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.

for sure: - closed stores - no profit - lied about FSD - stock down 30% - long-term investors exit the tunnel is a joke. we were promised something, but as always with musk, we get something completely different. i'm giving the tunnel deal 3 to 6 months before imploding.

About 4 months ago the narrative on HN was that Tesla will go bankrupt right about this time because they'd be unable to repay a loan. Read news recently that they paid it in cash.

Been seeing highly upvoted doomsday comments since many years about Tesla, like Model 3 was literally supposed to be DoA, it just feels so weird to me.

Fantastic tech. However, why do they insist on doing it in a closed proprietary way? Teslas growth is coupled to general EV growth. They can't possibly be arrogant enough to believe they will be the sole supplier of EVs if they win can they? Charging is the number 1 thing holding back adoption right now.

Even if we could charge in 1 minute, ICE fans would argue that they have to charge 3 times more often than with their ICEs at highway speeds and that they have to choose longer routes because of charger coverage. It's only part of the solution to increase charging speeds and fast charger coverage, EV also need 2-3 times the current range (i.e. 200-300 KWh batteries) to convince most people.

The much bigger news is they completely walked back FSD (full self-driving) into something that you have to monitor at all times by changing the description on their website. The release of a proprietary charger is somehow completely overshadowing that news. It's changed from driving itself around in a ride hailing network to earn you money while you sleep, to now making you always be in the car and pay attention and…

Hey, how about stick FSD up right up your jacksie and buy a different car. Tesla isn't for you.

When they added credit card readers to all the pumps?

My local Shell station recently switched from card readers to an app and QR codes. No thanks. If I'm really desperate I'll fill up there and go inside to pay (maybe 3 times in the past year), otherwise I now go out of my way to fill up elsewhere.

And those comments are understandable for a number of reasons. From an outsiders / non-economist's point of view, these things should not be possible. There's also an army of trolls hired by short sellers who would benefit from Tesla's stock losing value - at one point, Tesla was the most shorted stock out there.

I agree; it always makes me put my tinfoil hat on, and wonder how much of this comes from news planted either by competing car companies, or more likely the hedge funds who will profit if Tesla does fail.

No, you can't buy that service. Not even close. 400amp service is usually 2 200 amp panels. Done with 2/0 cable. It's rarely, if ever, 1 400 amp panel. 1. There is no way you would get "1000amp service" at 250v. It would be a minimum of 480v 3 phase (and not 1000amp). You may even want a lot higher, because as you'll see, getting that many amps is ... very very hard. 2. You can't even buy 1000amp cable gauge anywhere…

My local utility seems to offer it, though they prefer that you install a transformer. They also offer 3-phase for residential usage. Yes, this is in the USA. From what I can tell, most likely you'd get 480 volts at 500 amps. There is actually a home not far from me that gets 3-phase. It is hooked up to a commercial-style air conditioning unit (huge house) and has a separate power meter; the home has separate 2-phase…

(I'm going to abuse the hell out of terminology to make this understandable)

I'm sure there are some utilities somewhere that will offer you that :)

480 volt at 500 amps is actually fairly reasonable in terms of cable requirements (it only requires 800 kcmil cable, which, while, i'd never want to buy a ton of it, is not completely bonkers). I would be a little surprised if they offer 500 amps though, because that's a lot more than you'd ever need.

Remember that a 3 phase amp carries a lot more kilowatts than a single phase amp.

In particular, 20 amp 240 single phase = 4800watts But 20 amp 240 three phase is a factor of sqrt(3) more = 8313 watts

so 500 amp 480v 3 phase would carry 415692.19382 watts, while 500 amp 480v single phase (which nobody uses) would only carry 240000 watts.

So you'd be getting 415kw service out of that, not 240kw service. Which is a lot of power.

Usually i've seen them offer 250kw service (IE not in amps) and let you do the stepdown. This would step down to 300 amp 480v 3 phase.

240v 3 phase in residential areas is also more common (I can get it), but it's only 100-200 amp service at least here, and i pay for power factor, blah blah blah.

Tesla has repeatedly offered access to their supercharging network to any car company that wants to use it, but nobody has taken them up on it.

They claim that, but nobody knows the details.

The deal they offer other car companies may be completely unreasonable, who knows. They would still be correct that they "offered access" though, so it doesn't mean anything.

he's also a trendsetter. What's with Boeing and Blue Origin getting in on the commercial space race. Also he create the market for electric cars with new players like Rivian and old ones like Volvo, and load others I'm sure. Even some big players like Virgin Group jumped in on the Hyperloop thing, although I dont care about this as much.

Other players may create supply, but Elon can create demand. He's in such a unique position, imo.

Isn't that a waste of copper? My house has about 20 Amps (3.3 kW at 230 V).

There's no way you're only getting 20 amps to your house. A microwave will consume 8-12 amps. A desktop computer is around 3-5 amps. I don't know what my electric stove used when I still had one, but it needed a 40 amp breaker on its own.

The standard home contract in Italy is 3.3kW, at 230V it's less that 15 amps for a resistive load. The meter will allow you to go over the allotted power for some time before disconnecting you though (the amount of time is inversely proportional to how much your going over, and I don't think you can ever go over 4kW).

Heating and stoves are gas based (ovens usually not though); going over the limit is not usual, the only common problem is when using air conditioning in summer which is becoming more widespread, and so are higher power contracts (we're not talking more than 6kW, though).

According to my utility, I consume annually 2660kWh, that is 300W average, much less than the 1.2KW for an American household.

Note that for home contracts the limit (and billing) is on power, not amps, so using inductive or reactive loads will not penalize you.
