#22Well 750kW with a 700kWh pack is only a bit above a 1C charge rate which .. is not terribly much at all. Not sure what this says about the other statements in this article.

#23Why does anybody in the entire world want a semi with a 5 second 0-60?
You dont need a fast 0-60 in a family car either but people buy Tesla sedans for that purpose all the time.

#24This seems kind of par for the course. What I find strange is that there are busses[1] operating economically with similar time of use (but not top speed) requirements. The whole "car parts scaled up to truck size" is super on brand for their chief technologist. I'm also seeing a bunch of Rivian trucks and Ford E150 lightnings on the roads around the Bay Area which, for me, doesn't bode well for the launch of the Tesla truck either. If the Starship blows up tonight I imagine that's going to add stress too. I really wish Elon would pick cars or rockets and focus, that could really help the world. I'm not holding my breath though.

If every house had a fast charger, that would be a sensible concern. But everybody turning their dryers on simultaneously during off-peak hours isn't something worth worrying about. Especially since it's not going to just happen all at once some day.

Compounded by getting rid of natural gas for cooking and heating.
It's fine to say that electric is simpler to deliver and more efficient in theory, but our grid is not even a fraction ready for that, and heat pumps and induction ranges are a whole order of magnitude up the tech ladder from boilers and gas stoves, and by going all electric you lose the multiple sources redundancy which is literally a life saver.
I do actually welcome the cleaner future but I hate how people are pretending it's already here and making regular people deal with the discrepency.

1 MW charger per truck, if you need to super charge. Equivalent to approximately 1000 homes. This is a huge burden on the electrical grids, and Tesla or EV's get to hand that problem to someone else. The only way this makes sense at scale is if we had nuclear power, and charging was done at night.

They don't exactly get to push it onto someone else. Large loads like this come with demand charges. In some areas, they might be $5/KW, in others I've heard of >$10. A single megacharger would be $5-10k on top of the actual energy used.
It is high enough that I'd expect them to start thinking about battery buffers at charging sites to mitigate the cost.
That already happens at a smaller scale, with things like Freewire.

#28Looks like the design requirement for a heavy duty vehicle were not properly followed. Though that's how tesla builds something like software build find faults then itteriate. For light duty if you can get chinese $2000 truck with a hydraulic lift I think china is going to takeover the world's vehicle manufacturing markets. https://electrek.co/2023/11/14/two-years-after-buying-a-2000...
That's something that's basically equivalent to a golf cart with a bed on it. Hardly an example of anything useful except transporting some stuff around your own property.
FTA: "It’s fine if people want to call it a “glorified golf cart”, though I’m not sure I’ve seen a golf cart that can tow a boat, haul furniture, dump mulch, and that comes with creature comforts like air-conditioning, infotainment screen, power windows and locks, and a frunk."

Yea, i've read it but the point still stands. And there's all sorts of tricked out golf carts available with most of those features. Being able to bounce around your own property is cool, and there's many types of small vehicles for that, but they're not something you compare to a road worthy vehicle.

#30It's a prototype at the edge of what state of the art battery technology allows.
Kudos to Tesla for having the guts and endurance to try. This is relevant for Tesla and for the industry.
