China & Asia Pacific Supercharger usage above pre-covid highs. North America catching up fast. Europe slightly behind.

Per well-placed sources, @ElonMusk's Boring Company is confident it will expand underground transportation system to include tunnels between airport and downtown Las Vegas, in addition to proposed stops at Wynn and Resorts World.

Does the Raptor use a high dP injector to allow throttling? Is this how you can get more thrust out of a non-throttleable version, by using a low dP injector?
Elon Musk
@elonmusk · Jun 15, 2020
Throttling is done by adjusting flow to the ox and fuel preburners. The lower limit of thrust is ox & fuel turbopump injector preburner “stiffness”, essentially when do the preburner elements start flaming out.

Tank didn’t burst, but leaked at 7.6 bar. This is a good result & supports idea of 304L stainless being better than 301. We’re developing our own alloy to take this even further. Leak before burst is highly desirable.

Also somewhat dependent on injector strategy and mixing efficiency. L* ( characteristic chamber length) determines residence time and you only want this as long as it needs to be to react the propellants.
Elon Musk
@elonmusk · Jun 15, 2020
Yeah. Merlin, using a single pintle injector with cold, liquid propellant, needs a longer chamber than Raptor, which uses a large number of coaxial injectors, despite Merlin being less than half thrust. Propellant enters Raptor chamber as hot gas that’s already mixed.

Looks to be 100 percent frost covered. Venting from the top and bottom. Big question is whether they push it to failure today to see what pressures the new tank can sustain.
Elon Musk
@elonmusk · Jun 15, 2020
That’s the goal. There a few known weak points on this test tank, probably capable of more pressure. The second test tank to follow shortly has addressed the weak points.

Just curious what the latency is on this? Will I be able to play games like Warzone, fortnite, or NBA2K? Thanks....
Elon Musk
@elonmusk · Jun 15, 2020
Around 20ms. It’s designed to run real-time, competitive video games. Version 2, which is at lower altitude could be as low as 8ms latency.

Looking up to the skies with open eyes!
Went to HQ and set up a Starlink terminal that connected to the satellites orbiting overhead. Simplest out-of-box experience imaginable.
Can't wait to upgrade my broadband later this year!
Elon Musk
@elonmusk · Jun 14, 2020
It will get even simpler. Just two instructions for Starlink: plug in & point at sky. Can be done in either order.

Definitely. Starship will make about anything else pointless. It’ll be cheaper to fly than the Falcon 1 even (eventually). It might take a few more years to get to thay point, but when it works out as planned it’ll be orders of magnitude cheaper.
Elon Musk
@elonmusk · Jun 11, 2020
Exactly. Chartering a dedicated 747 flight around the world costs less than buying a small, single engine turboprop plane. In the same way, a giant reusable rocket flight is way cheaper than a tiny expendable rocket that can be used only once.

Battery industry is world champion at bs. “Lithium-ion” doesn’t really mean anything. What matters is cathode & anode material. There are many choices, but nickel cathode with carbon-silicon anode works great.
