I was always a skeptic when it came to global warming.
Still not sure - but ask most people in the world if they're experiencing more extreme weather recently and I suspect the answer will be resounding.
So what's the best play for the eventual global abundance of energy storage (mobile & stationary)?
It aint Hydrogen (cuz you need energy to make it) - so it's gotta be Lithium (at least for the next 30 years).
Now ask - are there better investment opportunities than GXY for taking Lithium out of its natural habitat? is not whether there will be this or that gvt in Argentina....
If there is something better - please let me know.
