In kaj ti to pomaga, da so cenejši, če pripeljejo primerljivo manj "tovora". Seveda so mogoče cenejši za izdelavo, vendar dražji za izdelavo in vzdževanje na količino prevoza.

Razmišljaš preveč ozkogledno. Če vsa prevozna sredstva prilagodiš manjšemu predoru (manjša in hitrejša), ni nujno, da prepeljejo manj tovora.

A je res treba razlagati?

Tiste kupujejo ljudje, ki jih načelom znajo uporabljati, in jih ne uporabljajo za zabavo. Tole pa kar kliče po nesreči.

Kaj pa moraš znati uporabljati? Načeloma vsak normalen odrasel človek ve, kako približno je treba rokovati z ognjem.

Elon: So, what I discovered is that there are massive improvements possible in tunnelling technology. I always look at things from a 'fundamentals of physics standpoint'; if you apply physics first-principles to any given endeavour you can sort of envelope the possibilities. And what I discovered from talking tothe engineerings heads of the tunnelling companies was that they actually did not know, had no idea what the true potential of tunneling was. Because the first question I'd ask was, "Is the tunneling machine power limited or thermally limited?" And not one of them could answer the question. And I was like, "Well, this is not a good sign." And the answer is, everything is power limited within the framework of how much you can transfer heat away from the face with some sort of liquid cooling system. But we're so far away from that, crazy far away from that, of being anywhere near the thermal limit. Things like increasing power is relatively easy, but then you get to the point where you're melting the drill head. So, you have to put a lot of effort into cooling the drill head so you don't melt it, or go with advanced ceramics, and you still have to cool the bearings and the bearing housings, so... I'm used to a lot of the stuff from rocket engine design; the turbopump in the Merlin engine goes 36k RPM, it's got 10k horsepower, in ways...

Kara: So applying rocket technology to what you're doing with tunnels.

Elon: Essentially taking rocket technology and automotive technology and applying it to drilling technology.

Kara: Right. So the problem is it's too hot.

Elon: No. We need to massively crank up the power to the drillhead, then we need to cool it. But the first step is jacking up the power like crazy and then automating the placement of the tunnel reinforcements.

Kara: So that you don't have to continue going slowly to build it.

Elon: Right now tunneling machines will drill for a bit, and then they'll stop, and people will very slowly put in the reinforcements. So tunneling machines basically go at about half speed.

Kara: I think of that a lot about house construction. Why is house construction so slow?

Elon: Well, you can make house construction crazy fast if you're in a factory. Construction in general is... I think there's a lot of potential for disruption, and for entrepreneurs to enter construction in general... I think there's a tremendous amount of opportunity. Anyway, massively cranking up the power of the drill. And second, making it battery powered. If you don't make it battery powered, you have to have this massive cable. And then the cable, in order to be manageable at all, has to be like an 11kVa, 11 thousand volt cable, and even then it's thick. And then you've got to have step-down transformers for the drill head, because the drill head is going to operate at like 480 volts or thereabouts... so you've got these massive transformers, this crazy cable length...

Kara: So slow.

Elon: So it's very slow. And this is what blew my mind, they're using a diesel locomotive. The standard practice is to use a diesel locomotive to transport the tunneling segments to the drillhead and transport the dirt back out. And one way.

Kara: Like an old coal mine.

Elon: Yeah, it's so weird. So if you have a diesel locomotive in a tunnel then you've got to put this massive effort into blowing clean air into the tunnel and getting...

Kara: So how else would you get the dirt out?

Elon: We just use an electric car. So we took a Model 3 chassis and converted that into a train. Model 3 powertrain...

Kara: So you don't need to worry about the rest of the stuff.

Elon: It's not consuming oxygen and spewing noxious fumes. This was a big improvement.

Kje smo kaj popušili? Musku se bo recimo še kolcalo zaradi vseh teh njegovih obljub o samodejni vožnji. Lako čemo, samo što nije, drugo leto pa zares ... Slej ko prej bo postalo jasno, da prodaja meglo.

