The amount Elon has delivered so far this year alone at Tesla and SpaceX is tremendous then you see a headline where he landed a 50+ million tunneling deal on the side because why not. Staggering.

I'm surprised I haven't read any talk of, or even speculation about the idea of the Boring Company getting involved with the tunneling required for CA's high-speed rail project (for the Pacheco Pass and Tehachapi Mountains segments). My guess is that perhaps very different tunneling technology is required given the geology or something. Or maybe it's just that Elon Musk hates trains and loves cars way too much.

TBC makes small tunnels, enough for an SUV, likely not big enough for a long distance train.

Cool but my thought was that load sharing between cars was caused by contended grid connection rather than anything in the supercharger itself?

Having 16 * 250kW grid connection (4MW) will be super expensive (in terms of connection speed) and slow to provision in many places. It's a similar amount of power as a data centre and power connection is the slowest and hardest part of that, hence why I assumed they had lower grid connections which would be easier to source from local power companies.

By how much would using the supercharging feature reduce the overall lifetime of the batteries? Lithium cells aren't immune to the memory effect, which would only be shortened with the high heat associated with pushing a significant amount of power through the car. The very first issue of Popular Science magazine I received as a kid had the Tesla when it was still the modified Lotus Elise with the clickbait-y title a…

What are you, like 13?

His companies delivered, not him alone. Take nothing away from the man though, he works insane hours.

But he's the one coordinating it all. Which is impressive. It's often difficult to run a single small business let alone a single large project/company. It's quite outstanding to be able to run multiple of them simultaneously.

The main info is missing in this PR release though. Is this a hardware upgrade or a software update? Looks like a hw upgrade, if so are they upgrading all their charging stations? Or did they already do it? How long is the upgrade going to take and how much will it cost?

It's a completely new hardware design with the power cabinets now using industrial inverters. The old v2 cabinet used a bunch of Model S inverters. The power posts (the white things with the cables on them) are the same as v2 externally, but not internally. They're not retrofitting stations, but all new stations (other than Urban Superchargers, which they will still install in urban locations) will be v3 hardware. Fo…

Said older models software upgradable to 145kw.

The on-route battery warmup is a cool feature that I hadn't realized they'd implemented.

Is this compatible with European charger standards?

This is awesome. I'm particularly happy about the on-route battery warming. Since I can't charge at my apartment, I tend to charge my car in the morning. If it is around freezing temperatures, it will charge at a rate of 0 miles per hour.

Can you speak more to this? Similar situation. Interested in a Tesla but live in an apartment without a station but during winter have well below freezing and sub zero temps. Seems difficult.

Looks like 100kw less than already existing non-Tesla 350kw chargers.

0 cars currently shipping can handle 350kw charging. Delivering lot’s of power is fairly strait forward, designing cars to safely handle that is much harder. Further, as infrastructure that needs to work, the 1MW of power supplying these chargers is the more important upgrade as charging multiple cars was already power limited.

250kw is not that much higher than 175kw - https://electrek.co/2018/12/18/audi-e-tron-155-kw-fast-charg...

> more than 99% of the U.S. population is covered by the network The coasts, the south, and interstates highways. Most of the US area, where you can go in the USA, is not covered.

These cars have ranges of 300-400 miles or more though. Tough to go that distance in a single trip without traveling through a populated area or using an interstate highway.
