Elon Musk – CEO of Tesla Motors and SpaceX | Entrepreneurship | Khan Academy

Sal Khan: First of all I want to thank Elon for being here and still hungry Elon Musk: Absolutely! You haven't eaten dinner yet We didn't treat you well Elon: Sorry to be late Thrall: where where Elon: Just came from the Tesla factory in Fremont Thrall: Really? What went wrong? 【laughter】 Elon: There are always mistakes Thrall: You must. . . Elon: at any moment There will always be something wrong Thrall: Yes Elon: Because there are too many things going on at the same time Thrall: Yeah So one of the hardest problems with cars is It has thousands of independent parts Thousands of unique parts Even if one is missing You can't build a car Yes it is Today's farce is We don’t have a three-dollar USB cable So we can't finish building a car because That is. . . . The assembly line stopped running Yes overall Because it is part of the electronic circuit So the interior decoration cannot be installed without this wire We can't make some cars But no interior decoration Means you have to put them in the yard Thrall: The second-hand price will not be good Elon: It can be done but The bad thing is that the process is very messy Yep It’s very inefficient and can’t do that You can't change the production line You must send someone out Hundreds of cars had to stay in the yard so we- That wire is particularly sinister It is located under the carpet in a very difficult to access place And it's only worth three dollars So we have to send people to the entire Bay Area Go buy a usb cable Like going to Radio Shack? It's to Fry's…

Oh Fry's that's better It’s hard for you guys to be in Fry's now Bought a USB cable Oh, is it so? We just bought them all that's good So that we can continue to produce I don’t blame anyone for this story Basically, Chinese suppliers We have plan A and plan B Plan A is a normal supply chain process But what the supplier does is Instead of packing our parts into a package They will sell our goods Put it together with other company stuff Transported over The package was shipped from China to Los Angeles on a super slow cargo ship When it arrives in Los Angeles, other people's things can't pass customs Oh They also don't let our things pass Are they in a bucket of fruit? I don't know where they put them in It must be something that the customs doesn't like There is a problem with the customs declaration materials, etc.

So they stayed there for two weeks We still have plan B We call them Hi you have to airlift us some wires Because they are very small wires We are in contact with their U.S. branch And place an order from them They communicate with the Chinese headquarters Since this is another batch of parts This doubles the value of the order It exceeds the credit limit we have Oh yeah you have to So I was bounced back They did not ship Amazing. . . So someone is going to lose his job I'm just kidding. . . You don't fire anyone I mean this is messy I will arrive at around 11 this evening what! Something like this always happens Is it just a special case? That's just an example and there are many That is a good example because it reminds me of I am always fascinated by what you do I think i will start like this If you enter this industry, I mean Enter the automotive industry? Enter the automotive industry and enter the merger of NASA (NASA) . . . Not a NASA merger Become a NASA partner Please note that we will not annex NASA Yes you will not annex NASA They are an independent organization But you will become a major service provider for NASA Obviously Internet payment and universal payment I mean these are three completely different areas I think many people don’t take a person seriously If they have a business plan in one of these areas correct Yes you can take your time What is yours.

. . I mean do you always do this? What makes you Want to revolutionize in three industries? When i was in university I don't expect this It’s not like realizing a long-term dream When i was in college i thought Which areas will have the greatest impact on the future of mankind My opinion is that the three areas will be Internet sustainable energy and space exploration Especially whether human beings will become multi-planet animals This seems to be very different from the future we expect Or we will go to other planets Or we will be limited to Until the final demise It's not that I am pessimistic about life on earth The situation may be good…so far so good Yellowstone Park will explode every few hundred or thousand years Some people know this 700,000 years… Yes… yes… the super volcano is going to engulf the world It's true… I know what you're talking about We read the same book i know Definitely Just give enough time some bad things will happen The existence of human civilization is actually very short These time measures seem to be very long But they are very short in terms of evolutionary time One million years is nothing in the evolutionary time measurement The earth has existed for 400 billion years That’s actually just a very small period of time But for us it will be I mean can you imagine If human civilization can continue One million years of development at the approximate speed of current technology development What will happen I think we will either go extinct or go to many planets We should be like this We have two options such This is the most epic way of thinking about problems That's what I think…

How do you make it concrete? How did your ideas become SpaceX, Tesla and PayPal? I think about these things abstractly I didn’t expect that I would work in these fields But I want to participate in at least one of them First of all, I think the most likely one is electric cars So my area of ​​study is advanced capacitance This is a capacitor with an energy density that exceeds that of a battery Because they have high power density but low energy density We have a class on this topic…

Thrall: We should organize a class Yes it is Obviously, if you can make a capacitor that approximates the energy density of a battery And very high power density and near-infinite cycle and lifetime Then you have an amazing solution for energy storage and mobile applications So I once planned to do research on it And try to take advantage of those Equipment used to make advanced chips and optical instruments To create ultra-accurate capacitors at the molecular level Is this what you planned to do when you were in graduate school? Have you studied at Stanford for a short time… PhD student in applied physics? Applied Physics and Materials Science…

Thrall: This is it Since then you have been thinking about doing something in this field Actually that is Research on energy storage solutions for electric vehicles Yes it is I actually work for a company called Pinnacle Research in Silicon Valley It is made of advanced capacitors They are electrolytic capacitors It’s actually pretty good. They have the same energy density as LED acid batteries. It's great for capacitors But they use ruthenium oxide I thought The world’s annual output of ruthenium is only one or two tons This is not a scalable solution But I think there may be some kind of solid solution As I said, using equipment for manufacturing chips That's a basic idea This is that kind of ideas I'm not sure if there is a possibility of success You know…like you can't It's hard to set boundaries for that question and say OK… You seem to be saying that I think this will definitely fail This is another way of saying No i don't think it will fail But I am not sure that success is a possibility ok, I understand You know in general If I start to do something, I hope I can know Success is at least possible correct Because it is certain that failure is a possibility Yes it is Ideally you want to determine it and say Success is within the scope of the result Yes it is But I was not sure if success was one of the possible outcomes I think academic success is very possible Because you might publish an article Most articles are useless We have some don't be angry I mean how many doctoral dissertations will be used Has it been used by someone before? That's pretty good
