Back to TSLA
I was on an early tour. A few things that became immediately clear were that each new section (module)of the building built for cell manufacturing were individual machines in and of themselves. The first unit is already doing test runs and they already achieved large efficiency gains. We were shown examples ranging from an 80% reduction in electricity requirement for the ovens, recovery and reuse of nearly all solvent components to simple things like the use of reusable trays for,the battery aging process as opposed to the present disposable cardboard ones.
The brilliance IMO lies in the modularity of the design that allows both companies to limit risk as capacity can be added as needed and if one breaks it doesn't kill the whole thing. Each one "floats" by itself, so in the event of an earthquake or similar event the rest keep going. Also, iterations and improvements can be and already are being applied in this modular sense (no shutting down the whole line for improvements). We were shown that the factory is being designed built and modified vis CAD same as Boeing is building the 787, so no very little waste of time "testing" fits and improvements are digitally incorporated. This is being set up to be inherently scalable and easy to copy in different locations.
The "Tesla side was all about assembly of power packs for TE there were no signs of auto packs that I saw yet. The assembly involved a lot of robotics but had a significant amount of hand work still happening. The process is clearly in iterative stages and appears to be headed to nearly full automation right down to autonomous inventory bots a few of which were wandering around one of which greeted our tour by approaching us and saying "welcome to Tesla" and continuing on its mission. The workers were on an evening shift, many devoted to actual production, many building the machine right down to putting together and stocking the break areas. One sorta funny note was that the golf carts currently being use still are LA batteries, but I was assured by the employee that asked that the Li packs were close at hand, other priorities more important now...don't ya know. Which brings up order of priorities, there are very clear ones that are being pursued with great clarity, purpose and from what was demonstrated, the best possible order as well.
While there is a clear delineation of the Panasonic section we met and spoke with Tesla engineers and saw many Panasonic employees who, when greeted with "good evening ", did not answer in english. The tours were small groups (one giude in the back one in front to be sure everyone stayed where they were supposed to) managed by 2 guides per tour reading from a script and enhanced by short talks with Q&A in each section. There were clear limits as to how deeply the question would be answered but everyone shared all that they could. While one could quibble on minor details as far as factory tours go, it was entirely adequate with respect to control and safety.
The summary is that this was a clear demonstration that Tesla/Panasonic are deeply cooperating and integrated in a way that is very unique. The result is a flexible, iterative,scalable,risk limiting process that is allowing for massive gains in both the tech of the widget as well as that machine that makes it. They are executing on a process that will end in supporting the market cap value that AJ and others have discussed. This is clearly lossed on the majority of analysis that has been done. There is much to accomplish here but the scale this operation is massive and will allow both Tesla and Panasonic to,accomplish it while managing risk as well.
Fire away!
