“Heatsinks accept entropy from the fusion chambers. Heat pumps push waste energy into the ship’s plasma shells, which are already inflating to enclose Sessrúmnir’s caravan stack in a many-layered spectral shroud. The plasma is held in equilibrium by magnetic flux squeezing against the fluid pressure of the heated plasma. Tiny confetti nano-motes dance within the plasma. They respond to Sessrúmnir’s magnetic coaxing, aligning into pseudo-crystals along curling field lines. As the plasma temperature climbs, Sessrúmnir orients the flakes, silver side in, dark face out, directing radiated heat away from the ship’s hull.”
