Issues concerned with the energy conversion of exothermal heterophase processes are discussed using the physico-chemical interaction between ZrO 2-Y 2 O 3 (3 mol %) nanopowder system and atmospheric moisture as an example. The electrical properties of an experimental sample are investigated upon moisture saturation in the case of a molecular-flow density gradient. A probable mechanism for the effect based on the theory of contact phenomena in semiconductors is proposed. The idea of developing chemical-electric converters fabricated from nanoscale materials with dielectric conduction is suggested.

Direct energy conversion techniques are now dominated by photovoltaics. But, this dominance will be soon challenged by the emergence of a new conversion methods, known as so called "chemovoltaic". Here we demonstrate the possibility of the electric energy generation through interactions of atmospheric moisture and ZrO 2 based nano
