I wonder what structural batteries means for a battery replacement if needed?

Batteries will have to be removable for recycling. Perhaps replacement for defects will be by module. Musk implied no subdivision of cells within the pack, but I'm surethe real pack will not be so simple.

Anyone have insights into C rate and energy density of the new cells? I was quite confused. C rate would seem to be much higher. But was Musk claiming higher energy density of just lower cost?

I found Musk extolling other manufacturers to get involved to be quite weird. Reveling a highly proprietary process and then saying everyone should also do it. Then he reverted to the "we make our patents publicly available b.s.

Makes total sense. He said they'll be battery constrained unless they do something about it. So they came up with an entirely new battery and manufacturing technology. The more manufacturers that produces these cells, the more cars, cybertrucks, powerwalls, and powerpacks Tesla can sell, which is ultimately good for Tesla in the long run. Remember Musk isn't trying to make Tesla super profitable or proprietary -- he's on a mission to accelerate the world's transition to sustainable energy. And this is a step in that direction.

Why is it "b.s."?

Because Tesla's primary asset is their IP which they are certainly not giving away.

Auto manufacturers agreed a long time ago not to sue each other over small patent infringements. They essentially share less important patents. Musk opening Tesla less important IP is a defensive mood to "join the club" and not face litigation.

Not to say that Musk isn't sincere about encouraging EV adaption, just that his patent sharing this isn't a saintly move. It's the correct way to play it.

Apparently it's really hard to build a car without technically violating other people IP.

I have always understood it to mean the patents are publicly available... to be licensed$$$.

Nope. Free. As long as they're used in "good faith"

Whole heartedly disagree. By definition, patents are IP. Just look at their long list of global, EV specific patents they have open sourced. These are not "small patent infringement" type patents:

But sure, some other car maker would have to write (or license) their own AP software. AP is not Tesla's primary asset.

The battery design is just a piece in the puzzle - 54% total range increase estimate
