Typed bounds on this route

Every limit the atlas holds for this route, as constraint records: reached through bounded_by claims on the route's own entities. Hard bounds (an upper bound or a formula) decide the thermodynamic-bound check above; benchmarks, constitutive relations and resource limits are listed and never decisive. No prose limit exists anywhere (pass 42).

Steps

1. 01
   Nuclear binding-energy difference —drives→ Nuclear fusiondemonstratedclaim record

   nuclear → kinetic · loss to radiative

   • for a power-producing D–T thermonuclear plasma: ion temperatures of order 10 keV and a sufficient density–confinement product (Lawson); these are power-balance conditions, not prerequisites for an individual fusion reaction

   plasma · above ~700 K

   Fusion reactions and target-level fusion energy release are experimentally demonstrated (target gain > 1 at NIF, 2022–2024); net electrical output from a fusion power plant is not.

   Nuclear fusion —produces→ Temperature gradientdemonstratedclaim record

   kinetic → thermal · loss to radiative

   • energetic products (neutrons, alphas) deposit their kinetic energy in a blanket or the plasma, which then runs hotter than its surroundings

   refs [2] [3]
3. 03
   Temperature gradient —drives→ Thermomagnetic (Curie-point) transitiondemonstratedclaim record

   thermal → magnetic · loss to thermal

   • a soft ferromagnet with its Curie temperature between the hot and cold reservoir temperatures (Gd ≈ 293 K)
   • the element must be cycled between the reservoirs, so a heat-switch or motion is needed

   solid · ferromagnet required · temperature gradient required
