Abstrak-Pembangkit listrik pikotermal matahari (PLTPM) merupakan konsep awal yang masih dalam tahap kajian. Pengujian dan perhitungan tegangan dan arus listrik dilakukan terhadap termoelektrik tunggal, sel termoelektrik terhubung seri dan sel termoeletrik terhubung paralel akibat kenaikan suhu pada sel-sel tersebut. Hasil memperlihatkan bahwa kenaikan suhu sebesar 71 o C menghasilkan tegangan keluaran 1 volt dan arus 0.1 Amper. Sesuai dengan kaedah hubungan seri dan paralel, hubungan seri mampu melipat gandakan tegangan keluaran dan hubungan paralel melipatkan gandakan arus keluaran untuk tambahan setiap satu keping sel termoelektrik. Kata Kunci : pikotermal, sel termoelektrik, seri, paralel, kenaikan suhuAbstract-A Picothermal solar power plant (PLTPM) is an original concept that is still under study. Testing and calculation of voltage and electrical current is carried on a single thermoelectric, thermoelectric cells connected in series and parallel connected thermoelectric cells due to rise in temperature in the cells. The results showed that the increase in temperature of 71 °C produces 1 volt output voltage and current of 0.1 amperes. In accordance with the principle of series and parallel connection, series connection is able to multiply the output voltage and the parallel connections double the current output for one additional thermoelectric cell chip

An autonomous heat-radiating gas heater for commercial outdoor environments has been selected as a test case for implementing cogeneration in autonomous gas heaters and stoves, permitting its installation and operation without the need of a connection to the electrical network. A thermoelectric generator (TEG) was selected for this purpose[1], designed for converting an amount of the produced heat into electrical power for auxiliary (ventilation, battery recharge) or ancillary functions (high efficiency LED illumination). The design approach, the layout and structure of the TEG are discussed, as well as the constraints for its integration in the existing gas heater. Design features and main components are examined: hot side heat collector for capturing heat from the flame; thermoelectric module (TEGM) technology and model selection; natural convection heat radiator at cold side; analysis and optimization of the thermal chain; TEG's assembly and its design as a whole. A prototype has been built and tested, its functional behavior has been modeled through multi-physics numerical simulation[2] to allow for further optimization and extrapolation of the results towards larger and/or more complex designs. A patent application has been issued jointly by the authors, covering the design hereinafter described.

Harvesting energy from previously unemployed ambient sources can play important role in saving energy and reducing the dependency to primary power sources (AC power or battery) of an electronic system. High-performance integrated circuits such as microprocessor, typically suffers from high surface temperature (in the order of 80-100°C) resulting from the high power density and limited cooling capacity of the package. In this paper, we consider the scope of harvesting thermoelectric energy from the wasted heat in a microprocessor leveraging on the temperature gradient between processor die surface and environment. First, we develop analytical model to accurately estimate the recycled energy considering the non-uniformity of temperature distribution in the die surface. Next, we analyze the effectiveness of the approach for thermoelectric generator (TEG) with different efficiencies (measured in terms of its figure of merit, ZT) under varying processor workload. Finally, we propose a possible arrangement for using the TEG on a processor and provide measurement results on the amount of harvested energy. The measurements on a Pentium III processor running at 1GHz show that we can harvest ~7mW of power from the processor for average workload using a commercial TEG..
