Odd, the article I read had this image: https://c1cleantechnicacom-wpengine.netdna-ssl.com/files/201... (or one like it), and looking at the video, it seems they had both on stage? Are there two models? It didn't seem to be discussed.

The page does say "300 or 500 miles" for the range. Sounds like there's multiple models to me.

Sure, and how you're supposed to charge them fast enough to charge incoming trucks > a charging station for 8 semis will need a dedicated 20 MVA 20MVA is approx. 20MW, Solar Power is 100W/m2 hence that gives 0.2km2 (or 200,000m2 of needed area for 20MW) Solar won't help you in this case

Not locally, at least. Utility-wise, it will work out.

Ok as a mechanic a few million questions: * What happens when a wheel seal goes? Do I have to remove all that ridiculous plastic on #2,3 axels?? * What happens when a tire blows? Is it going to destroy all that plastic and take out a few more tires in the process? * Why all the glass? I've spend entire days replacing windshields for a 12 or so truck shop which generally come in two (drivers and passengers), the Tesla…

I get the concern, I know a truck driver, damage occurs very often and is difficult to prevent even by the best of drivers. But perhaps bumpers are less necessary when the thing is full of sensors and stops the truck before something is hit? Doesn't prevent damage from thirds of course.

Call me a fanboy, but something tells me that the guy who built a revolutionary space program from scratch while successfully running a revolutionary auto company, probably has some ability to think things through pretty comprehensively from all angles and plan effectively for what's needed. Do you think you've just pointed out something that never occurred to him? Do you think if you could share your comments with h…

I think OP is talking about the big picture, there will always be issues like the on with the production.

What does "nuclear blast" mean? 5m to the explosion? 10km to the explosion? What warhead? 10kt, 10Mt?

I assumed it meant "nonspecifically, but impressively, tough."

Like my fist has the power of a supernova explosion?

I would say no because they currently have no sleeper cabin in their design

And I don't see where they can hang the traditional playboy calendar.

On one of those big screens of course, even that calendar has to go with the times after all.

Every refrigerated container I've seen has its own cooling unit and does not use the trucks power.

I've always wondered about this. Do they have their own fuel tank and engine to run the compressor for refrigeration?

Yes.

And they have electrical hook up point for times when they are stationary. If you think it through, the time a refridgerated container spends actually connected to the truck is not all that big. It will spend more time in a port or on a ship, or even stationary at the departure point or destination.

All of the reefers I've seen have electrical hookups to power them when on ship/land and they have their own diesel powered generators to power them whilst attached to a truck.

There a a couple main reasons they have the diesel powered generator whilst attached to the truck:

1. Efficiency of the generator (truck companies don't want to spend more on fuel)

2. The truck is often stopped with the engine off (rest periods etc)

So in the short term attaching a refridgerated container to a Tesla semi wouldn't need and change in operation. In the longer term I guess it's possible that these containers will replace generators with battery pack to remove that emmission source, but they're likely to still be built into the container for the same reason outline above.

Details for those that couldn't watch the live stream: -500 mile range on a full charge. On empty 30 min of charging will get you 400 miles. -Lower drag coefficient than a bugatti veyron -They're claiming cost per mile is less than rail for shipping goods. -2019 availability -Lane centering + other features (jack knife prevention) -1,000,000 mile guarantee ---------------- Also they surprised announced a new roadster…

> Lower drag coefficient than a bugatti veyron I LOLed at this one. Supercars want lots of downforce so they don't constantly go off the road and you die. They're not built for low Cd. A Toyota Prius has 35% lower drag coefficient than a Bugatti Veyron. It's like when the "superfruit" people go "look at this amazing berry, it has 20% more vitamin C than a lemon!" Well yeah, an orange has 70% more vitamin than a lemon…

Sounds like a "powerwall for a small town"

In the middle of the presentation, Elon mentioned that people were asking for a Pickup truck so they built a smaller version of a pickup truck. The one you linked to is that. They aren't taking orders for it.
