As the city grew, simple diffusion wasn't fast enough. Elias had to implement that would make a textbook blush. He designed "Membrane Trees"—synthetic structures that utilized forced convection . Huge fans accelerated the airflow, reducing the "boundary layer"—that stagnant film of air that slows down molecular movement.
"It’s all about the ," he muttered. The city’s air was thick with carbon pollutants—a high-concentration "source." Inside the Lung, Elias had created a "sink"—a series of proprietary liquid membranes with near-zero carbon levels. Because of Fick’s Law , the carbon molecules had no choice but to migrate across the boundary, desperately trying to find equilibrium.

At the center of the city stood the "Atmospheric Lung," a massive industrial spire designed by Dr. Elias Thorne. Elias spent his days obsessed with , the silent engine of the universe. To the public, the Lung was magic; to Elias, it was a masterpiece of molecular diffusion and convective transport . The Principle of the Gradient As the city grew, simple diffusion wasn't fast enough
