Charlot × Hiner · microfluidic co-optimization

One fluid, three currents

A single embedded electrolyte network is coolant, power supply, and computer at once — it carries heat out, charge in, and information. The three are coupled through one flow, so pricing any of them alone is wrong. Turn the flow and the load and watch the joint cost, exergy destroyed per useful outcome, move.

Illustrative first-order model. Literature anchors: embedded cooling ≳ 1.7 kW/cm²; on-chip fluidic power ≈ 0.7 W/cm²; iontronic switching ≈ 0.2 fJ/spike.
