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).

• Carnot limit · formula-bound · hard, applies to this route
  η ≤ 1 − T_c/T_h for any heat engine between reservoirs at T_h and T_c
• Onsager–Casimir reciprocity · constitutive-relation · listed, never decisive
  L_ij(B) = ε_i ε_j L_ji(−B): the cross-coefficients of coupled linear transport are equal up to the time-reversal parities ε of the variables and reversal of the magnetic field; L_ij = L_ji is the zero-field, even-parity case

Steps

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

   nuclear → kinetic · loss to radiative

   • for neutron-induced fission: a fissionable nuclide and an incident neutron in an energy range with non-zero fission cross-section
   • critical geometry is required only for a self-sustaining chain reaction; a moderator is reactor-design dependent

   About 200 MeV per event, almost all as fragment kinetic energy (Frisch 1939); thermalisation is a separate step.

   Nuclear fission —produces→ Temperature gradientestablishedclaim record

   kinetic → thermal · loss to radiative

   • fragment and neutron kinetic energy thermalised in the fuel; the fuel runs hotter than the coolant

   refs [2] [3]
3. 03
   Temperature gradient —drives→ Marangoni effectestablishedclaim record

   thermal → kinetic · loss to thermal

   • thermocapillary case: surface tension falls with temperature, so a temperature gradient along the interface drives flow toward the cold side

   liquid · temperature gradient required

   Marangoni effect —produces→ Fluid flowestablishedclaim record

   kinetic → kinetic

   refs [4] [5]
5. 05
   Fluid flow —drives→ Streaming potentialreplicatedclaim record

   kinetic → electrical · loss to thermal

   • the produced liquid flow passes a charged surface or through a charged channel; the charged boundary is a condition of the step
   • not something the upstream flow provides

   aqueous medium required · bulk flow required · charged surface required

   electrical → electrical

   refs [7] [8]
7. 07
   Ionic current —converts into→ Electrical workestablishedclaim record

   electrical → electrical · loss to thermal

   • electrodes exchange the ionic current for an electronic current through the external load
