Pa pola milijarde i nije neka cifra za nesto tako inovativno. Jos ako ispadne od toga nesto drugo, puna saka brade. 

 

Nije ako moze da funkcionise, hyperloop ne moze da funkcionise i da bi mogao treba utrositi znatno vise para, a onda se ne dobija zeljeni cilj - brzi i jeftini transport. 

 

Evo ovde ima zasto ne moze da fukncionise

Hvala na informacijama, nisam imao pojma o tome da li je Musk vlasnik hyperloop-a i da li je vlasnik neke od kompanija kojie se bave tom tehnologijom - znam jedino da se nista oko hyperloop-a ne bi desilo da Musk nije pogurao mastu investitora i inzenjera i pokrenuo ih na akciju. 

 

Zli jezici kazu (na osnovu price sa prijateljem Muska) da je Musku vrlo smetala ideja brze pruge LA-SF jer bi po njemu to uticalo na prodaju tesli mladim itejvcima kojima je bitno da brzo putuju a da ne zagadjuju sto bi omogucila brza elektricna vuca. 

 

Elem njegov cuveni white paper je uticao da se bilo kakvi radovi po pitanju brze pruge odloze dok se ne vidi da li hyperloop je stvarno tako dobar kako Musk kaze.

 

Inace sama ideja je mnogo starija, Musk je samo promenio oslanjanje umesto magneta ili hidraulike vazdusni jastuk u sistemu u kome se sve vrti oko vakuma, pa ne cudi sto je Hyperloop One je batalio Muskovo resenje vazdusnog jastuka ili ti prosto ko air hockey sto Musk rece, jer ne funkcionise, ubacili maglev i prakticno su napravili ono sto je deda americkog raketnog programa Robert Goddard predlagao 1930tih a patentirao 1945:

 

 

Ovo je deo patenta u kome Godard pominje i maglev (u prvom tekstu koji je napisao se radilo o maglev resenju) ali posto tada nisi imao industrijske superprovodnike maglev je bio nemoguc tj smatrao se tehnologijom buducnosti pa je u patentu predlozio hidraulicnu "levitaciju" kao realnije resenje.

 

Musk je predlagao vazduh jer je samo to drugacije od drugih vakumskih vozova da eto moze da kaze ja smislio... sto vazdusni jastuk ne radi nebitno.

 

Godard je je inace pravi pravcati inzenjer pa jos raketni, Musk nije iako iz petnih zila pokusava da nas ubedi da jeste.

Uopste ne ulazim u njegove motive, samo odajem priznanje da sve sto radi uspije da pokrene i ljude i pare - moguce pogresne ljude i  tudje pare i sa potpuno drugacijim ciljevima nego sto je javno proklamovano ali stvari se jednostavno pocnu dogadjati kada ih on pogura, promovise ili kako god zelis. 

 

Nisam vidio da drugi celnici najvecih kompanija imaju slican uticaj i doseg. Mislim da ni Bezos, ni Gates, ni Zuckerberg pogotovo ne Buffet, Waltoni i Arnault ne mogu uraditi nista slicno... Na kraju krajeva, i na ovom forumu jedino on ima svoju temu...

Da su zeleli takav uticaj negde i nekad bi bar pokusali.

 

Ne znam da li ste primetili ali sto si veca dileja i ekscentrik imas veceg uticaja na masu. Cak ni kada ih ispalis po ko zna koliko puta, sledbenici ne odustaju tako lako.

Ko su ljudi koji rade u SpaceX? Da li su oni prethodno radili u drzavnim agencijama? Da li su oni bolji od ostalih, privoljeni novcem za rad, ili slican kvalitet inzenjera mozemo videti i u drzavnim agencijama, ali je celokupni menadzment ono sto ove kompanije cini brzim jacim boljim?

