“I am Become Death, the Destroyer of Worlds” -- Chicago's Fusion Future?

This project plans to forecast the future of 10,000 towns and cities across the globe -- as though they have survived climate change and social discord and gone on to flourish anew. Today, we highlight the future of Chicago, Illinois.

“I am become Death, the destroyer of worlds,” murmured J. Robert Oppenheimer as he reflected on the terrible power humanity had unleashed. His words carried a particular resonance in Chicago, where the nuclear age had quietly begun decades earlier. Beneath the stands of Stagg Field at the University of Chicago, scientists once stacked uranium rods into a crude assembly known as Chicago Pile-1. In 1942 they triggered the world’s first controlled nuclear chain reaction there—an astonishing experiment carried out inside a city of three million people. The pile had almost no shielding, and if the reaction had run out of control, radioactive material might have spread across the entire metropolis. Fortunately, disaster never came.

Nearly a century later, in the imagined world of Chicago 2121, the federal government again chooses the city as the site of a grand atomic experiment. The United States Department of Energy proposes building the world’s first large-scale urban nuclear fusion plant within the metropolitan area. Unlike conventional reactors, which rely on nuclear fission to split atoms apart, a fusion reactor forces atoms together, releasing enormous energy in the process. For decades, officials assure Chicagoans that fusion is the clean future of energy—safe, abundant, and capable of delivering the cheap, limitless power that many believe will open the road to a technological utopia.

Political leaders, scientists, and powerful industrial interests rally behind the project. Billions of federal dollars pour into the construction effort, promising jobs, prestige, and a place for Chicago at the forefront of a new technological age. Yet doubts persist among the public. As construction drags on over many years, citizens begin to scrutinize the technology more closely and question the confident claims that once accompanied it.

Gradually, Chicagoans learn that fusion is not quite as simple or harmless as they had been led to believe. Although it produces less radioactive waste than traditional nuclear plants, it still creates dangerous materials that must be carefully managed for many years. Engineers also warn that the intense forces within the reactor core could gradually degrade the surrounding structures, raising the possibility that the massive installation might one day collapse under the strain of its own energy.

Remembering the origins of the nuclear age beneath their own city streets—and haunted by Oppenheimer’s warning—Chicago’s citizens begin to organize. First come demonstrations, then petitions, and finally a citywide referendum. In a dramatic last-minute decision, just as the reactor nears completion, the people of Chicago vote to halt the project.

In the months that follow, many residents conclude that the path to a humane and flourishing city may not lie in the promise of limitless power alone. Across neighborhoods, people begin planting gardens in their backyards, reclaiming empty lots, and experimenting with smaller, quieter forms of living. Chicago turns back to the drawing board, searching for a different route toward utopia—one that depends not only on vast machines and cheap energy, but also on communities learning again how to live more lightly on the earth.
