Toyota president Koji Sato also admitted that production volumes of solid-state batteries were likely to be small when the company rolls them out in electric vehicles as early as 2027. “I think the most important thing at the moment is to put out [the solid-state batteries] into the world and we will consider expansion in volume from there,” he said.

SOOOOO not really close.. another press release hyping this up. How small is SMALL? Hundreds?

They clearly are still having trouble scaling production of this technology. It has EXISTED for some time but isn't of use to cars if they can't make hundreds of thousands of them.

they're using the promise of better batteries to make people reconsider buying full electric vehicles now. I expect it to be exactly like fusion, always a few years away.

Commercial fusion is not a few years away, and I've never seen the claim apart from deranged individuals on Twitter. If everything goes to plan, commercial fusion won't be here for a few decades.

What the claim may have been is experimental fusion, which does exist right now, we have generated power using fusion, and we even made more power than we put into it recently. It's moving, but it's slow, as planned for the last few decades.

And even that "more power than we put into it" comes with a big asterisk. The power being output by the laser is smaller than the power being output by fusion. Big lasers tend to be grossly inefficient things. We'll need at least 10 times the output in order to generate enough to power the laser. That's not even considering the power usage of the facility around it.

So, yeah, we're at least a few years away from enough power for the laser to sustain itself, at least a few more to be able to run the facility and still have net power, and then at least a decade after that to get to commercialization.

Not even a press release, but an FT post. Which is worth less than a press release somehow.
