In this paper, a model is proposed to harness solar energy for generation of oxygen and light. The solar panels convert daylight into electricity, which is used for decomposition of waste water into oxygen and hydrogen. Oxygen is released in the air to breathe and hydrogen is stored as fuel. Light Emitting Diode (LED) lights, driven from the generated electricity are used to radiate light during night. The automation and control for the processes is provided by an integrated Peripheral Interface Controller (PIC). This paper is intended to provide a model, which can be implemented to meet oxygen requirements and lighting demands of the cities in an eco-friendly manner. The paper also discusses the challenges to proposed technology and provides suggestions to overcome them