Ono što te kompanije čini "boljima" je u prvom redu sam Ilon. Zapravo reč "bolje" je understatment, to nisu firme koje su malo bolje, malo efikasnije, koje imaju mali edž u odnosu na konkurenciju, pa da bi se tu mogla identifikovati neka partikularna heuristika o tome kako firmu učiniti efikasnijom (mada i toga naravno ima na pretek) - to su firme koje rade stvari koje su pre nego što su ih napravile smatrane pozitivno nemogućim! NEMOGUĆE je smanjiti troškove lansiranja 10 PUTA. NEMOGUĆE je proizvesti komercijalno električko vozilo u Americi. NEMOGUĆE je napraviti satelitski internet, NEMOGUĆE je napraviti komercijalni brain-computer interface itd, isl - to su sve bila opšteprihvaćena "znanja" svakog "respektabilnog" čoveka, Ilonu su se svi rugali zbog ovih stvari, "beži mali, ne zamajavaj nas", dok odjednom više nije bilo tako smešno...Tačniji opis od toga da su bolje je da te firme nemaju konkurenciju. Ako Đokovic osvaja sve turnire bez izgubljenog seta, a istovremeno kao najbolji igrač osvaja svetsko prvenstvo u fudbalu gde Srbija sve dobije 5:0, a istovremeno je najbolji pijanista na svetu i dobija nobelovu nagradu iz fizike i Oskara za najbolji film koji je režirao - well, do njega je.

 

Ovakva kombinacija - koju zatičemo kod Ilona - ekstremne inteligencije, fokusiranosti, znanja i osećaja za fiziku i inženjerstvo, energičnosti, upornosti, osećaja za rizik i trejdofove u različitim kontekstima (od inženjerstva do biznisa), te vrhunskih epistemoloških kriterijuma i sposobnosti da se odmah prodre do suštine (inženjerske, ljudske, finansijske, menadžerske, logističke ili bilo koje druge) problemske situacije, itd - je nešto što nikada do sada nije zabeleženo u ljudskoj istoriji. Nema druge osobe na svetu koja zna sve o raketama i o logističkim problemima Aleksandra Makedonskog ili različitih vojski u WWII, koja razume trejdof između optimizacije proizvoda i efikasnosti proizvodnje, koja precizno prepoznaje i spremna je da prihvati šansu za uspeh od 10% ako je return veći od 10X, koja tako dobro procenjuje ljude (Ilon lično intervjuiše čak i čistačice) i alocira svoje i tuđe vreme (cut the bullshit), itd - i koja radi preko 100 sati nedeljno!

 

Mislim da u korenu njegove filozofije leži nešto što Dejvid Dojč zove "princip optimizma" - duboka istina da je moguće sve što nije eksplicitno zabranjeno zakonima fizike, samo uz dovoljno znanja/rada. Odatle dolazi njegovo prepoznavanje da nešto MOŽE bez obzira što svi tvrde suprotno. U tom smislu, na primer, on ima koncept "Idiot index" koji meri razliku između cene ulaznih komponenti i cene završnog proizvoda. Visok Idiot index znači da NEGDE stvari mogu puno da se poprave, uz pravo znanje. Rakete su bile tipičan primera visokog Idiot indexa, dok ih El Grande nije uzeo pod svoje...

Nekoliko odlomaka iz Maskovih biografija, ove (koja postoji i u srpskom prevodu), ove nove i ove knjige o ove knjige o ranim danima SpaceX-a:

Spoiler

SpaceX needed an actuator that would trigger the gimbal action used to steer the upper stage of Falcon 1. Davis had never built a piece of hardware before in his life and naturally went out to find some suppliers who could make an electromechanical actuator for him. He got a quote back for $120,000. “Elon laughed,” Davis said. “He said, 'That part is no more complicated than a garage door opener. Your budget is five thousand dollars. Go make it work.’” Davis spent nine months building the actuator. At the end of the process, he toiled for three hours writing an e-mail to Musk covering the pros and cons of the device. The e-mail went into gory detail about how Davis had designed the part, why he had made various choices, and what its cost would be. As he pressed send, Davis felt anxiety surge through his body knowing that he’d given his all for almost a year to do something an engineer at another aerospace company would not even attempt. Musk rewarded all of this toil and angst with one of his standard responses. He wrote back, “Ok.”

 

The actuator Davis designed ended up costing $3,900 and flew with Falcon 1 into space.

 

------------------------------------------------------------

Musk had to sign off on every expenditure over $10,000. “It was his money that we were spending, and he was keeping an eye on it, as he damn well should,” Watson said. “He made sure nothing stupid was happening.” Decisions were made quickly during weekly meetings, and the entire company bought into them. “It was amazing how fast people would adapt to what came out of those meetings,” Watson said. “The entire ship could turn ninety degrees instantly. Lockheed Martin could never do anything like that.” Watson continued:

 

 

Elon is brilliant. He’s involved in just about everything. He understands everything. If he asks you a question, you learn very quickly not to go give him a gut reaction. He wants answers that get down to the fundamental laws of physics. One thing he understands really well is the physics of the rockets. He understands that like nobody else. The stuff I have seen him do in his head is crazy. He can get in discussions about flying a satellite and whether we can make the right orbit and deliver Dragon at the same time and solve all these equations in real time. It’s amazing to watch the amount of knowledge he has accumulated over the years. I don’t want to be the person who ever has to compete with Elon. You might as well leave the business and find something else fun to do. He will outmaneuver you, outthink you, and out-execute you.

