I know that techno-fixes are not popular on TAE. Nevertheless, I thought this one might be of interest. If the promise can be fulfilled, it means that the earth can either handle a greater number of people or that fewer people need drop off as oil depletes.
Thanks for the link. I am positive about techno-fixes or should I say hopeful. Have heard somewhere that graphene is the difficulty there. I dont recall exactly where (just catching on/up). But just on the techno-savior theme I am hopeful that renewables sustainables can save remnants of the good human endevours and make humanity’s transition a little less painful, after the leeches finally drop of their host (us) that is.
