achieves superconductivity by using liquid nitrogen instead of liquid helium
Regardless of our opinion(s) of China, just take a look at that. These motherfuckers are building cities and high-quality transport systems, the US capitol was raided by a man dressed as a fucking minotaur with nordic runes as tattoos.
China is talking about what their economic plan for 2035 is going to be, the US is still discussing wether COVID is real or not.
Damn, long term economic planning huh? Sounds nice. Wish it was me.
no don't you see we should instead let the most important facet of our society up to sheer chance and the whims of rich assholes
But have you considered the benefits of trains that hold 4 people and reach 100mph on a short test track?
500 mph land speed? That easily twice over what even the fastest trains have achieved in the past. Is it really safe to run a land vehicle at that speeds? Surely there must be some negative side effect to running that fast?
Not dunking on the project though this is cool as fuck
So a 500 mph railroad would be for long haul, cross continental trips like the Trans Siberian railway and not what you take getting to work every day?
Have you been in a city with a subway? The speed on the tracks is not the issue. They're fast enough already. The main thing slowing you down is the many stops, it only takes like a couple minutes to get from one stop to the next. So there isn't really a point to faster urban trains. High speed trains are for long distances.
Have you been in a city with a subway?
no because I am am*rican :angery:
Subways are awesome. I have a car but I prefer not to use it because it is just so much more convenient to use the subway instead. This last year I have to use the car though because of covid :(
But yeah every big city with the capacity to have a subway should have one, it brings everything close, combined with a good bus and tram system. Many people in the suburbs only use their car to get to the nearest subway station. Here you typically only have to wait like 5 minutes for the subway to show up, tickets are around 1.30 euros (and it's not that hard to avoid them altogether), and they go fast af. I wish we had a couple more lines though. One is under construction but it's gonna be years before it's over because everything takes way too damn long in this country. But hey, at least we have subways.
Yeah that's approaching the sound barrier. Idk what affect that would have on the surrounding area of the train for QOL. Tbh this seems like generic really early reporting of one paper that may or may not go anywhere.
You can just run this thing slow (aka normal HSR speed) in urban areas and only let it go full blast once its out in rural areas.
Since this type of train requires laying new track, you can plan the route so that it impacts as few people as possible.
Love that clip in the video of a person just taking a ruler and waving it back and forth under the train to show that it was levitating at a complete standstill, super cool! :pog-dolphin: 🚄 :lenin-pogger:
Show that to the average Chinese person loving 100 years ago and they'd assume it was done by magic. Insane how far a country can advance in that time.
I fucking love maglev, it's what kid me thought the future would be
My knowledge of materials science is scant at best, but isn't LH quite a bit colder than LN? I just remember running equipment at my college we used LN to keep LH cold.
Besides an absolute pain to store and work with, helium is also usually gathered as a byproduct of natural gas which is not a resource China possesses in particular abundance.
Basically, China is choosing to work with the most Proletariat of the Nobel gasses.
Chad Nitrogen: 78% of the atmosphere.
Virgin Helium: Floats off into space.
If you use REBCO magnets you don't need the Cold of LH so LN is good, and also LN is way cheaper and renewable
