Abstract: The purpose of the work is to develop and create a thermoelectric power source that has a low cost and operates on solid fuel.Method.During the study, a combination of analytical, computational and experimental methods was used to develop the optimal design of a thermoelectric generator and determine the conditions of its use.The following tasks were solved in the work: to create a thermoelectric device for charging mobile gadgets using solid fuel; to investigate the functioning of the device using different types of solid fuel; to provide recommendations for its optimal use.Results.The paper describes the development and creation of a low-cost device based on a thermoelectric generator for charging mobile gadgets using solid fuel with an output voltage of 5.8 ± 0.2 V. Based on the ratio of optimal parameters in the generator, two MTG2-1.13-127T2Sthermoelectric modules based on bismuth telluride were used.The maximum temperature for their hot side is 230 °C.For effective cooling of the other side of the modules to a temperature of 50 °C, a Deepcool SK-AM209 V2 processor cooler powered by the generator itself was used.The operation of the device using different types of solid fuel was also experimentally investigated, its cost was calculated, which is within 30 US dollars, and recommendations were given regarding the optimal conditions for its use.Practical importance.The device can be used in domestic and field conditions.The main type of fuel for the device is charcoal, the time of stable burning (smoldering) of 50 g of which exceeds 90 minutes.This provides sufficient energy and power for quick charging of mobile gadgets for 1.5 hours.Scientific novelty.Similar devices available for sale outside Ukraine are expensive and therefore not in demand by Ukrainian consumers.A thermoelectric power source, which is affordable for a wide range of consumers and convenient to use both in domestic and field conditions, is an original development ready for implementation in industrial production.
