what is this guy's counter-argument? he has a lot of incredulity, but based on what? and meanwhile the hyperloop had its first successful passenger test despite this guy's incredulity...
Plus he HAS been making tons of videos talking about this hyperloop. Did you ever play around with the vacuum bells in highschool? Why do you think they are made so damn thick and curved in a bell shape? Along with the massive seal you have to have. What you are essentially doing is making a reverse submarine tube that you ride in, for hundreds of miles. It is not financially feasible.

This has been discussed on here various times before.
1. it is unnecessary
2. it is dangerous in case of an incident
3. it is outrageously expensive (even compared to a very expensive maglev train)
4. it is ridiculously difficult to construct (even compared to a maglev train) just think about vacuum sealing expansion joints every mile or so, probably less.
I could go on, even for an engineer like myself not an interesting concept.

faulty assumption. vacuum ≠ perfect vacuum. while it does require a lot of energy to create a perfect or near perfect vacuum, the mild vacuum like the 100Pa they use in the current hyperloop tests requires very little energy input and are not dangerous. 100Pa pressure is about the same as a strong breeze. a pressure of 120Pa is the same as the pressure a quarter exerts on whatever it is lying flat on, for comparison.

hyperloop is proposed to run at 100 Pa (1 mBar) that is one thousandth of ambient pressure, close enough to a "perfect" vacuum to create the exact same problems.
In other words the pressure difference to the environment is 999 mBar (0,999 Bar) or 99.900 Pa.
Your comparison to a breeze is inherently flawed as the pressure difference is NOT 100 Pa.
In the video above of the imploding tanker above towards the end one guy says "Siebenhundertsechzig" (760) I would assume this is the the pressure difference (i.e. the amount that needs to be deducted from ambient pressure to derive the actual pressure inside the tank) at the time the tank collapsed, probably the unit is mBar, maybe (doubtful) it was the remaining tank pressure in Pa.
Assuming it is mBar, that would mean that the remain pressure in the tank was 240 mBar or 24.000 Pa.

(sounds retarded)
Did you even watch the video? Did you really???
