3. Introduction:
 Is anyone happy with current situation of
electricity in India?
 A step has been taken which will reduce the
crises of electricity . For this the of use the
road are considered to generate power?
 So, electricity can be generated using
vehicle’s weight such as potential energy as
input.
 In this method in general potential energy is
converted into electrical energy.

4. OBJECTIVE:
 The objective for doing this step is to reduce
the crises of electricity. why we only depend
upon any thermal power plant ,or hydro power
plants etc.
 To generate power at low cost.
 As per 1megawatt generation, it impose Rs 10
million but from other source such as hydro
and thermal ,the cost is 8 times higher.

5. Methods for operation :
 In general Simple energy conversion from
Mechanical to Electrical is carried out.
 To generate electricity using the vehicle
weight (potential energy) as input
 Here two methods are considered which
has simple mechanisms
I. Rack- Pinion mechanism
II. Piezoelectric effect

6. Rack- Pinion mechanism
Terminology :
 Gear – it is used to transform rotational enegy
to other output gear.
 Sprocket – it transfer rotary motion between
two shaft.
 flywheel – it is used to store rotational energy.
when there is requirement, it release the stored
energy.
 rack and pinion – it is used to transform
between rotary motion and translatary.

7. Final arrangement:

8. Construction of generator:
 Initial experiments- DC motor as Generator
 How is electricity generated?
 Basic principle of generation of electricity.

9. Results:
 When 100 vehicles of each 1000 kg weight
passes for one minute, by this process we can
generate 1kw of energy.
 Maximum gear losses– 3 to 5%
 Efficiency up to 95-96%
9

10. Advantage :
 Non polluting source of energy.
 Less installation and maintenance cost.
 Very economical and easy to install.
 It can be designed for heavy vehicles so
that more electricity can be generated.
10

11. Drawback :
 Selecting suitable generator.
 Selection of springs.
 For lighter load it is not efficient.
 extra cost on conversion of D.C to A.C
i.e. first storing in dc battery then invert to
ac as per demand.
 Achieving proper balance of speed and
torque.

12. using Piezoelectric materials
 The word piezo is derived from a Greek
word piezien which means squeeze or
press.
 when a mechanical stress is applied to
material (crystal or some ceramics ) by
the property of piezoelectricity, it
produces a potential difference across it.
12

13. Principle:-
 When mechanical stress is applied to a
crystal ,the potential difference is
developed across it .
 The potential difference that is generated
across the terminal of crystal will be used
for the charging of battery.
13

14. Results:-
The output voltage is directly proportional
to the applied mechanical stress i.e. in
general weight of vehicle.
 analytical investigation gives that when a
1c.m^3 of piezo crystal on which 2KN of
load is applied , the output voltage will be
about 12.5KV.
Efficiency is 65-75%
It is demonstrated that a 40MAH battery
can be charged within a half an hour.
14

15. Advantage:-
 Very light weight and small in size.
 Free from pollution
 Ultra low noise
 Cost effective it is so because the cost of
one crystal of (50*35*2)mm is RS 24-25.
 Wide temperature range.
15

16. Drawback
 It can sustain maximum up to 30Mpa of
applied pressure after which it may
break.
 It is not for bulky loaded vehicle.
 It generates low power.
16

17. Future scope :
 Such can be designed for heavy
vehicles, thus increasing input stress and
ultimately more output voltage .
 More suitable and compact mechanisms
to enhance efficiency.
 it can be used in every car parking ,
footstep , in shoes, bus stand and many
more places etc.
17

18. Conclusion:-
 The existing source of energy such as
coal, oil etc. is not sufficient for ever
increasing the demand of energy.
 The crises of electricity will be somehow
reduced and dependency on power
plants also diminished.
 This is one path of exploring the possibility
of energy.
