Prepare to Be Amazed: The World's Most Expensive Construction Marvels Revealed
15. ITER
Place: France
Total Expense: $26.91 Billion
Projected Completion Year: 2025 (Phase 1)
In France, a significant international project is underway, with a total projected cost of $26.91 billion. This ambitious endeavor is backed by seven of the thirty-seven member nations involved, including the European Union, China, India, Russia, South Korea, and the United States.
The project aims to enhance global collaboration and address pressing challenges through innovative solutions. With the first phase set for completion in 2025, it represents a monumental effort in international cooperation and investment in infrastructure.
In conclusion, this initiative not only highlights France's role as a central player in global development but also underscores the importance of collaborative funding and shared goals among nations. As the project progresses, it is expected to pave the way for advancements that benefit multiple sectors and foster international relations.

The International Thermonuclear Experimental Reactor (ITER) is poised to become the largest fusion reactor in the world, although the completion of its first phase is not expected before 2025. This groundbreaking project aims to advance our understanding of nuclear fusion as a viable energy source.
At the heart of ITER's design is a double-walled steel container known as a "vacuum vessel." This innovative vessel will utilize powerful magnetic fields to confine plasma, creating the conditions necessary for fusion to occur. Remarkably, the vacuum vessel being constructed for ITER will be twice the size and sixteen times heavier than previous fusion vessels, highlighting the ambitious scale of this endeavor.
In conclusion, ITER represents a significant leap forward in fusion research and energy technology. As it progresses toward completion, it holds the potential to revolutionize the way we harness energy, offering a cleaner and more sustainable alternative to traditional power sources.
