•These days people are burning out lot of calories
for their body fitness in health clubs
“WHY NOT WE CONVERT THESE BURNT
OUT CALORIES INTO USEFUL
ELECTRICAL POWER ????”

Aim of the project
• Producing our own electricity by pedaling an
exercise cycle.
• Saves energy which is used for charging the
batteries in conventional inverter system.
• Reduction in electricity bill.
• Provides a method for physical exercise
besides serving its main purpose.

Our Design
The whole system comprises of:
• An automobile alternator (12V ,35A ) which
when pedaled gives dc output which can be
used to charge the battery.
• An inverter circuit draws 12v dc from the
battery and converts it into 230V ac.
• A battery level indicator is incorporated to
avoid overcharging of the battery.

MECHANICAL DESIGN

Gear Mechanism
7
• Consists of a gear mechanism coupled to an
exercise cycle which helps to run the
alternator at around 3500rpm with least
effort.
• The alternator can charge the batteries by
supplying 10Amp current and 12V
continuously.
• Thus the battery can be fully charged in about
3.5hours of pedaling

The observations during test run are:With least effort, a human can pedal the alternator at 3500 rpm.
The maximum current, the alternator can deliver during pedaling is
10 Ampere.
The output voltage at alternator terminals is 13.3 V
There fore, the maximum power a human can generate while
pedaling our design is
Power generated by the alternator is 133 Watts

OUTPUT POWER OF INVERTER
In our project we are using a 230V / 12-0-12 V,5 A
transformer.
Primary voltage,V1 = 12 V
Secondary Voltage, V2 = 230 V
Primary current ,I1 = 5 A
Secondary current, I2= 0.2609 A
Output power = 230× 0.2609 = 60 Watts

ATTRACTIONS OF OUR PROJECT
•
Can be used in rural areas where electricity is out of
reach
•
Any time charging, even during power failure
•
Power Saving
•
Reduces electricity bill
•
Modified versions can be used for running house hold
applications like television and other appliances.
•
Low cost
•
Simple in construction

CONCLUSION
The above proposed project named “THE PEDAL POWERED
INVERTER” has been designed and materialized on the
objective of providing an alternative source of electricity as well
as an effective mode of physical exercise. We believe that this
project, if effectively used may be considered as an innovative
and a good solution for the energy crisis as far as a developing
nation like India is concerned.
