There are numerous ways of power generation which are mainly two sources based: renewable and nonrenewable. The conventional renewable energy based generation technologies are solar PV and wind energy generation. This invention is based on a non-conventional renewable energy generation technology known as footsteps waste energy harvesting system using hydro generators. Walking is one of the most common forms of activity performed by an individual throughout the globe by which a person losses energy in the form of vibration, sound and pressure. This waste energy (kinetic energy) can be converted into useable source of electrical energy. Few devices and systems have been used and under investigation by various researches to harvest this form of energy but unfortunately most of those devices are either expensive or inefficient. In this work a novel concept of converting kinetic energy to electrical energy through circulated fluid/liquid/water flow has been introduced for footsteps waste energy harvesting system. In order to obtain optimum performance, the system has been designed on two tiles structure suitable for installation at place where frequent human movements are available. A single unit of this system consists of two fluid/liquid/water bags connected through flow control mechanisms including unidirectional valves and mini hydro generators. It also comprises of energy storage unit or battery to store the energy. Battery charging and discharging system using a charge control circuit has been implemented. Finally, the implementation of such system can change the power generation techniques available for low powered devices.
