The document discusses methods for generating electricity using vehicle weight, aiming to alleviate the electricity crisis in India. Two key methods are explored: the rack-pinion mechanism and piezoelectric materials, both offering economic advantages and high efficiency. The paper concludes that these innovations could reduce dependency on traditional power sources and meet increasing energy demands.

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.

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%

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.
