European battery makers power up for a green recovery

Now, China hosts 80 percent of the world’s lithium-ion cell production – the type of battery expected to power the fast-growing EV industry – and most of the capacity coming online in Europe over the next five years belongs to Asian firms.

But some European startups concede they cannot catch up with the large-scale, low-cost Asian incumbents.

Researchers have already identified 13 European battery projects that could be eligible for EU support

Heh, interesting. I guess maybe we'll be seeing different designs now?

Needs WAY more data points... given that large wind generators run at roughly 10rpm you don't really get a black-white-flicker effect going that would explain a benefit.

It shows a difference in color to the background and makes the other blades more noticeable?

Well in that case you should paint all blades black, not just one.

Maybe.

Sorry, I had to.
