Metal oxide framework is a material capable of soaking up moisture from dry air, adsorbing the vapor on the surface of the materials spongelike structure. A modest amount of heat at a relatively low temperature will release the vapor from the sponge to be collected upon a surface chilled below the dew point. It is a low energy system to extract moisture from desert air. It is a system being fine tuned for a best material choice to maximize all aspects of performance. In damp air, perhaps a half-pint output every eight minutes.
