thermal constraints seem to be increasingly the dominant constraint in computing!
does it merit liquid cooling or something even more exotic?
Elon Musk
@elonmusk · Aug 19, 2020
Absolutely needs liquid cooling. We’re applying our experience cooling half megawatt drive unit power electronics in cars to computers.

That’s an error in Canada. The lease payment is specifically lower than loan financing, as Tesla expects to repossess the car. This is essentially a bet on residual value. If you believe residual value will rise, buy on loan, if you think it will drop, then lease.

Are you going to push the booster to go above 10 flights or maybe put it on display at SpaceX HQ?
Elon Musk
@elonmusk · Aug 19, 2020
We will push for ten flights with Starlink

Almost never need to replace whole engine, but some individual parts like turbine wheels need to be replaced over time. Similar to a jet engine.

Well and based on your job listings, you want it to be a tropical resort some day right? Will that be for the public, employees or just customers?
Elon Musk
@elonmusk · Aug 19, 2020
Mostly for employees, but we’ll support public access whenever it’s safe & secure. Public support is critical to making life multiplanetary.

Now that you’re at 6 flights, still think 10 is possible? What do you think will be the limiting factor that will end their service life span?
Elon Musk
@elonmusk · Aug 19, 2020
I don’t want be cavalier, but there isn’t an obvious limit. 100+ flights are possible. Some parts will need to be replaced or upgraded. Cleaning all 9 Merlin turbines is difficult. Raptor is way easier in this regard, despite being a far more complex engine.

I’ve been working in Boca since Sunday. August heat & humidity in South Texas is intense! If you think of it like a tropical resort, that makes it better though.

Don't know if you've heard @elonmusk but there's an offer on the table from @comma_ai about Dojo

Dojo V1.0 isn’t done yet. About a year away. Not just about the chips. Power & cooling problem is hard.

Just how scorched was #Falcon9 B1049 after its 5th flight? Here's a refresher from its last return to port.
It's incredible what these boosters are able to endure, only to be sent right back to the launch pad!
Stay tuned for the first ever *6th* return of a Falcon 9 booster!

I think he just means the regular raptor beats the hot gas thrusters in performance for the maneuver (stemming from liquid prop and pumps which lead to light tanks... As opposed to the pressure fed hot gas system with heavy tanks)

Raptors will only do majority of the work flipping on the first couple flights right? Won't the hot gas thrusters do more of the work eventually?
Elon Musk
@elonmusk · Aug 19, 2020
It’s counter-intuitive, but Raptor has so much thrust at high Isp with liquid (high density) propellant & pump-fed (light tanks), that it beats hot gas for the flip. That said, hot gas beats the heck out of N2 for orbital manuevers & stabilizing ship if landing in high winds!

ULA has said that you need to refly a booster ten times for the economics of reusability to make sense. SpaceX is now up to six with Falcon 9.
Elon Musk
@elonmusk · Aug 19, 2020
Payload reduction due to reusability of booster & fairing is <40% for F9 & recovery & refurb is <10%, so you’re roughly even with 2 flights, definitely ahead with 3

Center locking F1 style nuts require a HUGE torque wrench and a HUGE nut (~70mm or more). Will one come with the New Roadster and will all service centers have one available that can torque the single nut to specs (over 300+ lb-ft)
Elon Musk

Yes, it will have huge nuts haha

My favorite is one in tension, other DoF in compression. New Roadster wheels will only have one nut.
