Tesla battery supplier to resume output in China on Feb. 10
"SEOUL, Feb 7 (Reuters) - LG Chem, an electric vehicle battery supplier for Tesla Inc, said on Friday it planned to partly resume output at its facilities in China on Feb. 10, suspended since Feb. due to the coronavirus outbreak."

Tesla's Q1 international RO-RO shipments are in full swing, here's the ship positions from today:
The first European ship, Glovis Cosmos, should arrive in 1-2 days at Zeebrugge.
Thank you so much for posting this. I was literally thinking ALL NIGHT in my sleep, "Are there any ships taking cars to be delivered? How many cars are going to be delivered this quarter?"
So you answered one of my questions. Wish you had posted last night though - maybe I would have gotten twice as much sleep with half as many questions on my mind.
Huh...
I would interpret that as meaning others having the same idea currently.
Look at the new positions in SoFi and Robinhood.

There's rumors that there's now heat pump HVAC on the Model Y, and Tesla did use the 5-cycle test for the Y per the latest fuel economy datafile, so the heat pump's improved efficiency will be reflected.
Another interesting thing: given that Model Y P19 efficiency is the same as the Model 3 P18 (the 3 P19 isn't the right comparison, as the Y 19" wheels are aero wheels, and the Y has more sidewall, which can give lower rolling resistance), yet shorter range (316 derated to 315, as opposed to 332 derated to 322), Tesla's leaving about 5% of range on the table. The pack specs (350 V, 230 Ah) quoted in the EPA data file are the same, so that almost reads like Tesla's decided to leave some room at the top of the pack?
I had to give up part way through that video, I found the guest far too dull and difficult to listen to. I'm a fan of the channel, just not that video. Even if the message was largely a positive one.

Max pain 730.
Huge nest of puts at 700, huge nest of calls at 800, and a mix of both (more calls than puts) at 750.

Patent describes that it has better conductivity as a main element. So it appears that it is for use in electrical components (they show motor parts in the Patent).
Especially because they will just come out and do them at your home or office. Takes less than ten minutes (in the S, probably the same for X).

Rumor has it that cell supplier for Model 3 made in China opens facory again this Monday.
This assumes that bulls always have dry powder, aren't concerned with the percentage of investment in a single stock, and think the time is right to buy. Pretty big assumptions.
FYI, the Electrek article refers to a published patent application, not a published patent. Two different things.

That's well and good for Germans, but the majority of drivers do not average over 90 MPH. Here on the East coast I tend to average 60 MPH or less, which matches the EPA ratings pretty well. My $37,000 SR+ goes farther than the Porsche at that speed, and because it has a battery of half the size, it can also charge faster than the Taycan with a peak of 170 kW.
The title is a bit exaggerated and biased, but not really surprising. A better description would be something like "Tesla
Basically, the materials guys at Tesla played with different Al alloys chemistries (starting from certain principles, but semi-empirically) in an attempt to get the desired combo of properties, as described in the patent application:
"...the present invention relates to aluminium alloys with high strength, enhanced conductivity, and improved castability for high-performance applications including automobile parts."
They found that alloying a commercially-pure Al alloy with about 4-6 wt.% Ni gave them improved strength but retained high conductivity and also improved the castability of the material. Seems they're aiming for cast parts as opposed to wrought, whatever the reason might be -> later edit: from the patent application: "...because it is desired to form these electric vehicle parts through a casting process, wrought alloys cannot be used. Rather, it is desirable to form the parts through a casting process, such that the parts may be cast quickly and reliably..."
Further quotes: "... the alloy is cast into a product... the product is a portion of an electric motor... the portion of the electric motor is a rotor..."
By the way, before everyone gets super-excited by this: this patent application is just so that Tesla can claim ownership of this particular alloy that they developed, which has a certain set of improved properties compared to existing alloys, but it doesn't mean it's going into production. Their R&D department is probably trying many different things, and this is one possible solution to an engineering optimisation problem, but not necessarily the only one or the best (most convenient, lowest-cost, best-performance etc.) one.
Personally, I also wish people would stop expecting Tesla to start producing that full-frame one-cast-part chassis, as that's highly unlikely.

They are aiming for high-pressure (vacuum) molding, which has numerous advantages in terms of production volume, production cost and material strength.
I agree with the production volume and cost considerations, but the strength of a cast part will not be higher than that of a wrought part, which is what I was comparing it to.
Your suggested title is misleading. "Tesla patents..." isn't true because Electrek referred to a published patent application, not a granted patent. Two distinct and different things.
