Tesla Cybertruck

There is a rock boring tech called PETRA that should aid infrastructure

Tunneling robot speeds installation of underground utilities, aiding resilience efforts

Robotics company Petra said its technology allows it to bury utilities deep below the surface and in difficult terrain, expanding the reach of the utility grid and providing greater resilience against climate-related disasters.

The Boring Company is worthy of support….having to dig trenches along the side of the road should be avoided.

The more things you can put out of the weather—the better.

Well now if I were aerospace corporate material (which I *most decidedly* am not) I would counter with founding the Snoring Company, and opening a competition as to what precisely might be its objective, i.e. combatting silly libertarian brain-rot as a purely random example...

Thereby hangs a tale.

A lot of NewSpacers strain at gnats about Orion's heat shield (this the same bunch that cheered books like "Safe is not an Option.") One out there will demand proof as to the points I make--but when I provide links as I do here--he doesn't like that either...especially when I brought up the fact that SS/SH must do something like the never-tried Shuttle RTLS where hydrolox rockets don't have to maneuver violently. It turns out that cryogenic liquids really don't like being sloshed:

O/T rant over.

It looks like Bezos wants his own version of Cybertruck:

So two models of Tesla are to be discontinued, the Cybertruck is on the edge, and the Optimus robots aren't nearly as advanced as what Musk has been claiming.

Anything else of note?

Regarding the Telsa Semi (incidentally, it is classified as a Class 8 truck under the US GVWR system):

The lack of a sleeper cab precludes high value team driving, as does the total lack charging infrastructure. That pretty much leaves local route driving, even the lack of a trustworthy power source for a reefer trailer precludes food distribution companies like Sysco from using it. The whole point of a reefer trailer is the self contained refrigeration system powered by a low RPM Kubota diesel, for instance. For European ferry routes, electric semis will be abandoned for years to come because of the fire risk. The same fire risk precludes the use of an electric semi to haul gasoline or propane tankers.

Finally, you have the poor economic of fast charging, where it costs more to charge an EV on a highway trip. Tesla just revised their estimate of average residential power rates upward by nearly 30% recently, and the costs of installing massive substations at truck stops will increase costs more. Automotive fast chargers already charge 3 times as much as commercial rates and that’s without the massive substation and upgraded supply lines needs for a semi scaled charging station. Not that truck stop chains are even interested in hosting charging infrastructure. The liability of the thermal runaway on a semi sized EV is astronomical, with a single semi having the potential to take out an entire mammoth trucking depot. If insurance costs are strangling EV car sales, semis look like a compete non-starter.

Overall, I’m more optimistic about the upcoming April Fool’s Day announcement of the Tesla Roadster than the prospects of the Tesla Semi. I don’t think owner operator truckers are any more “excited” about the EV semi concept than modern doctors are about the health benefits of smoking. Tesla/LG’s LMFP battery tech is no where near as established as Chinese LFP battery tech and LG is too associated with NMC battery chemistry. I think it would actually take a total and permanent ban on NMC batteries in Class 8 trucks and the scrappage of current NMC EV automobiles and light trucks to allay concerns over thermal runaway.

It is the wrong solution anyway....what you want is a self driving trailer.

We have all seen the back axles slide--the tandems.

I bet you could slide a whole propulsion module under them the same way. You would need one driver mechanic assigned to a sub-fleet.

The idea is for that man to dead-head about and simply replace the module. Slide in the new one, tow the old one to a shop where repairs are made indoors. Tow the trailer if need be.

A self driver could have doors at either end and itself towards standard trailers.

The slides are trapped under the trailer by welded in parts on both ends.

Now, if we could make a tow vehicle that was just the two back axles of a semi, that might be viable.

This one's in agreement - it really only makes economic sense in California with subsidies and there still isn't a 'Megacharger' network.

The marketing is all wrong - it's really a cybersuck! But please, don't tell Elon - being the genius that he is, he'll figure it out in due time...

A self powered dolly under the fifth wheel.
That would be best in areas where you have intense cold.

That saves folks from freezing out in the middle of nowhere.

Good for this too perhaps

In the case of “Iron Duke” engine powering this pristine S-10, “simplicity” means that a single cheap plastic timing gear invariably breaks down. It’s press fitted to the end of the camshaft, so it quite a bit of work to fix. Most people simply junked these Iron Duke powered vehicles before 100,000 miles. Not worth the time, money and trouble. This is precisely why so few 1980s mainstream 4-cylinder domestic products are still on road.

I’m absolutely puzzled why anyone would pay $18,500 for even a pristine 4-banger truck that can’t keep up with modern traffic? Very specific nostalgia? Nobody misses those sideways facing miniature rear jump seats which have to be horrifically unsafe in a crash. Or a horrifically cramped and narrow interior that can only be described at Detroit’s misguided attempt to copy the Japanese. Well, the Japanese built narrow cars and trucks because their government imposed high road taxes on vehicles wider than 1700mm. With no similar incentives, GM was only just blindly copying and it’s hard to see how an early S10 was an improvement on the previous rebadged Isuzus, other than providing employment to UAW members. That’s not to say that a turbocharged GMC Syclone or Typhoon SUV isn’t collectible or appealing, just that the regular S10s really weren’t even at the time. Oddly enough, even a Syclone offers about same acceleration as the cheapest F-150 with the Ecoboost V6, in a far less comfortable, less practical, less safe and far lower fuel efficiency package.

The really odd thing is that GM continued building the S10 for over 20 years…. And then replaced it with a similarly narrow and cramped first gen Colorado. And not for any obvious reason like shared parts and tooling. The Japanese had long since moved on from tax based width limits, but GM spent a fortune on a clean sheet of paper redesign that almost exactly replicated the packaging of the S10. At least Tesla has only engineered the Cybertruck once. If they make the Cybertruck for 20 year and then make the same mistakes on a completely new design, then, and only then, will Tesla reach pre-bankruptcy GM’s levels of insanity.
 
I think what he means is body style as much as anything else. A skilled enough person could put anything under the hood...what we should demand is right of repair, and for durable goods to actually be that again.

And all objects on that vehicle optional...yes, that should include seat belts and chosing to not have a bomb in a steering wheel. The one good thing about my state is that it doesn't harass its motorists.

I got my airbag neutered and run a straight pipe because I can't afford a new catalytic converter...but I am still cleaner than someone with a new Gigantor every two years since my car is a 1992 and I plan to keep it until the Sun goes Red Giant.

The engine of my Buick LeSabre would be perfect for a little light duty truck.

If you want something for heavy duty.. it's called a Peterbilt.
