Generation of electricity from the water consumption in a multi-storied building

Green renewable electric power generation has been designed using the water flow from an overhead tank during regular consumption of water of domestic use. Kinetic energy of the falling water is used to rotate a micro turbine coupled with a DC generator... The generated DC power is stored in a battery. When the energy stored in the battery is sufficient an inverter is switched on to generate AC power for domestic use. Rest of the time load gets power from the normal commercial line. Potential energy of the water stored in the overhead tank is thus utilized to supplement some energy used in the form of hydro-electric Yearly recovery of energy is quite substantial.
