US gave vanadium battery to China

Meh.

I've built a VRB in our labs. It isn't rocket science, you can get all the engineering information on the internet.

The main problem is getting the ion exchange membranes that separate the V2+/V3+ electrolyte from the V4+/V5+ side.
DuPont make such a membrane but is 3x the price of Chinese ones, and not better.

They are even building these VRBs in Australia and South Africa.

Good technology though, far superior to LiB for grid storage

Umm Africa is not America and are you sure of your lineage?

Rainbow can be pretty confident of his lineage. Why did you even mention Ardipithecus ramidus? No remains of them have been found outside Africa.
We are all evolved from Homo Erectus, which lived in Southern Africa, my cousin.
Right on, cuz. :tup:

We just don't appreciate link dumping. Make an effort.

I think that it's useful to include perhaps the first paragraph of a linked article, which may be enough at times, or may stimulate one to click on the link...
