“…In recent years, the growing interest in self-powered devices has led to extensive exploration of self-powered devices in fields, such as medicine, sports, and communications. Self-powered technology harvests energy from the environment, with the primary technologies encompassing solar cells, , piezoelectricity, − friction electricity, − and thermoelectric generators (TEGs). − TEGs enable the conversion of the thermal energy (difference between the body surface and ambient temperature) into electricity according to the Seebck effect. , Generally, the performance of TEGs is governed by the dimensionless thermoelectric figure of merit (zT) of the constituent thermoelectric material, zT = S 2 σ T /κ, where S is the Seebeck coefficient, σ is the electrical conductivity, κ is the thermal conductivity, T is the absolute temperature, and S 2 σ is the power factor (PF). − …”

The energy utilization rate of ships is low, and waste heat accounts for most of the energy loss of the main engine. In this work, a new method called the thermal power generation‐organic Rankine cycle cascaded cycle is suggested to recover ships waste heat in a cascade utilization way. When comparing the performances of R245fa and R1234ze as working fluids, factors such as performance simulation, environmental protection, and safety were taken into account. Based on these simulation, the organic working fluid chosen is R245fa. On the basis of the cascaded cycle, the influence of working fluid flow rates on essential performance parameters, such as power‐production cost, power output, thermal efficiency, and waste heat utilization of main engine flue gas is explored. The experimental system performs at its best for all metrics when the working fluid flow rates is 0.0403 kg/s, including power output of 483.25 W, thermal efficiency of 8.34%, power‐production cost of 0.3464 $/kWh, and waste heat utilization of main engine flue gas of 69.05%.

“…A strategy interlinking the heat collection, TEG wiring, electricity conditioning and storing, and temperature control, was proposed. Heat collection efficiency for the present system was found to be 34.16%; power generation efficiency was 0.87% and TE efficiency was measured at 2.49% [ 20 ]. Another example of a domestic thermoelectric cogeneration system, developed to simultaneously heat water and produce electricity, was shown by Jaber et al The TEGs were placed on the inner and outer walls of the tank and the pipe.…”

The typical operating range of domestic heating devices includes only heat generation. However, the availability of combined heat and power generation in microscale devices is currently becoming a more and more interesting option. This paper shows the experimental and numerical analysis of the possibility of developing a micro-cogeneration system equipped with a wood-fired heating stove and a prototype of the thermoelectric generator equipped with low-price thermoelectric modules. In the first step, mathematical modeling made it possible to analyze different configurations of the hot side of the thermoelectric generator (computational fluid dynamics was used). Next, experiments have been conducted on the prototypical test rig. The maximum power obtained during the discussed combustion process was 15.9 We when the flue gas temperature was approximately 623 K. Assuming a case, when such value of generated power occurred during the whole main phase, the energy generated would be at a level of approximately 33.1 Whe, while the heat transferred to the water would be approximately 1 078.0 Whth. In addition to the technical aspects, the economic premises of the proposed solution were analyzed. As was shown, an installation of TEG to the existing stove is economically not viable: the Simply Payback Time will be approximately 28.9–66.1 years depending on the analyzed scenario. On the other hand, the SPBT would be significantly shorter, when the installation of the stove with an integrated thermoelectric generator was considered (approximately 5.4 years). However, it should be noted that the introduction of the power generating system to a heat source can provide fully or partially network-independent operation of the hot water and heating systems.