 

--------------------

Veliki Robert Zubrin:

When I met Elon it was apparent to me that although he had a scientific mind and he understood scientific principles, he did not know anything about rockets. Nothing. That was in 2001. By 2007 he knew everything about rockets - he really knew everything, in detail. You have to put some serious study in to know as much about rockets as he knows now. This doesn't come just from hanging out with people.

 

----------------------------

When an engineer came to Musk’s cubicle and told him that the air-cooling system for the payload bay of the Falcon 9 would cost more than $3 million, he shouted over to Gwynne Shotwell in her adjacent cubicle to ask what an air-conditioning system for a house cost. About $6,000, she said. So the SpaceX team bought some commercial air-conditioning units and modified their pumps so they could work atop the rocket.

 

---------------------------

 

Musk initially relied on textbooks to form the bulk of his rocketry, knowledge. But as SpaceX hired one brilliant person after another, Musk realized he could tap into their stores of knowledge. He would trap an engineer in the SpaceX factory and set to work grilling him about a type of valve or specialized material. “I thought at first that he was challenging me to see if I knew my stuff,” said Kevin Brogan, one of the early engineers. “Then I realized he was trying to learn things. He would quiz you until he learned ninety percent of what you know.”

 

People who have spent significant time with Musk will attest to his abilities to absorb incredible quantities of information with near-flawless recall. It’s one of his most impressive and intimidating skills and seems to work just as well in the present day as it did when he was a child vacuuming books into his brain. After a couple of years running SpaceX, Musk had turned into an aerospace expert on a level that few technology CEOs ever approach in their respective fields.

 

-----------------------------------------------------

The absolute worst thing that someone can do is inform Musk that what he’s asking is impossible. An employee could be telling Musk that there’s no way to get the cost on something like that actuator down to where he wants it or that there is simply not enough time to build a part by Musk’s deadline. “Elon will say, fine. You’re off the project, and I am now the CEO of the project. I will do your job and be CEO of two companies at the same time. I will deliver it,”’ Brogan said. “What’s crazy is that Elon actually does it. Every time he’s fired someone and taken their job, he’s delivered on whatever the project was.”

 

------------------------------------------------------

Garrett Reisman:

What's really remarkable to me is the breadth of his knowledge. I mean I've met a lot of super super smart people but they're usually super super smart on one thing and he's able to have conversations with our top engineers about the software, and the most arcane aspects of that and then he'll turn to our manufacturing engineers and have discussions about some really esoteric welding process for some crazy alloy and he'll just go back and forth and his ability to do that across the different technologies that go into rockets cars and everything else he does...

 

------------------------------------------

It was an example of Musk’s policy that the designers sketching the shape of the car should work hand in glove with the engineers who were determining how the car would be built. “At other places I worked,” von Holzhausen says, “there was this throw-it-over-the-fence mentality, where a designer would have an idea and then send it to an engineer, who sat in a different building or in a different country.” Musk put the engineers and designers in the same room. “The vision was that we would create designers who thought like engineers and engineers who thought like designers,” von Holzhausen says.

 

------------------------------------------

His focus on cost, as well as his natural controlling instincts, led him to want to manufacture as many components as possible in-house, rather than buy them from suppliers, which was then the standard practice in the rocket and car industries. At one point SpaceX needed a valve, Mueller recalls, and the supplier said it would cost $250,000. Musk declared that insane and told Mueller they should make it themselves. They were able to do so in months at a fraction of the cost. Another supplier quoted a price of $120,000 for an actuator that would swivel the nozzle of the upper-stage engines. Musk declared it was not more complicated than a garage door opener, and he told one of his engineers to make it for $5,000. Jeremy Hollman, one of the young engineers working for Mueller, discovered that a valve that was used to mix liquids in a car wash system could be modified to work with rocket fuel.

