Yeah lol I always find this the funniest part of Low Tech Magazine. While they're always breathlessly moralizing, they rarely think through (or at least write about) the social ramifications of the changes they propose. They do have some interesting ideas though, such as the use of thermal cookers, and burning biomass in a rocket stove may not be the worst idea if you live in an area with a temperate climate and a dirty grid. Perhaps more practical though would be just incentivizing ordering at a restaurant, since a restaurant will be more energy efficient at preparing food than an individual will.
