The Conversion of Waste Heat from Motorcycle Into Small Power Plant

The law of conservation of energy states that energy can be transformed from one form to another but can not be created nor destroyed. Since energy is also gone every time it transferred between organisms, that missing heat must go someplace. That missing energy becomes waste heat in the atmosphere. The heat which generated from the motorcycle is able to reach 579.8oC. To utilize this thermal energy we propose to design power plants from thermoelectric. Thermoelectric is a device that can transform heat energy (temperature difference) into electrical energy directly. The research concludes that the use of Peltier modules that are mounted on two-wheel motorcycle exhaust can generate the maximum voltage at 2.89 volts with a surface temperature of the heat side of Peltier modules is 579.8oC and low temperatures on the surface of the cold side of Peltier modules is 18.9oC (ΔT = 560.9oC) , after tested for 60 minutes. After being processed by the LM2952 voltage regulator, voltage will rise to 12.8 volts at charging batteries for motorcycles.
