The main objective of this project is to utilize the human power to produce electrical energy. The basic principle of this project is to convert Human Mechanical Energy into Electrical Energy using a DC Generator. The Input Low Speed- High Torque Human Powered Pedal Energy is transmitted as well as converted into an Output High Speed Rotary Motion of the DC Generator in order to produce Electricity. For power transmission purpose, a Chain- Sprocket assembly as well as a Belt – Pulley Drive is used to efficiently transmit power, speed and torque throughout the system.
The system consists of a Bicycle, Dynamo, Belt drive and other support accessories to demonstrate the application.

People use bicycles as the main medium of transportation in villages. In India, many of the villages are still without electricity and most of them use bicycle as their medium of transportation. In such places, our system will be of great help. Charging of the battery can be done by a layman by just connecting the circuit to the output of the dynamo which is connected to the bicycle.

Delay circuits are used to protect elelctronic circuits from abrubt change in the power. These circuits introduce some finite delay before the device gets turn on .Most simple way to implement these circuits is by using capacitors. In this circuit we can see that if we turn on the DC power by closing the switch S1, both the capacitors start charging .
To drive large number of LEDs for lighting purpose we need transistors of high power. Darlington pair of transistor is commonly used to improve the power performance of general purpose transistors(like BC547). We can see from the circuit diagram , two transistors are connected in such a way to represent a single transistor. The LDR(light dependent resistor ) is also there .
MOSFETs are also transistors hence their characteristics are very much similar to BJT. Here we are using power MOSFET hence it is capable of handling more power. Motors generally consume more power to operate hence we are using POWER MOSFET here.
the main concept is to trap the momentum of the train using a spring suspension system which converts the kinetic energy to potential energy and stores in it and later, transferring that energy to a rack and pinion gear arrangement. The gear assembly is connected to a dc generator which produces electrical power.
Simple mechanical and electrical components are used and assembled together to produce maximum efficiency from the system by reducing power losses. The overall assembly is placed over a rigid steel frame and components like springs, hinges, rack and pinion, spur gears are used to demonstrate the application of the system.
