“…The purpose of the experimental session is to characterize the different parameters of the exhaust gas at different operating points of the engine, i.e., at different loads, torque, and rpm. Several works have been published related to the recovery of exhaust energy through thermal or pressure conversion [6,[9][10][11]13,27]. However, kinetic energy can be potentially converted into useful electrical energy for powering IoT sensors for monitoring the gas properties such as concentration of polluting species, fuel not combusted or temperature.…”

“…The exhaust gas monitoring system is a comprehensive system made of the gas sensors, data logger, data transceiver, and power system. In order to avoid issues related to replacing batteries powering the sensors and the transceiver, several ways have been reported to recover energy from the engine [6][7][8][9][10][11][12][13][14][15][16]. The scope would be to design a complete IoT system for sensing, logging and transmitting data from the exhaust gas [17] and ideally, the system should be self-powered using the energy available in the environment in which it operates.…”

The exhaust system of the light-duty diesel engine has been evaluated as a potential environment for a mechanical energy recovery system for powering an IoT (Internet of Things) remote sensor. Temperature, pressure, gas speed, mass flow rate have been measured in order to characterize the exhaust gas. At any engine point explored, thermal energy is by far the most dominant portion of the exhaust energy, followed by the pressure energy and lastly kinetic energy is the smallest fraction of the exhaust energy. A piezoelectric flexible device has been tested as a possible candidate as an energy harvester converting the kinetic energy of the exhaust gas flow, with a promising amount of electrical energy generated in the order of microjoules for an urban or extra-urban circuit.

Power generation using thermoelectric generator technology is becoming increasingly attractive solution due to the ongoing substantial improvements in material engineering, system optimization, and novel manufacturing technologies with recent advances in nanotechnology. The design and fabrication of novel thermoelectric materials is challenging because they require co-optimization of complex properties to efficiently convert thermal energy to electricity in what is known as the Seebeck effect. Computational chemistry and machine learning offer a solution toward finding optimal thermoelectric semiconductor alloys with higher figure of merit values. In this chapter, fundamental aspects and advances in thermoelectric materials for power generation are presented and discussed. A thorough modeling and numerical simulation for a case study of a TEG device application are also presented and discussed in this chapter.

“…For instance, 30-40% of the elemental gasoline fuel energy is lost as waste heat energy in the exhaust gases produced by a gasoline spark-ignition-driven engine. The waste heat discharged in the exhaust gases from a typical passenger automobile moving at a regular speed is 20-30 kW [3][4][5].…”

Numerous energy sources continuously emit large amounts of waste energy into the earth's atmosphere. Significant losses, nearly 85% of the incident light on a PV panel, are either reflected from the PV surface, accounting for up to 20%, or dissipated as heat. In this work, a novel lab-scale hybrid photovoltaic-thermal regeneration (HPVT-R) system is designed, constructed, and tested to restore some of the reflection losses in the PV system. The new HPVT-R system design permits the PV and thermal co-systems to perform autonomously while revitalizing some of the reflection losses by hybridization. Thorough testing of the HPVT-R system was performed under lab-scale indoor simulated light and outdoor solar radiation conditions in Thunder Bay, Ontario. The HPVT-R system regenerated approximately 14 % of the reflected light in these tests, transforming it into electrical power and heat. Under the solar-simulated lights, the indoor test setup regenerated around 17 mW of electric power from the reflected light accounting for slightly less than 1% of more electric power per unit PV surface area. However, the outdoor solar radiation tests rejuvenated nearly 137 mW of electric power, accounting for approximately 3% more electric power per unit PV surface area, with a conversion efficiency of nearly 7%. Regarding heat energy, the HPVT-R system regenerated approximately 34% more in indoor and outdoor performances entirely from the reflected light. This research investigates the performance aspects of the HPVT-R system operated under different working conditions.
