In 1986, Lawrence Livermore National Laboratory completed the Mirror Fusion Test Facility-B (MFTF-B), a massive machine never turned on due to budget pressures, despite $350 million spent. The unique yin-yang magnet mirrors were capable of generating magnetic fields 150,000 times that of Earth. Fusion research showed promise and competition between the torus and mirror-based approaches. The Reagan administration’s decision to mothball the MFTF-B left researchers disappointed. Recent breakthroughs at the National Ignition Facility have reignited hopes for fusion with the first recorded fusion reaction with a net energy gain, using powerful lasers. Overall, fusion energy research continues to push boundaries.
