This is pretty cool! Basically changes the thermodynamic delta required for a condensation-evaporation cycle from climatic mediation to material mediation.

What if you could eventually program the pore size? This would mean you could change the inflow/outflow balance of the reservoirs on-demand. Imagine smart clothing. Hot out -> increase pore size so the material dumps water, cold out -> pore size shrinks so the water is less likely to evaporate.

I am peeved by the "violates physics" verbiage in the article though.