Da prodaja meglo, se bo že kmalu izkazalo tudi pri kopanju predorov. Zelo vprašljivi so sončni strešniki - se je že pred dvema letoma hvalil z njimi, zdaj pa priznava, da jih še preizkušajo. Načrt za Mars tudi že popravlja - zdaj za 2024 ni več sigurno, da bodo šli astronavti tja, ampak samo raketa.

Megalomane pač čaka streznitev - slej ko prej.

Drugače pa, Muskovemu kopanju predorov smo se smejali že takoj, ko jih je prvič omenil. Nič novega.

Kaj si ti ustvaril v zadnjih 10 letih ko Musk ni ustvaril nicesar?

Kaj točno želiš povedat? Da nihče, ki je v zadnjih 10 letih naredil manj kot Musk ne sme kritizirat Muka?

Slej ko prej bo postalo jasno, da prodaja meglo.

Inženirji rudarstva se ob tem Muskovem modrovanju nedvomno samo smejejo

Pred tremi leti je Musk obljubljal super-duper robotizirano tovarno, v kateri bodo trojke delali hitreje in ceneje kot to zmorejo "dinozavri". Izkazalo se je, da je bila to iluzija, in da avtov ne znajo delati hitreje in ceneje od tekmecev.

In potem ima Tesla še balast v obliki SolarCityja, za katerega je vse bolj jasno to, kar so nekateri govorili že od vsega začetka - da je izgubar, ki ga ni mogoče rešiti.

Elon makes them all look like the fools they are [Madison Av; Wall St.; money the only value they can see]
- build rockets that land, 3-D printed rocket motor nozzles.
- builds one of the largest Manufacturing plants on Earth [OK, only 1/3 so far] slight embellishment for now]
- quickest, safest sedan ever built? Model S near 50% market share of Luxury Sedan market most everywhere
- quickest, safest SUV Model X
- top selling Mid-Luxury sedan in about 1 1/2 years of production. out sells BMW, Mercedes, Audi ... Jag, Lexis, Acura
- 500 vehicles per year to +250,000 in a decade
- solar/glass roofing system
- battery storage for both residential and utility/industrial scale.

Why such bad press?
-Madison Ave. not getting their cut - no Ads
-Tesla pays back loans (bad precedence for other corporations)
- R&D 2010-2917 < .3 billion total - exposes at best waste, at worst theft at other corporations.
- Boring company $10 million/mile so far - LA subway add-on about $10 billion/mile - savings? for sure.
-real competition and great products: safest, quickest, cheapest to operate, long lasting, decreasing prices
-Wall Street - volatility not truth is their game - look to Michael Lewis for one to explain Wall St.
-US press in general has become click bait ad sales - truth has long since disappeared
-education been privatized so only for profits now - wisdom (use of facts/problem solving) been lost along with concepts of truth- leads to poor journalist and poor readers.
(California spends more on prison system than University of California System.)

side note: and the trolls all call for Elon to "hire" some expert auto executive to do better. what nonsense.

Komaj čakam da vidim končni izdelek projekta Dugout Loop. Komaj čakam 10 Decembra da vidim kaj je pripravil Elon Musk. Ideja je res zanimiva sicer sem skeptičen glede električnih avtomobilov vendar pa si bom tole pogledal z zanimanjem. Je kdo seznanjen s tem projektom? Kakšna so vaša mnenja glede projekta???

Ne pozabi, da vse skupaj financira Elon sam

Kitajci trenutno gradijo tako imenovane hitre železnice z bullet train-i in na tem področju praktično dominirajo ZDA iz vseh strani.

Očitno Elon Musk razmišlja že korak naprej

Resnično upam, da tisti projekt, ki so ga nekaj tednov nazaj potrdili v Los Angelesu (hitra železnica... 77 milijard dolarjev vreden projekt) opustijo in da se posvetijo temu kar počne Musk.

... public transport is painful. It sucks. Why do you want to get on something with a lot of other people, that doesn't leave where you want it to leave, doesn't start where you want it to start, doesn't end where you want it to end? ... [using public transit meant rubbing shoulders with] like a bunch of random strangers, one of who might be a serial killer. . . that's why people like individualized transport, that goes where you want, when you want.

In cities, elonmusk's hatred of sharing space with strangers is a luxury (or pathology) that only the rich can afford. Letting him design cities is the essence of elite projection.
