Oxhydroelectric Effect: Electricity from Water by Twin Electrodes
Electricity extraction from water by twin electrodes, mediated by oxygen molecules, that we call Oxhydroelectric Effect, is reported. The extremely simple components of this experimental system are: two platinum (Pt) wire electrodes, a saturated solution of potassium carbonate (K2CO3) in water (H2O) (with pH >10) as electrolyte, and a film of hydrophilic material (Nafion®). A dc power of the order of hundredths of nW was measured for days through a resistor connected to the twin Pt electrodes. The addition of a very small amount of hydrogen peroxide (H2O2) to the electrolyte (water-potassium carbonate solution with only 0.004% H2O2), as a source of oxygen, determines an immediate dc power jump, more than two orders of magnitude high, lasting for days. The Oxhydroelectric Effect opens the way to a completely new paradigm in what concern low-cost electrical energy generating systems, with a tremendously wide range of possible applications.
