Abstract
A method for producing electrical energy. An electrolyte solution having a first concentration Cof a solute is placed in a first vessel having an electrode arranged so the electrode is contacted with the electrolyte solution of concentration C. An electrolyte solution having a concentration Cof the same solute is placed in a second vessel having an electrode arranged so the electrode comes in contact with the electrolyte solution of concentration C, the concentration Cbeing lower than the concentration C. The first and the second vessels are separated by a membrane, the membrane having at least one nanochannel arranged to allow diffusion of the electrolyte solution from the first vessel to the second vessel through the at least one nanochannel. An inner surface of the at least one nanochannel is formed of at least one titanium oxide. Electrical energy generated by a potential difference existing between the electrodes is captured using a device having the first and second vessels.
