19:42Now PlayingHot fusion reactors face fundamental physical limits that go beyond achieving extreme temperatures.
Magnetic confinement systems must contend with plasma instability, turbulence, and steep temperature gradients, all of which make long-term confinement difficult. In tokamak designs, even small disruptions can lead to rapid energy loss and damage to reactor walls.
The challenge of fusion is not only generating heat, but maintaining stability in an inherently unstable plasma.
