Self-sustaining water induced energy generation is achieved when vertically aligned multi-walled carbon nanotubes (CNTs) are used as an active medium for water-induced separation of ions. The concept of using a stern double layer to induce voltage is optimised by varying the pattern on the CNTs array and varying the solution used. Using a focused laser beam setup, engineered patterning of microarray of CNTs with high precision is achieved. Further enhancement to such effect is achieved in the presence of Na+ and Cl− ions in water. In a place that is both humid and surrounded by the ocean, our findings opens the doorway to an alternative source of sustainable energy.
