Physics vs The Line | Saudi Arabia's Impossible Megacity

Описание: On September 16, 2025, work on Saudi Arabia’s $500 billion megacity, The Line, quietly ground to a halt. 🏗️🚫

Designed to house 9 million people in a 170km mirrored wall cutting through the desert, The Line was pitched as the future of urbanism. But by early 2026, less than 2% of the project had been realized. What went wrong?

In this video, we dig past the PR renders to uncover the three hard engineering realities that doomed the project. From the physics of linear travel to the ecological nightmare of a 500-meter tall glass wall, we explain why this was less a failure of money, and more a collision with geometry itself. 📉📐

In this video, you will learn:

Why linear cities are mathematically inefficient compared to circular ones.
The massive hidden carbon cost of "zero-carbon" construction.
How the project shrank from 170km to just 2.4km.

Question for the comments: Do you think we will ever see a fully realized linear city, or is the concept fundamentally flawed? 💬
