Abstract

A rigorous theoretical analysis is presented to show that moisture extraction from air is possible using a nonuniform electric field. If the atmospheric moisture is extracted and accumulated in an extraction chamber, the humidity will gradually increase. When the humidity reaches 100%, any further attempt to increase the moisture enrichment in the moisture extraction chamber will result in the condensation of the water molecules, releasing their latent heat of condensation. This can be a very attractive source for pollution-free energy. A formulation is developed to calculate the percentage of moisture extraction considering all the thermodynamic limitations, like diffusion and thermal agitation of the gas molecules. A simple experiment was performed to establish the theory. Two identical chambers were used by extracting moisture from one to enrich the other. Very good agreement between the theory and experimental results was obtained.
