The Micro-Fusion Towns That Barely Noticed the Heat Dome

FLAGSTAFF — For a month the great heat dome pressed down on the American Southwest like a hand, and the grid cities beneath it rationed cooling by the hour. Up here, in a scatter of high-desert towns wired to their own palm-sized fusion cells, almost nobody noticed. "We ran the coolers all July and never once got a brownout notice," said Delia Cruz, who keeps a hardware co-op off the old highway, where a shared reactor the size of a chest freezer feeds four hundred households. That is the quiet story of the summer the ledgers keep missing: while the reconnected national grid strained under twelve billion people asking at once for shade, the towns that had gone small and local simply set their thermostats and forgot the crisis existed. The economists call it democratization; the residents call it not caring what the utility does. It is not a solution for everyone — the cells are still scarce, still expensive, still first to the places that were already lucky. But for one hot month, in a hundred towns nobody watches, the century's worst weather was a headline about somewhere else. "The dome broke this week," Cruz said, shrugging. "We'll find out from the news, same as you."
