To develop a renewable and abundant energy system, an advanced mechanism of energy source is being identified to breakdown atmospheric water molecules to form green energy instead of releasing it into the atmosphere for causing diurnal temperature change. As electrostatic force has the tendency to attract the water, the employment of static electricity force-creating water tank is being considered to install at each house to trap the water molecules from the air. Then, the sunlight, the only vitality input, has been employed to facilitate the photo-electro hydrolysis process into the water tank aiming to regulate the water electrolysis (anode oxidation: 2H2O(l) = O2(g) + 4H+(aq) + 4e− eo = +1.23v; cathode reduction 2H+(aq) + 2e− = H2(g) eo = 0.00v) rapidly to form H2 energy which is benign to the environment. As water tank is an ideal electrolyte cell (eocell = eocathode − eoanode) −1.23v at 77 °F and pH 0 ([H+] = 1.0 M) at 77 °F with pH 7 ([H+] = 1.0 × 10−7 M), this electrolyte cell is being clarified as the reservoir of the free-state energy (ΔG° = −nFe°) respecting H2-generation rate. Simply, this form of H2 energy generation would be the interesting source of energy science to meet the global energy demand significantly.
