The proposed design aims at providing a cost effective, eco-friendly, multi-functional roof which is practical to use. The main aim of this project is to extract water from air present in the surrounding area. It also performs rainwater harvesting. To save electricity the natural light from sun can be used  to brighten up by refraction and scattering of sunlight through our device. The dark detector is used to turn the lights of the system at night. This device does not require any external power, it completely works on solar power. It proves as a solution to many problems such as global warming, irregular electric supply and scanty rains.
