Scientists hail ‘breakthrough’ in harnessing fusion energy

U.S. scientists say they’ve made a breakthrough in harnessing fusion energy, the process that powers the sun. We discuss what that could mean in the push for clean power with Robbie Scott, a senior plasma physicist in the Central Laser Facility’s Rutherford Appleton Laboratory; and Greg Twinney, the CEO of General Fusion, a Vancouver-based fusion company.
