@kapekape7580 Wow.. Instead of enlightening a genuinely ignorant person like me on the concept, you decided to be an asshole. I guess school never teach you courtesy .

Except for the membrane type, none of those designs seem to solve the harming marine life problem.

What the difference between attitude and altitude in this context?

@Taoquitok "mag lev vacuum train" to "wheeled cars in a normal tunnel" I think you're confusing the hyperloop with the Boring tunnel ( this is what you're describing here). The boring tunnel was never about "mag lev vacuum train" .

@DarktitanX2 "You do know electric car were created back in 1890" Yes, and it takes more than 100 years of development since 1890 for an EV to finally be able to compete and even outclass an an equivalent ICE vehicle. Technology doesn't stay stagnant, the same is true for the Hyperloop.

@DarktitanX2 Nothing about the hyperloop break the laws of physics. It may not ending up being competitive with existing transport tech or even economical, but the concept itself is physically and technologically possible.

@dhelsel89 The problem is lack of technology and the fact that vacuum "filled" container would be more disastrous/dangerous than hydrogen when there is a breach.
4
@DarktitanX2 The fact that they have succeeded (at varying stage) at this point proves that they are both physically and technologically (even with our level of tech possible ,. hence why you are still wrong in your OP.

@DarktitanX2 Good that you finally accepted/admitted that you're wrong.

@thornelderfin What is the frequency of replacement for those wall? If the rate is just a few years, than they might create more radioactive waste than current fission plants.

Any artificial meat need to pass a few hurdle: 1) is it a nutritious as real meat? 2) Is it cost competitive to real meat 3)Does it taste as good as real meat. Many fake meats fails these requirements.
2
@DarktitanX2 That not what you wee trying to insinuate in your OP. You were trying to claim that they were physically impossible when the fact is it is not the case.

@DarktitanX2 You should've said "Okay boomers" or what ever you kids these day says when an older gentleman tries to correct/educate you, boy. And you're welcome.

What vaporware are you talking about? Tesla Solar Roof is rea l product that have been used by consumers. And no, so far Space X isn't selling any ticket to Mars.
2
This battery need to competes with Li iron phosphate and sodium batteries in term of cost, safety and energy density.
2
@sethdrake7551 By that time material science/engineering would have evolved to the point that safe vacuum balloons and hydrogen (which I argue is already safe by today's standards ) would be the norm.
2
Space pollution? You're talking about potential Kessler syndrome scenario?
1
You didn't talk about lithium iron phosphate (LFP) batteries that is currently being used by the majority of Chinese automakers and even Tesla.

What is the power density of these batteries?

If they're burning the "coal" or biogass created by this process , then at best they're carbon neutral.

They can probably increase efficiency by replacing resistive heating with heat pumps considering they ahve over 100% efficiency (opposed to only 100% for resistive heating) : channel the excess solar generated electricity in the summer to heat pumps to extract the ambient heat in summer to be stored for autumn and winter months

@Taoquitok To be fair, Musk haven't really done anything with Hyperloop ever since he brought up the idea so he didn't really reneged on anything . Pretty much all developments for Hyperloop are being conducted by other unrelated companies and organisation while Musk seeming focussed on projects other than hyperloop (Tesla , Boring tunnel etc) . Surprisingly ,Musk himself didn't have a team on the project.

@solutionrebellion To be fair ,Thunderf00t isn't exactly a credible source for analysing hyperloop. To say that his methodology (misrepresenting the safety issues of hyperloop eg) he used in is some of his video are flawed (as well as the conclusion he tried to push by using them) is an understatement .
1
@Taoquitok That is pure speculation on your part. You could be right or you could be wrong (or somewhere in between), it's not something we can know.
1
@DBZHGWgamer There are multiple misrepresentation in Tghundrf00t's videos ( another user listed rebuttal to Thhunderf00ts videos in the comment section ). Once example of this is him misrepresenting the danger of sudden breach (no, a small hole would not resulted in a catastrophic explosive decompression), even going so far to rigging experiment with cherry picked variables to illustrate his point .He pushed the false conclusion that the hyperloop is more dangerous than it is because of this . Again, if you watch his video you would notice many of his problematic approach in his works such as contradictory statement (his videos gains batteries in EV eg), misrepresenting /cherry picking ( his anti Space X videos eg ) as well as completely missing the point in an otherwise slam duck topic ( EmDrive and Chernobyl miniseries eg).

@DBZHGWgamer ", he said a small hole would make maintaining a vacuum impossible, and he literally showed the math of the rate at which air enters a hole and showed that a total hole volume of like 5mm across multiple or a single hole would make maintaining a significant vacuum impossible" That assuming that such hole would be left unchecked and no one who monitor the hyperloop to even notice the sudden change in the air pressure within the loop. That is a rather unreasonable assumption to make but an necessary assumption needed to support the narrative of the loop being more dangerous than it really would be. "The only thing he ever implied would be "explosive" is the hyper loop imploding at the slightest structural failure assuming you actually managed to maintain any real vacuum in the first place. Which is not decompression, it's normal compression." You precisely repeated that misinformation he said: A) no model of the hyperloop were ever designed nor was going to have real vacuum in any way B) she amount of effort needed to cause such breach to happens On order for such catastrophic implosion to occur would require something very sudden , akin to a terrorist action such as using explosive (an d only explosive , even something like an anti material rifle would not produce such results) to detonate segment of the hyperloop . Even then he's assuming there were no safety measure designed to limit the extent of destruction

CORRECTION : Tesla S Plaid can't get from 0-60 miles/h in less than 2 seconds. The Engineering Explained youtube channel have a video titled "No, Tesla Can't Hit 60 MPH In Under 2 Seconds(Model S Plaid)" that debunks this claim from Tesla.

@TripleOmega In other word, it can only be done if one uses a house rule that only applies in drag racing and nowhere else in the universe/real life. Real engineering already delve on how absurd this definition is.

@TripleOmega I agree completely.

Pretty useless tech in the tropics.

Pardon me as I am not well versed in engineering: Wasn't another drawback of flywheels is that there is is a threshold of "reserve" energy in a flywheel that cannot be reextracted (unlike something likes battery that can be discharged to empty)? I heard this in an explanation about flywheel that I encountered around a couple of years ago. To be fair the presentation was very tech/engineering oriented and I suspect many thing did go over my head considering I'm knew very little of engineering and tech .

Wait, something called SWET being developed by a person named Epstein? I don't like the sound of this.

I think travel speed is the killing blow that make airship unfeasible for passenger fleets. I also think with the current technology , it would be safe to use hydrogen for crewed (or passenger) flights. Not only do they provides more lifts (thus leading to better efficiency and greater payload) , but can also be used for power in time of need when couple with fuel cells .
