In July 2024, the world's largest science project announced devastating news: another 8-year delay, another $5 billion over budget. ITER—the $20 billion international fusion reactor—won't be ready until 2039. Even its own director admits: "It's too late to solve climate change."
Yet 35 countries refuse to pull out. Why are the US, China, Russia, and the EU still pouring billions into a project that started in 2006, was supposed to finish in 2016, and is now four times over budget and 23 years behind schedule?
In this investigation, we explore the brutal truth about humanity's most controversial bet on the future:
The promise of fusion: unlimited clean energy from seawater, 10 million times more powerful than coal, with almost no radioactive waste—the holy grail of energy that could power civilization for millions of years.
The impossible engineering: creating 150 million degrees Celsius (10 times hotter than the Sun's core) while keeping magnets at minus 279 degrees just meters away—the most extreme temperature difference ever attempted.
The race against time: private companies claim they'll beat ITER to working fusion. Over 40 startups are competing. So if they can do it faster and cheaper, why do we still need a government megaproject?
The $20 billion question: Is this humanity's greatest long-term investment, or the biggest waste of money in science history? Should we focus on technology we can deploy today—wind, solar, nuclear fission—or bet on a solution that might not arrive for 60 years?
