Mizu is a salt water powered lamp aiming for an alternative to unstable electric grids or kerosene lanterns for rural communities within oceanic islands.
Many communities across the oceanic islands of south asia lack access to stable electricity. Kerosene lanterns instead have been relied on for a source of lighting but with it comes environmental, human and fire hazards
Mizu instead can be activated by the abundant ocean water sorrounding these communities or with a simple tablesalt-water solution.
Like a living organism, Mizu requires life giving water to come alive. Mizu functions based on a water activated galvanic cell.
Consisting of a zinc rod, serving as the cathode, and copper wire as the anode, this battery cell produces up to 1.5 volts when activated by salt water through a spontaneous redox reaction. A full glass of water would run the lamp for up to 2 hours.
