Abstract Thermal energy, i.e., the electromagnetic energy in the infrared range that originates from the direct solar radiation, outgoing terrestrial radiation, waste heat from combustion of fuels, heat-emitting electrical devices, decay of
radioactive isotopes, organic putrefaction and fermentation, human body heat, and so on, constitutes a huge
energy flux circulating on the earth surface. However, most energy converters designed for the conversion of electromagnetic energy into electricity, such as photovoltaic cells, are mainly focused on using a narrow part of the
solar energy lying in the visible spectrum, while thermomechanical engines that are fueled by heat in the broad
energy range… More >
