Ionic thermal up-diffusion boosts energy harvesting
Phys.org -

Salinity gradient energy is recognized as a promising candidate for the substitution of traditional fossil fuels. Recently nanofluidic salinity gradient energy harvesting via ion channels or membranes has drawn increasing interest due to the advances in materials science and nanotechnology, which could offer much higher power density than the macro reverse electrodialysis systems, indicating its potential to harvest the blue energy (about 1.4-2.6 TW) released by mixing seawater and river water...
