Episode notes
Magnetic Mirror Reactor Design
- Rialta Fusion focuses on a magnetic mirror reactor design that confines plasma in a symmetrical bottle using powerful magnets.
- This method may allow scalable fusion power plants by adding more middle sections with weaker magnets to save costs.
Early Magnetic Field Record
- Rialta set a record in plasma magnetic field confinement just two weeks after activating their magnets last summer.
- This early milestone shows their progress toward achieving sustained fusion reactions.
Fusion Cost Competitiveness Goal
- Rialta aims to produce fusion power initially at $100 per megawatt-hour and reduce costs to $40 over time.
- This competes with natural gas plants, which cost $45 to $105 per megawatt-hour to build and operate.