 

After a supplier delivered some aluminum domes that go on top of the fuel tanks, it jacked up the price for the next batch. “It was like a painter who paints half your house for one price, then wants three times that for the rest,” says Mark Juncosa, who became Musk’s closest colleague at SpaceX. “That didn’t make Elon too enthusiastic.” Musk referred to it as “going Russian” on him, as the rocket hucksters in Moscow had done. “Let’s go do this ourselves,” he told Juncosa. So a new part of the assembly facility was added to build domes. After a few years, SpaceX was making in-house 70 percent of the components of its rockets.

Koliko čujem Ajzaksonova knjiga bi trebalo takođe da se pojavi i u srpskom izdanju...

 

 

btw, pošto je to bilo prvo pitanje, inženjeri u SpaceX dolaze uglavnom iz drugih privatnih kompanija, ne nužno čak ni raketaških, nekima je to i prvi posao, svi uče na poslu itd, tu nema neke prevelike mistike...

Ekstremno inteligentni free speech absolutist je uspeo da jos jednom smanji vrednost svoje igracke. Od prvobitnih 44, X procenjen od strane Fidelity-a na 12,5 milijardi. Haha

Nikada nije vredio 44. Ne vredi ni tih 12. Vredela je kao propagandni alat dok je mogao da brani jednima da pricaju a druge stiti. Sada kada ne moze, vredi kao i svaki drugi messenger.

Vidim izbrisao si da Elon intervijuse i cistacice 🙂

 

Licno poznajem troje koje rade/radili za Teslu. Jedan je neki CNC manufaturing manager (jedan od glavnih za programiranje in house manufacturing-a, covek je najbistriji programer kojeg sam upoznao u zivotu). Drugi je robot programer/automation programer kod energy division a treci (skoro familija) radio (inzenjer) na baterijama za model S. Ni jedan nije imao interviju sa Ilonom, mozdas rekli zdravo ako su se sreli, cak vise neki upste i nece da imaju puno posla sa njim.

 

Medjutim stoji da je covek genije za inovaciju, proizvodnju i project managment. Moj biznis partner i ja se jos uvek cudimo kako su brzo sagradili Kinesku fabriku, za manje od godinu dana. Mi ponekad ne mozemo da dizajniramo i napravimo neki spravu koja je 10 miliona puta jesnostavinje od toga za 3-4 meseca.

Da se vratimo na inovacije i ulaganja. Jedna kompanija kompanija za koje smo radili prototipe skoro 4 godina, a poceli su 2012-te, jos ni dan danas nemaju nista na trzistu (a nikad nece ni imati, u pitanuu je neki heat-exchanger). Za to vreme je Ilon vec poslao ni ne znam koliko raketa u svemir.

Vidim izbrisao si da Elon intervijuse i cistacice 🙂

Nisam izbrisao ništa, to je jedna od stvari koje sam zapamtio čitajući nekoliko njegovih biografija i knjiga o pojediničanim biznisima. Citat, recimo, odavde:

 

He interviewed almost every one of SpaceX’s first one thousand hires, including the janitors and technicians, and has continued to interview the engineers as the company’s workforce swelled.

 

 

------------------------------------------------------------------------------------

Ali drugo nešto. Prema juče objavljenim podacima u Evropi je prošle godine prvi put najprodavanije vozilo bilo električno. Model Y - sa rastom prodaje većim od 100%:

 

U SAD, kada su u pitanju električni automobili podaci o prodaji stoje ovako:

 

1. Tesla Model Y (385,900 units sold, estimated)

2. Tesla Model 3 (232,700 units sold, estimated)

3. Chevrolet Bolt EV/Bolt EUV (62,045 units sold)

4. Rivian R1T/R1S (47,200 units sold, estimated)

...

 

Ovo je dovelo do toga da vrednost Teslinog stoka (TSLA) u 2023. poraste za više od 100%!

 

Što se tiče statistike uspešnih lansiranja u 2023. - bilo ih je 211, od čega SpaceX 96, što je naravno apsolutni godišnji rekord! 45%! Čestrdesetpet posto! Više nego Kina, Rusija i Indija zajedno! Od svih aktivnih satelita preko 50% su El Grandeovi - preko 5000 satelita!

 

Valuacija SpaceX-a je na kraju godine porasla na 180 milijardi dolara - što je postala najveća IPO valuacija neke kompanije u ljudskoj istoriji.

