Summary: Bad Ideas in Fusion
This bonus episode skewers a range of fusion concepts that persist despite glaring physical or engineering flaws. Highlights include:
- Misapplied Analogies: Designs that borrow from unrelated physics (e.g. planetary cores, lightning bolts) without rigorous modeling.
- Overlooked Loss Channels: Concepts that ignore bremsstrahlung, ion losses, or material degradation in pursuit of aesthetic plasma shapes.
- Tritium Blind Spots: Proposals that assume tritium availability or ignore its handling and breeding challenges.
- Stability Denial: Architectures that hand-wave away magnetic or electrostatic instabilities with vague “self-organizing” claims.
- Marketing vs. Physics: A recurring theme is the mismatch between flashy demos and the sober demands of the Lawson criterion.
The tone is unapologetically skeptical—calling out fusion ideas that are more wishful than workable.
