Thermoelectric generators could be used in power plants and factories to convert waste heat into additional electrical power and in automobiles as automotive thermoelectric generators (ATGs) to increase fuel efficiency. Radioisotope thermoelectric generators use radioisotopes to generate the required temperature difference to power space probes ...
Electric heat can be accurately applied at the precise point needed in a process, at high concentration of power per unit area or volume. Electric heating devices can be built in any required size and can be located anywhere within a plant. Electric heating processes are generally clean, quiet, and do not emit much byproduct heat to the ...
The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple. [1] A thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, heat is transferred from one side to the other, creating a temperature ...
Electric power is used to provide air conditioning in hot climates, and in some places, electric power is an economically competitive energy source for building space heating. The use of electric power for pumping water ranges from individual household wells to irrigation and energy storage projects.
Cogeneration power plants use the heat produced during electricity generation for alternative purposes; being this more profitable in industries with high amounts of waste energy. [135] Thermoelectrics may find applications in such systems or in solar thermal energy generation. [135] [139]
Electric power generated from a heat source, such as burning fossil fuel-coal, oil, indirectly through devices like steam turbines The thermopower , or Seebeck coefficient, of a material, which governs its thermoelectric properties (a misnomer, as this quantity has units of voltage per unit temperature)
Heat: Energy produced by heating the junction where two unlike metals are joined. Light: Energy produced by light being absorbed by photoelectric cells, or solar power. Chemical: Energy produced by chemical reaction in a voltaic cell, such as an electric battery. Pressure: Energy produced by compressing or decompressing specific crystals.
Joule-heating or resistive-heating is used in many devices and industrial processes. The part that converts electricity into heat is called a heating element. Among the applications are: Buildings are often heated with electric heaters where grid power is available. Electric stoves and ovens use Joule heating to cook food.
