Human has needed and used energy at an increased rate for their various uses. As a result, huge amount of energy is exhausted and lost. Our objective is to harvest energy from the vehicle with or without load using mechanical gear system and to increase the efficiency level of the energy. The gear system will make the generator rotate, thus producing energy. This work is a real-time work as lot of vehicles moving daily will cross over the setup, generating efficient amount of electrical energy. It is an eco-friendly system as it doesn’t harms anything. It is a conventional power generation system when compared to existing systems. The work deals with the design of the model in real-time of the energy harvester using gear arrangements and increase in efficiency level of energy. The most challenging part in this assignment is the material that is to be used as top plate assembly, such that it can absorb heavy loads like buses, trucks with water tanks etc. Below the plate there are springs in which deformation will take place. The gear assembly is connected to the bottom of the spring through its teeth. When the spring gets deformed due to load, the gear assembly will be rotated which in turn will rotate the generator as it is coupled to the gear assembly. So energy will be produced. To increase its efficiency, gear assembly consisting of different sizes of gears, is used to increase the rotation of the generator which will produce more electrical energy. Generally, the output will be AC (alternating current), so AC to DC (direct current) converter is used. Amplifiers can also be used to make the energy more efficient and store it in battery for further application.
