@Tsaukpaetra Ye gods, 40 minutes!
;tl;dw?

@boomzilla Serious engineer talking about a big project requires non-trivial amount of time to explain it. News at 11!

@masonwheeler So...nothing interesting in the video?

@boomzilla I wouldn't know. I'm at work and haven't watched it yet.

Elon Musk blowing more smoke up his fanboys asses.
Elon Musk's plans for travel in underground tunnels condemned
Costa Samaras, a professor at Carnegie Mellon University in Pittsburgh, has criticised plans that would see electric 'skates' transporting cars at high speed in narrow tunnel under cities.
-
@Polygeekery Meh. Some college professor says "it'll never work."
A lot more people than him have gone broke betting against Elon Musk's ideas...

Ah...so:
@masonwheeler said in Getting hyper loop vibes...:

Was actually correct in his usual way about Musk. In this case:
Costa Samaras, a professor at Carnegie Mellon University in Pittsburgh, has decades of experience in tunnel construction.
-
@masonwheeler said in Getting hyper loop vibes...:
Meh. Some college professor says "it'll never work."
A lot more people than him have gone broke betting against Elon Musk's ideas...'We're just going to figure out what it takes to improve tunnelling speed by, I think, somewhere between 500 and 1,000 percent,' he said during a Hyperloop design competition at SpaceX.
If it were just that easy, it would have already been done. But at least this project will be at atmospheric pressure.

That's just the thing. It's not easy. Which is why it takes some real talent to accomplish it. (See also: SpaceX, improving greatly on literal rocket science.)

Now you're getting it!!
@masonwheeler said in Getting hyper loop vibes...:

Oh, you lost it. Nevermind.
It is not about just throwing talent at the problem. Tunnel boring jobs are slow and expensive for a host of reasons. The majority of that is the simple fact that as your bore gets longer, so does the logistics. And they are limited by the diameter of your bore. That is a hard limitation and not something that you can handwave away.
I say this as a person who was involved in one TBM project, and probably a hundred jack-and-bore projects.

No.

Like electric cars not being practical, or rockets not being resuable?
These problems don't get "handwaved away"; they get solved by smart people putting a lot of R&D into them.
No.
...no what?

@Tsaukpaetra said in Getting hyper loop vibes...:
so i watched the whole video waiting for him to get to the point where he explains how he's going to make the next evolution in vibrators and he never did.
Thanks Elon Musk for getting my hopes up. I wanted you to make toys that could take me to space, and instead all you did was bore me for fourty minutes.
1/5, would not watch again.

alas, no. it wasn't the fun kind either. it was the very very very tediously boring kind.

@Perverted_Vixen Yeah, forty minutes is a long time. Most uncomfortable.

@Polygeekery What is the point of driving a fast car down a tunnel unless you can hear it?
-
@masonwheeler said in Getting hyper loop vibes...:
Like electric cars not being practical,
When did electric cars become practical?
-
@masonwheeler The energy density of hydrocarbon fuels is much higher than batteries. (The car I am driving does 400 miles a tank and that is because I have a lead foot).
My car can do almost 700 miles on one tank. The best electric car might do 1/4 to 1/3 of that.
EDITED: My grammar is awful as always.
-
@masonwheeler said in Getting hyper loop vibes...:

They still aren't, for anything more than around town commuting. FFS man, some of the first cars were electric. But electric cars are not practical for 400 mile trips. Or driving your family on vacation.
@masonwheeler said in Getting hyper loop vibes...:
or rockets not being resuable
I am unimpressed with their landing a rocket on a barge. This is something that has always been possible, but it was not done because of the tradeoff in payload capacity. You have to take up enough fuel with you to burn for the landing. All of that fuel is weight that you are not taking in to orbit.
But, they are apparently saving money doing it. So kudos to them. But this has been something that has been possible all along.

What have they improved greatly?

You're a Neanderthal.
And so am I: nothing like the sound of a well-tuned V8/V10/V12 echoing off the tunnel walls :D

@lucas1 said in Getting hyper loop vibes...:
@Polygeekery What is the point of driving a fast car down a tunnel unless you can hear it?
The cars don't even drive in the tunnel, they get transported by moving platforms on tracks. At that point, why even have the car at all? Just stand on the moving platform, or put chairs on it or whatever.
-
@RaceProUK Man once I was feeling a bit weak after being ill for about 4 months (I had a infection in my gut) I got pissed off. Went down to the Spanish butchers and told them to give me the best steak I could eat. I literally flash fried a steak an inch and a half thick and drank the blood off the plate. Immediately afterwards I felt like I could apply to be part of the Avengers.
-
@hungrier Well, the idea is that after you get to a central* drop off point, you can drive to your actual location.
* because it is REALLY hard to add adequate drop off points after a city has already been built

Or how about long cylindrical compartments, where people could sit and relax during the trip, and possibly watch a homeless man masturbate with glee?
Shit, we just invented subways.

A few minutes before one's tee time.

@hungrier I think Elon Musk doesn't understand why people like driving.

It's surprising how often people forget this fact. Even the guys who convert to E85 get to enjoy losing a third of their fuel economy.

They're certainly quite good for whipping up the Tesla Racing Channel idiot fanboys into a frenzy. These types, who know nothing about drag racing and obsess over 0-60 times (when 0-60 is a silly metric to begin with) are possibly more toxic to the auto enthusiast community than ricers.

I'll do it if I have to (which I do)... but I don't like it.

As of 4 months ago, the best electric car had a range of 335 miles. (Which is plenty practical for @Polygeekery's 400-mile trip.) And there's some new battery technology under development to replace lithium technology with glass, of all things. It promises to have about twice the energy density, and not contain the highly flammable components that make lithium batteries so dangerous.
When this is market-ready, that 335-mile Tesla will have a range of around 670 miles, easily competitive with your 700-mile car.
-
@RaceProUK Thanks. I run one of those Dirty Diesels and no unless I buy a fast car I am keeping it. £50 for 600 miles when I am smash it on the motorway.

You don't math good.
-

Well, whether that's practical or not depends on how quickly it charges - What's the charge time on Teslas? If it's reasonable to charge it within, for example, a meal time, that would work. But if it takes 3 hours to charge, that gets pretty impractical...
-
@masonwheeler The range they quote is a top end estimate. That is driving at 55mph on a perfectly flat road with no wind against you etc etc.
Take 30% off of that and you are getting close to the right number.
-
@masonwheeler said in Getting hyper loop vibes...:

How long will it take to charge? My vehicle only has a range of about 300 miles, but I can refuel it in a few minutes. Electric cars take many hours to fully charge.

-
To make an electric car that works for road trips it needs to get 300-400 miles per charge and have a recharge time of <1hr. (that allows for a 1hr break every ~6hrs which most road trips will allow for) Oh, it also needs to be able to do this without a complicated infrastructure change. (so not some special recharging station that won't exist in 99% of the US).
-
@sloosecannon I can fill up my tank in about 60 seconds at Tesco. Probably takes 4 or 5 minutes in total and half of that is waiting for the card machine to read and verify my pin.
