So now the question is what price is Tesla charging to supercharge. Cost Of diesel is 5.5/gal, fully loaded truck gets 6.5mpg. So will Tesla hit lower than 2kw/mile? Will each kw cost 46c or 8c according to Teslas slide? This makes a huge difference. 8 cents might just be what electricity cost charging at "home", home being the fritos factory for example.
They’ll make it as low as it makes sense from a Tesla business point at any given moment. They won’t sabotage the company with a price point too low and they won’t be robber barons with an exaggerated high price point.
 
Except the new are, at least in part, replacing the used.
At the other end of the spectrum, it could be a fleet change of zero to negative (220k new, 220k new->used, 60k used->used, ?k used->scrap)

Fair point, most of the used could be ones that were traded in/sold once they bought new ones. Regardless, the TAM would have to be at least 250,000 a year. And again, if the economics of the Semi are what we think they are, there will be a higher rate of replacement than normal (which is the case when there is new disruptive technology).
 
No, the big question is why you’d think they just did it now for the first time? 🙄

This is what happens when you get into a negative headspace about someone. All you see, all you can imagine, all you think from that point forward is negative. You’re no longer looking for any truth that isn’t negative. And you know exactly what I’m referring to.

First of all, they need current data/pictures/video for the presentation. Something they validated 3 years ago on a prototype isn’t worth a cob of corn on Dec 1 at the event.

Second, throwing out little crumbs prior to an event is the Elon way, unable to always control his enthusiasm about accomplishments of the team.

Third, throwing out information like this generates ah, excitement, interest, even disbelief - I’ve got to see this with my own eyes.

Fourth, it doesn’t actually matter at what point they prove their specs. This isn’t GM/Ford/and the like. Tesla actually aims for the specs they put out with their prototypes and then tries to exceed them with the final product. That’s actually sentiment right from Elon and most times they accomplish it.

This is a mic drop moment. Stop trying to rain on it.

I think the simple explanation for his tweet was simple: to build buzz.

He didn't say it was the first time it had happened.

This is no different to when they leak photos of a new phone before the announcement.
 
So the Twitter thread is locked and we can’t talk about Twitter here? How does that make sense? I guess go to some other unnamed social media discussion forum?

Btw, completely related to Tesla post: For those worried about software engineers running away screaming from Tesla (and Twitter), Geohotz gives his opinion on his twitch livestream (he’s stream his coding??? What a time to be alive!), 20 seconds long: georgehotz - working at twitter

tl;dr All is fine.
I’d hardly call what was going on ‘discussion’. 😉

It is an amazing time in technology history to be alive to witness the advancements and disruptions.
 
They’ll make it as low as it makes sense from a Tesla business point at any given moment. They won’t sabotage the company with a price point too low and they won’t be robber barons with an exaggerated high price point.
Trucking companies or truck stops can install their own megachargers if they think they can do it less expensively. It’s only electricity after all. It’s not like they would have to create an infrastructure to transport, store and transfer a cryogenic explosive.
 
Why do they hate DEF? Cost, or just rebellion against a govt. mandate?

Here's a random google result for "semi def". If it's anywhere near accurate I wouldn't want to deal with it either. The phrase "Do not taunt Happy Fun Ball" comes to mind.

HOW DO I KNOW IF DEF IS BAD?​

When DEF becomes contaminated, your truck’s performance will suffer. How can you tell when DEF needs to be replaced? Here are a few red flags:

  • Selective catalytic reduction (SCR) system malfunctions
  • Illuminated dashboard warning light
  • Increased diesel fuel consumption
  • Decreased effectiveness of DEF
  • Damage to DEF dosing pump, diesel particulate filter, and other components
  • Potential engine de-rating or shutdown

PERFORM ROUTINE DEF REPLACEMENTS​

Replacing DEF is one of the easiest ways to prevent increased consumption and possible damage to a truck’s engine and systems. DEF has a shelf life of 12 months in perfect conditions. Whether you’re managing one truck or a whole fleet of trucks, routinely draining the tank/s and refilling with fresh fluid helps prevent problems down the road, especially if you’re planning to sell and want to keep a new buyer happy.

MONITOR THE UREA CONCENTRATION OF DEF​

Keeping diesel exhaust fluid pure is essential to its quality. Even contaminants around the fill cap can be a problem. Before undoing the cap to add more fluid, be sure to wipe the cap and the area around it. This reduces the likelihood of dirt and other debris falling into the tank and compromising the fluid.

How do you monitor the quality of DEF? You can use a digital refractometer to check the urea concentration. Ideally, the concentration should be between 32.5 and 37 percent urea. You’ll likely notice the above listed red flags in accompaniment with drops in concentration. Although one can be somewhat pricey, a digital refractometer can help you get the most from your truck’s DEF despite the short shelf life.

HANDLE & STORE DEF CORRECTLY​

Mishandling DEF can render it useless. Certain metals, such as copper, carbon steel, and aluminum corrode when they come into contact with DEF. For this reason, it’s important to use manufacturer-recommended stainless steel or plastic totes for storage. Additionally, be sure to do the following:

  • Keep DEF out of direct sunlight.
  • Store at a temperature of about 86 degrees Fahrenheit.
  • To prevent waste and contamination, consider storing DEF in 2.5-gallon containers vs. bulk containers.
  • If you need bulk storage, create a closed loop system — or a fully sealed system that makes it easy to refill DEF storage containers without exposing the fluid to contaminants in the immediate area.
  • Never use tap water to clean the components used to dispense DEF. Instead, use distilled or deionized water and follow up with a DEF rinse.
  • Never use the same equipment for dispensing DEF to dispense another type of fluid. Use the same equipment each time and for nothing but DEF.
 
