This thread is incomplete without a level-headed discussion about Lithium 6...a corollary to your comment...but I’m done beating my head against the wall about it here.
Our “cheap” energy, which previously came from the sun by direct radiation or indirectly through photosynthesis, whether from burning wood or oil, or from eating grass, oats, or bread, will never be topped by these alternative schemes, IMHO.
And yeah, the average cotozen usually doesn’t even know how to spell lithium, let alone be impressed by its impact.
