Tesla posted a new video about their secret Kato Road 4680 cell production lines a couple of days ago, and it contains a couple of technological gems I haven't seen widely mentioned elsewhere yet, so here's an attempt at listing these new disclosures.

1/

2/

The first thing is that there appear to be no human workers/operators whatsoever in the main production process.

To the left is an image of line workers handling finished cells in a traditional facility. To the right is the 100% automated conveyance system Tesla has.
3/

Here's how their 4680 cells are transported in racks of 8x8 cells: 64 cells each.

These standardized racks likely interface into automated pack production machines, made by Tesla Grohmann, or get directly integrated into the die-cast underbody (structural battery pack).
4/

There's an interesting detail in one of the frames: glimpse of a facility worker observing an industrial robot moving a rack.
5/

What is interesting is that:

✅ Cell production facilities are Class 7 clean rooms, while the worker doesn't wear the usual "bunny suit" protective gear.
✅ There's a barrier between the worker and the robot: likely separating clean-room air from unprotected air.
6/

This suggests that much - maybe all - of the Kato Road production floor is in an isolated high grade clean-room with no human presence. Even finished cells are handled in what appear to be a clean-room environment.

Only maintenance would require humans to enter this space.
7/

The internal unit of handling finished cells appears to be a group of "4" cells in a single holder. A rack would have 16 of these.
8/

This large "wall" of Tesla labeled units appears to be high volume storage for 64-cell racks - possibly QA testing and initial formation (charging) of the cell.

Cell formation is usually done by third party equipment - but Tesla clearly uses their own equipment now.
9/

At 0:20 there appears to be rare footage of the "jelly roll" (inner roll of the cell) being carefully pressed into the "can", creating much of the final cell body.
10/

At 0:26 I think we see how the top of the cells get pressed to the bottom of the cell.

The famous "tab-less" picture on the right was disclosed on Battery Day. I believe Tesla is pressing the continuous metal surface of electrodes to the can surface, creating good contact.
11/

Tesla's goal with releasing this video was clearly recruitment - as can be seen in the final frames of the video. 🙂
12/

𝐓𝐋;𝐃𝐖: this video IMO demonstrates that Tesla's Kato Road facility is a full scale cell production pilot line & factory that is far more ahead in commercializing & scaling their new cell technologies than the "R&D project" impression @elonmusk gave on Battery Day. 😉

Recently, the @CNIL issued a decision regarding the GDPR compliance of an unknown French adtech company named "Vectaury". It may seem like small fry, but the decision has potential wide-ranging impacts for Google, the IAB framework, and today's adtech. It's thread time! 👇

It's all in French, but if you're up for it you can read:
• Their blog post (lacks the most interesting details):
https://t.co/PHkDcOT1hy
• Their high-level legal decision: https://t.co/hwpiEvjodt
• The full notification: https://t.co/QQB7rfynha

I've read it so you needn't!

Vectaury was collecting geolocation data in order to create profiles (eg. people who often go to this or that type of shop) so as to power ad targeting. They operate through embedded SDKs and ad bidding, making them invisible to users.

The @CNIL notes that profiling based off of geolocation presents particular risks since it reveals people's movements and habits. As risky, the processing requires consent — this will be the heart of their assessment.

Interesting point: they justify the decision in part because of how many people COULD be targeted in this way (rather than how many have — though they note that too). Because it's on a phone, and many have phones, it is considered large-scale processing no matter what.
