“…The maximum power obtained was about 3.4W. Lertsatitthanakorn replicated the same experiment with a commercial TE module made of bismuth telluride based materials to the stove's side wall, thereby creating a TE generator system that utilizes a proportion of the stove's waste heat, while also using heat pipes at the cold side to maintain a temperature difference across the module (Lertsatitthanakorn, 2007). The results show that the system generates a power output of approximately 2.4W when the temperature difference is 150°C.…”

Charcoal stoves have widespread use among the poorer households and outdoor food vendors in Nigeria. In order to improve the efficiency of charcoal stoves, various researches have tried integrating a thermoelectric module in the charcoal stove. The researches, however did not exploit the performance of the thermoelectric modules at different ambient temperatures. To evaluate the performance of thermoelectric integrated charcoal stoves in the sub-Saharan Africa, a self-powered, forced air induced thermoelectric charcoal stove experiment was carried out at five different ambient temperatures of 36ºC, 33ºC, 32ºC, 30ºC and 29ºC and an average fuel hotbed temperature of 1023.75ºC. The thermoelectric charcoal stove generated a maximum voltage of 5.25V at an ambient temperature of 29ºC. The least maximum voltage was generated at the highest ambient temperature of 36ºC. It was observed that the maximum voltage increased with decreasing ambient temperature, this could be attributed to the ambient air being used to cool the thermoelectric generator. Therefore, it could be said that the performance of a forced draft thermoelectric charcoal stove increases with decrease in ambient temperature.

The thermoelectric (TE) solar air collector, sometimes known as the hybrid solar collector, generates both thermal and electrical energies simultaneously. A double pass TE solar air collector has been developed and tested. The TE solar collector was composed of transparent glass, air gap, an absorber plate, thermoelectric modules and rectangular fin heat sink. The incident solar radiation heats up the absorber plate so that a temperature difference is created between the thermoelectric modules that generate a direct current. Only a small part of the absorbed solar radiation is converted to electricity, while the rest increases the temperature of the absorber plate.The ambient air flows through the heat sink located in the lower channel to gain heat.The heated air then flows to the upper channel where it receives additional heating from the absorber plate. Improvements to the thermal and overall efficiencies of the system can be achieved by the use of the double pass collector system and TE 2 technology. Results show that the thermal efficiency increases as the air flow rate increases. Meanwhile, the electrical power output and the conversion efficiency depended on the temperature difference between the hot and cold side of the TE modules. At a temperature difference of 22.8°C, the unit achieved a power output of 2.13 W and the conversion efficiency of 6.17%. Therefore, the proposed TE solar collector concept is anticipated to contribute to wider applications of the TE hybrid systems due to the increased overall efficiency.

“…The technology was subsequently redesigned with an estimated cost of 170 USD in high volumes. Lertsatitthanakorn (Lertsatitthanakorn, 2007) investigated a TEG-stove system under laboratory conditions and was able to generate a just under 2.5 Watts, though no charge control circuitry and associated battery charging capacity was developed or tested. Although no field trial tests were performed, Lertsatitthanakorn estimated a payback period, compared with the equivalent of battery use, of less than one year.…”

A novel off-grid electricity-producing device has been designed for integration with biomass-fuelled improved cooking stoves commonly in use in the developing world. The device operates on the thermoelectric principle whereby small amounts of electricity can be produced in response to a temperature difference across a thermoelectric generator, or TEG. The energy produced by the integrated generator can be used for direct charging or stored in a rechargeable lithium-ironphosphate (LiFePo4) battery. The generator is equipped with a standard USB output which allows the user to charge a variety of 5 Volt appliances. Five technology demonstrator electricity generating stoves have been integrated with locally produced clay cooking stoves in the Balaka district of Malawi, Africa. This study details the results from an 80-day field trial of the devices. The data reveals that the stoves are in use for a greater time than was anticipated. The data also indicates that the generators perform adequately in the field and provide the user with the ability to charge LED lights and mobile phones from the generator stoves every day if necessary.
