The Iter project, which was supposed to revolutionize clean and cheap energy production, has hit some major setbacks and cost overruns. It's a project that involves 35 countries, including Europe, China, Russia, and the US, and it was supposed to be finished by 2020, but now it looks like it'll be delayed for a decade and won't be ready until 2039. Located in Saint-Paul-les-Durance, France, the project started in 2010 and had a budget of 6 billion dollars. But now, the costs have ballooned to 20 billion dollars and are still rising. Recent estimates say the budget could go up another 5 billion dollars, making this one of the biggest and most expensive scientific projects ever.
