Thermal electricity refers to the generation of electrical power through heat, primarily achieved by burning fossil fuels like lignite coal to produce steam that drives turbines. This process involves converting thermal energy into mechanical energy, which is then transformed into electrical energy via electromagnetic induction. The discussion highlights the relationship between the type of fuel used and the efficiency of the flame, suggesting that certain conditions can influence the flame's direction and intensity. Additionally, the conversation touches on thermoelectric effects, such as the Seebeck and Peltier effects, which relate to the generation of electricity from temperature differences in semiconductors, although the primary focus remains on traditional methods of generating thermal electricity through combustion.
