It’s not all wine and roses in terms of requiring sustained fracking, which defeats the purpose of transitioning away from fossil fuels, but the estimate is there’s enough lithium (as lithium carbonate) coming from these sites to cover 40% of domestic demand.
That last part though.
There’s a couple ways to read that, one being ‘at dosages which have been shown not to cause clinically significant side effects’. The other interpretations are more concerning, of course.
I vaguely remember reading that lithium in low doses has huge benefits with minimal to no side effects, but it’s generally not taken due to stigmatization from the downsides of people being forced to take way too much for mental illnesses in the past.
