Most speculative potential applications

[Todo: fill this topic skeleton]

Types of fusion

pursuable:

  • envirounmentally friendly
  • low cost
  • relatively small and lightweight

Magnetic enclosure

  • reduction of weight
  • limit for magnetic fields unclear (severe)

Inertial fusion

  • macroscopic vibration damping
  • neutral particle carriage acceleration
  • highly symmetric enclosement (thermal and quantum mechanical uncertainty)
  • low reflectivity of hydrogen - minimal isolating plasma shell thickness (severe!)
  • fast cavity cleanout
  • fast radiation seals
  • carriage particle accelerators

General notes

  • Thermal throughput bottleneck thermal energy transmission
  • self repair of thermal and radiation damage
  • isotope sorting (e.g. tuning fork method) & closed loop nuclear waste recycling
  • usage for spacecraft propulsion possible? - earth or space only?
  • Implications of Liouville's theorem or "why nuclear mechanosynthesis don't work" - detour over thermal step unavoidable
  • surface power/(heat flor) density limit - capsule based thermal energy transport (asymmetric figure eight loop in tokamaks?) may move it further down to more tacklable values.
  • consistent high temperature stable designs SiC (H-passivation?)
