Thermal depolymerization will require refineries, of a sort – together with the attendant cancer-causing leaks/byproducts. And there will be the usual NIMBY-ism about their siteing. Maybe they could convert existing refineries or ship them off to the third world, in which bribes and repression will take care of objections.
Something is wrong with depolymerization, perhaps politically because we don’t have it en masse today. Plans about using animal wastes were made many years ago and the synthetic fuel technology of Nazi Germany is 70 years old. You would think that with a mostly free fuel source and automation ( instead of WW2 slaves) that the economics would work out. I can only hope that LENR is truly decentralized as to its production – otherwise the stagnation will never end. I think there is enough evidence being spilled out about Saudi intentions currently that reveals how powerful these repressive international forces have been. The alternative energy plans of the Carter Administration were most of 40 years ago and they successfully stopped them.
