The trend not largely recognized and a BIG driving force for making cities ever more dense AND self sufficient is the huge polarization between USA conservatives in the country and liberals in the cities. A battery with this much polarization between charges would explode.
What we will see much more of is an oil and water separation of the mainly liberal cities from the country almost entirely driven by the cities.
Crickets - Just a gritty means to an end. No better way for cities to substantially reduce their dependency on country meat production.
Cricket consumption if you look into it will be almost 100% city driven. In 20-30 years my guess is every big city will have a large percentage of protein intake provided by insects or larvae like meal worms. Crickets were not on anybody’s radar as a viable food even just 10 years ago and now they have chirped their way into many cityzens hearts as food. Probably a combination of city center cricket companies and apartment and condo dwellers will be growing the critters. Rabbits will become energy hogs and steaks will be outlawed - in the big city. Mealworms will be only 5 years or so behind crickets. Amazing - here come the crickets.
Personally, I don’t find the idea of eating cricket protein that distasteful but just in a rare energy bar maybe. But the way it will work for city collapse is much more than candybars and energy drinks. You literally won’t be able to buy a medium rare steak anywhere in SF and similar cities unless it was hashed out of pureed cricket carcasses.
"In the twentieth century, because of improvements in transportation and food preservation as well as to the growing demand for urban hygiene, the livestock and meat-packing industries were pushed out of cities and into remote towns in North Carolina, Arkansas, and Nebraska. The cultivation of “mini-livestock” (a term popularized by Florence Dunkel, the editor of the Web site Food Insects Newsletter) offers the interesting possibility of bringing industrial-scale farming back to cities. Big Cricket Farms holds nearly six million crickets in a compact, urban setting, raising and slaughtering them without a single complaint from the next-door neighbors. According to Bachhuber, the operation is still growing: the downtown warehouse could eventually hold as many as twenty million crickets, yielding more than six tons of protein powder a month.
The supply of protein has shaped cities, from the drovers’ roads that became London’s main roads to Chicago’s stockyard-fuelled growth and the more recent transformation of New York’s meatpacking district into a fashion and dining destination. The reintroduction of mini-livestock farming and slaughter into the twenty-first-century city would undoubtedly have its own influence on the built urban environment: shrunken supply chains, revitalized warehouse districts, and in-store cricket mills. Bachhuber hopes that the ability to operate insect farms within cities might even also tempt a younger generation to enter the farming business."
There is no reason other than city self sufficiency to grow crickets for food - in the city. Its all about pulling away from the country. Studies have shown that it is much more efficient to truck in lettuce from the country from 1000 acre farms than grow it on patchy city neighborhood plots.
