any negative criticism of a hypothetical situation is worthless. i loved it. my favorite part:



They use arguements based on efficiency and EROI to discount viable projects... Coal (now abundant) can and will be converted to diesel (as it was in WWII) if needed to supply the liquid fuels needed to keep farm equipment and heavy transport moving (EROI 5:1). It might have been more efficient to use the coal to produce electricity (EROI 20:1), but if liquid fuel shortage is needed to prevent starvation and keep trucks on the road then that is how coal will be used. Decades from now, as liquid fuels become more scarce/valuable/necessary using more exotic sources of electric energy (nuclear) to produce liquid fuel (cooking shale/tarsands/releasing hydrogen from water) may become justified if that liquid fuel remains necessary for food production and heavy transportation. A negative EROI just means you have chosen to spend more energy of an abundant type to get less energy stored in a more valuable fuel type... As long as the net EROI for the entire chain is positive the negative EROI fuel can be produced if needed.
