• Used the pedal mechanism of sewing machine to generate power to charge portable devices
• Made the pedal work as slider crank mechanism and used a flywheel to store the energy
• Designed a gear box to increase the speed and reduce the torque and the rotational kinetic energy is converted into electrical energy using dynamo.
• Used a battery to store the electrical energy
• Determined the commercial potential of the system by using renewable energy tools and economic analysis.
