modern jets are running nearly 30 seat-miles per gallon of fuel. About the same as most people driving their cars to work at free-running highway speeds. Locomotives are more efficient at transporting cargo over long distances - Europe and Japan mostly use trucking. I'd rather the most efficient means be used for the largest amount of material than score railroad points with train fans.

 

[0707]

Trains don´t pollute and in therms of energy are maybe less expensive than jets I suppose!

Diesel is ostensibly a dirtier fuel than gasoline

trains, burning diesel, pollute …
oh, but he means his yet-to-be-invented "hyper" trains … they wouldn't run on anything as mundane as diesel !

and yes I've read about trains travelling in vacuum tubes … not in our lifetime.

I appreciate your optimism about fusion power ! by 2040 ITER will be up and running, and probably other demonstrators, but commercial fusion is unlikely in this century. But if we work on it now, we will get there.

I am speaking about trains moved by electricity not diesel trains! Electricity generated by wind power, hidraulic power,and sun power. Indirectly hydrogen power plants are already there but they still pollut with CO2. I have eard that England is already working in a fusion power plant to produce comercial clean hidrogen arround 2040.

I'll take any odds you want that it won't happen before 2050, or even 2099.

[0707]

Yes rb1957!Fusion power plants are still far way. But again high velocity electrical trains are less polluent than jet fuel planes don´t you agree? In Europe with the dimension of the cauntries if we achieve a place alf one hour later in a high velocity train than in a plane at the same or less price what does it matter? Meawhile the pollution is much less.

I missed it. What lab is running a continuous small scale fusion reactor that can be scaled up to a power plant? I can foresee that a clean energy source could capture CO2 from the air and combine it with hydrogen from split water to make a convenient hydrocarbon fuel that has high energy density and fits with current infrastructure. While we are hand-waving a distant future.

 

[rb1957]

Europe is smaller than the US (well, western Europe).

You've made trains non-polluting by relying on electrical power generated by renewables. This is not QED (Quite Easily Done). The infrastructure costs are "ginormous". The benefit small.

Why not replace intracontinental travel with the much more renewable horse drawn carriage ? Ok, we'd have to deal with the methane issue ...

3DDave in one of my anterior posts I said:"Indirectly hydrogen power plants are already there but they still pollut with CO2". I have nothing against planes but this pandemic times invite us to see how they pollut. My post is not against intercontinental planes. If you can demonstrate me that a big continental plane polutts less than a high velocity electrical train with the actual technology, I will surrend me.

Show me the transcontinental electrically driven high speed train for comparison.

CONTINENTAL FLIGHTS did you ear?
