3. INTRODUCTION
Walking is the most common activity in human
life.
When a person walks, he loses energy to the
road.
This energy can be tapped and converted in the
usable form such as in electrical form.

4. Conventional & Non-conventional
Energy Sources
Energy produced by coal, petroleum, natural
gas etc. are called conventional sources.
 where as the sources like biomass, wind,
solar etc. are called non conventional energy
sources.

5. AN ALTERNATIVE ENERGY
SOURCE
 Footsteps are an untapped
natural resource.
 The Challenge – convert
footstep energy to electrical
energy.
 The Solution – using
piezoelectric material.

6. The utilization of waste energy of foot power
with human motion is very important for
highly populated countries.
India and China where the roads, railway
stations, temples, etc. are all over crowded and
millions of people move around the clock.
NEED OF THE SYSTEM

7. BASIC PRINCIPLE
When a pedestrian steps on the top plate of the
device, the plate will dip down slightly.
The downward movement of the plate results in
rotation of the shaft of an electrical alternator
fitted in the device.

9. MODEL OF FOOTSTEP ENERGY
GENERATION

10. SIDEWALKS = POWERPLANTS
The technology converts
kinetic energy into
electrical energy.
 The energy stored is
later used for various
purposes.
 This is suitable for
highly populated urban
areas.

11. FOOTSTEP ARRANGEMENT

12. WORKING
The pushing power is converted into electricity
The piezoelectric material is fixed at the plane.
The spring is used to return the inclined step in
same position by releasing the load.
The shaft of generator is connected to the
piezoelectric material. DC is generated.

13. APPLICATIONS

14. APPLICATION IN STREET LIGHTNING

15. ADVANTAGES
Power generation is simply walking on step.
 Power also generated by running.
No need fuel input.
This is a Non-conventional system.
Battery is used to store the generated power.

16. DISADVANTAGES
Only applicable for the particular place.
Initial cost of this arrangement is high.
Tiles used are durable but not everlasting.

17. REAL-WORLD INSTALLATIONS
 Simon Langton Grammar
School for Boys – UK
 Empire State Building -
US
 Panduit Corporation
World Headquarters – US
 Riverdale Country
School – US

18. CONCLUSION
 Smart system
 Produce 2000 watts of electricity.
 Durable
 Have a life of approx. 5 years.
