Giant Thermoelectric Response of Nanofluidic Systems Driven by Water Excess Enthalpy.Nanofluidic systems could in principle be used to produce electricity from waste heat, but current theoretical descriptions predict a rather poor performance as compared to thermoelectric solid materials.  Here we investigate the thermoelectric response of NaCl and NaI solutions confined between charged walls, using molecular dynamics simulations.  We compute a giant thermoelectric response, 2 orders of magnitude larger than the predictions of standard models.  Accordingly, the thermoelectric response can be boosted using surfaces with large hydrodynamic slip.  Overall, the heat harvesting performance of the model systems considered here is comparable to that of the best thermoelectric materials, and the fundamental insight provided by molecular dynamics suggests guidelines to further optimize the performance, opening the way to recycle waste heat using nanofluidic devices.
