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.
BLOCK DIAGRAM Voltage Level Indicator Pedaling 230v ac
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.
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.