 

Zbog svih ovih stvari Maskova lična "neto vrednost" je porasla negde oko neverovatnih 250 milijardi dolara (dostigavši u jednom trenutku tokom godine i 320 milijardi) - još jedna od njegovih jedinstvenosti je da mu portfolio čine gotovo isključivo deonice NJEGOVIH firmi. Da bi se ova cifra razumela u perspektivi - to je otprilike oko zbirnog GDP-a Srbije iz poslednje 4 godine, ili oko 2.5 PUTA ukupne vrednosti SVIH stambenih jedinica u Srbiji [1]. To je mera dodatne vrednosti njegovog ličnog inputa za ljudsku civilizaciju, i, to uvek kažem, treba biti zahvalan što živimo u jedinstvenom vremenskom trenutku gde postoji mesto gde je ovakvo nešto moguće. U svakom drugom vremenu i mestu on bi davno bio zatučen plemenskim toljagama i izboden vilama, i ništa od njegovih proizvoda ne bismo imali.

 

 

Drugo, poslednja godina dana - i malo jače, od kada je otčepljen Tviter - deluje kao da se Zapad otčepljava: trenutno imamo nekoliko neverovatnih tehnoloških proboja koje palanka nije uspela da zaustavi, od AI-a preko satelitskog interneta do biotehnologije/vakcina i vraćanja nuklearna energija itd. Palanka ne uspeva ne zato što neće već zato što deluje da se rast prvi put od 1971. toliko ubrzao da ne može da ga stigne - da li se radi o nekom pandanu druge kosmičke brzine videćemo brzo. Ali ako i u 21. veku budemo imali roaring 20s mislim da je jasno šta će biti njihiv simbol:

 

 

[1] ovaj podatak ne postoji nigde, do otprilične cifre o tome da je ukupna vrednost stambenog prostora u Srbiji negde oko 100 milijardi dolara je došao kolega koji je preko tog zadatka pokušao studentima da objasni logiku rešavanja čuvenih "fermijevih problema" koji od ispitanika zahtevaju da procene veličine o kojima nikada nisu razmišljali (koliko ima klavir štimera u Čikagu, koliko se godišnje proizvede fudbalskih lopti ili kvadrata pice na svetu, itd) a koje na dobar način testiraju inteligenciju, numeričnost, analitičnost itd, te predstavljau gotovo savršen test recimo na razgovorima za posao i slično...

Ispostavilo se da je cybertuck sklon rdjanju

Tesla plasira svoj Cybertruck kao vozilo budućnosti. Sam Elon Mask kaže da je dizajn inspirisan žanrom Cyberpunk filmovima kao što je "Blade Runner". Međutim, da li je električni kamion zaista dobro opremljen za život u postapokaliptičnom svetu, čini se da je to najblaže rečeno sumnjivo.

Telo je možda otporno na metke, ali ne može da se suprotstavi podmukloj opasnosti odozgo: kiši. Kako brojni vlasnici Cybertruck-a izveštavaju na internet forumima, njihovo vozilo počinje da rđa posle samo nekoliko nedelja.

 

Ažuriranje softvera za 1,6 milijuna automobila

Kineski regulator tržišta naredio je Tesli da povuče modele S, X, 3 i Y.

Postoje problemi sa sustavom pomoći u vožnji i zaključavanjem vrata.

Piece of... je bio suspendovao nalog zeni Navaljnog, pa kada se proculo i ljudi poceli da pisu o tome, nalog je reaktiviran... sve u cilju slobode govora.

[deez nuts.]

Jasno je od prvog dana da je Putinov i Trampov shill. 

[Dzoni_m]

Ajde ne dramite, suspenzija je bila automatska neki od zastitnih mehanizama je blokirao nalog iz ko zna kog razloga, vracen je odmah cim je osoba sela i proverila rucno. Pravite od komarca magarca. Desava se svaki dan, od twitera do bankovnih racuna. Nije prijatno ali bolje false positive nego neko da zloupotrebi.

"defense mechanism against manipulation"... sure

 

Mislim, mogu da banuju koga hoce, njihova platforma, njihova pravila, njihova stvar... ali posle svih onih bs koji se pojavljuju tamo, neka ne prica da je za slobodu govora jer ga to cini licemerom.

Automatika na tviteru cini svoje: ako suvise njih prijavi neki post ili autora - sledi mu privremena ili trajna blokada.

Tek kada se digne buka onda se aktiviraju moderatori i razmatraju situaciju.

Ne mislite valjda da neka grupa ljudi cita sve objave na tviteru?

Nije to forumce sa brdovitog Balkana gde se pokace clanovi i oko nacina zamene sijalica.

Tako što ćeš nalog da izdvojiš iz automatskog blokiranja. Piece of cake.
