Can We Make a Star on Earth? (S46E04)

Title: Can We Create a Star on Earth? Plot: Professor Brian Cox embarks on a worldwide exploration to uncover the energy of tomorrow: nuclear fusion, the same process that powers the sun and all stars across the universe. Despite decades of research, achieving even a single watt of fusion energy for the grid remains elusive. Returning to Horizon, Brian investigates the reasons behind this challenge. With exclusive access to groundbreaking fusion projects, he visits a high-security fusion bomb testing site in the USA and tours the planet's most powerful laser facility. In South Korea, he ventures into the K-Star reactor, the first super-cooled, superconducting fusion reactor, where the future of fusion research hangs in the balance.
