POWER GENERATION THROUGHFOOT STEPS

> For an alternative method to generate electricity there are number of methods by which electricity can be produced.

> Out of such methods, foot step energy generation can be an effective method to generate electricity.

INTRODUCTION:

> Dynamo: A dynamo, originally another name

for an electrical generator, i.e, a generator that produces direct current with the use of a commutator.

COMPONENTS REQUIRED:

> Rack and pinion system: A rack and pinion is a type of linear actuator that comprises a pair of gears which Convert rotational motion into linear motion.

> Rotary Converter Development:

Used to develop complex multi-field single-rotor devices with two or more commutators.These were known as a rotary converter.

COMPONENTS REQUIRED:

WORKING:

>> When a human steps on the device due to his/her body weight the iron platemoves downwards and drives the crank shaft which further drives the gear arrangements; which further drivesthe another crank shaft.

>> This crank shaft then moves the magnet in “to and fro” motion into a coil.

DESIGN REQUIREMENTS:

ADVANTAGES:

To store the electricity in battery.

It can be use at any time when it necessary.

Easy construction.

Less number of parts required.

Electricity can used for many purposes.

In street light.

In LED light for specific purposes.

In air circulation system for room by the small fans.

For used in security alarm.

APPLICATIONS:

FUTURE ASPECTS :

> > we can use this principal in the speed breakers at high ways , where the vehicles rush too much, thus increase input torque and ultimate output of generator.

> > If we use this project at very busy stairs , then we produce efficient useful electrical energy for large purposes .