My wife’s works as an engineer and makes enough money to pays for everything for the daily living and for the kids. She has a secure pension fund. I bought the house and the Model Y and purchased 250k of TSLA during the pandemic crash and 250k on margin. It was nice to see that almost 10x before it reversed. My mistake was to refund gradually my margin but at the time time buy more TSLA on every dip it went -10% to -20%. So my margin never reduced. Instead of selling shares to convert to LEAPS, I doubled my workload to have sufficient funds to have sufficient margin to back my puts I sold for Jan2025 at 430 strike price. These are my reverse-LEAPs play to clear my whole margin today and it’s give me 2 years to make the money to buy these shares if for whatever reason the SP doesn’t recover. I didn’t know how much longer the stock price can stay irrational but they say it can stay irrational longer than we can stay solvent. The advantage of still working is that my solvency increases considerably over time.

I discourage margin usage to everyone who is starting to invest, unless they are ready to lose every last cent they have invested. Once that said, it is still not fun to see that money disappear even if you don’t need it and ready to lose it all. This reminds me when I went to six flags with my kids last month and we did all the roller coasters 3-4 times straight and had so much fun until we went in the condor and the Chaos, after spinning too much the head down my older boy started vomiting on the way back home in the Model Y while I was driving with nausea. Margin is fun until it’s not.
My takeaway from that is Six Flags should have a “Margin Investor” ride.
 
Potentially, the prototypes were using smaller packs due to non-optomized design. This would let them test and develop all the other features without needing maximum energy density. For example, four 100kWh packs stacked together.

In parallel, they would have the pack design testing on thermal and electronic load systems to find the limits. Hours of continuous high load/ uphill testing. Hours of start/stop urban tests. Things you can't do in the real world.

Not all used trucks are equal. The older Pre def trucks sell for more than new trucks with def so I think you will see the oldest def trucks shitcanned first. There is very little value on a high mileage def semi with known issues.

We have replaced a def pump at 300 hours, 3 days downtime waiting for a pump.
 
A quick search suggests there are currently ~2 million 18-wheelers on the roads in the US. Annual TAM of 100k-200k?
That is about right. Here are the annual USA numbers:

It seems that European electricity prices are creeping upwards again. Tomorrows peak pricing approaches 40 eurocent/kWh (ex vat and transport/distribution costs). A couple of weeks ago it was between 10 and 20 cents.
Gas pricing has slowly gone up again, now at 125 euro/MWh. When it was still going down a couple of weeks ago it went below 100 euro.
We’re probably seeing the effect of winter temperatures finally normalizing, and gas and electricity going to normal seasonally high consumption. This probably doesn’t bode well for European inflation.
The price lull the last few weeks quietened the discussion about energy prices, but that will be over soon I guess.
France is still behind schedule in reopening their nuclear power plants, currently at 30GW production (50% of capacity).
 
If 500 miles fully loaded pans out, the FCEV semi is dead. The semi might turn out to be the most impactful product Musk has ever brought to market and that’s saying a lot !!
I say that the FCEV semi (or passenger car for that matter) is dead regardless.

The Tesla EV semi kills the diesel semi for the same use case.

Indeed.

I suspect this tweet was regarding some sort of "landmark" test, such as the documented case for "officially" determining range, a test of the first "production" truck off the line, re-validating their (apparently) new motor configuration, etc...

There's no way they haven't done such drives before... many times....

It is a horrid solution that accomplished nothing but forced people to go to manufacture for service. Literally. Have to have a Mercedes tech come to site . Or cat or ford or John Deere. Horrid. Expensive, accomplish nothing for environment

.40/kWh isn’t actually all that high. Here in California, our peak pricing is around .58/kWh the last time I checked. Also our nat gas prices are also going up since we are selling so much to Europe now.
 
A page or two of posts about all sorts of things concerning them big ass semi trucks. All that insight!
And yet the only thing we need to know as investors is
Tesla can sell all the trucks they make for the next five years. (And that is ALL we need to know. And we knew that before talking about pee pee in the air.)
The thing we don’t know, I think, is current pricing for the semi. Maybe we’ll get that December 1st. Nonetheless, there is a long line of companies that want to trial the semi on a 3-10 truck basis. So current production volumes are sold.

Maybe true, but it gives depth to why this is so. $75k a year in fuel savings.

Vs cars where things are far less clear to me. In fact I can make a pretty good argument that with the high price of a Tesla it is not cost effective vs a high mileage Corolla or civic. I will never recoup the added cost.
 
Why do they hate DEF? Cost, or just rebellion against a govt. mandate?
There are dozen of parts that are added to diesel trucks to limit NOX emissions. DEF is a fluid they have to add at truck stops every so often, it's like $3 a gallon on top of $6 a gallon for diesel. The new emissions equipment (same stuff in question from VW diesel gate) causes added cost, maintenance issues, and if it's not operating will cause the vehicle not to start. Most of these emissions limiting hardware/software shorten the life of a diesel engine or cause massive costs when things must be replaced.

When EV trucks become mainstream it will eviscerate the existing companies for all the reasons you can imagine.
