Episode notes
Fusion Energy's Potential
- Fusion energy offers a clean, low-cost alternative to current methods.
- It eliminates greenhouse gas emissions and long-term nuclear waste.
Fusion vs. Fission
- Stars use fusion, combining light elements like hydrogen to form heavier ones like helium, releasing energy.
- This differs from fission in nuclear plants, which splits heavy atoms and produces waste.
Fusion Challenges on Earth
- The sun uses gravity to force atoms together for fusion.
- On Earth, alternative methods, like lasers at the National Ignition Facility, are explored.
