See Article History. Peltier effect, the cooling of one junction and the heating of the other when electric current is maintained in a circuit of material consisting of two dissimilar conductors; the effect is even stronger in circuits containing dissimilar semiconductors.
The Peltier effect is the basis for many modern day TE refrigeration devices and the Seebeck effect is the basis for TE power generation devices (see Thermoelectric Devices: Refrigeration and Power Generations With No Moving Parts).The versatility of TE materials is illustrated in Fig. 3 which shows a diagram of a thermoelectric couple composed of an n-type (negative thermopower and electron.The Peltier effect, despite being first noticed by Jean Peltier in 1834, remained a backwater of physics for over a century. However, in the last few decades, the technology has experienced a revival, leading to its incorporation into a number of commercial systems, our thermal desorption instrumentation being one.III. Peltier Effect (1834) The reverse of the Seebeck effect is also possible: by passing a current through two junctions, you can create a temperature difference. This process was discovered in 1834 by scientist named Peltier, and thus it is called the Peltier effect. This may sound similar to Joule heating described above, but in fact it is not.
Peltier Effect With Dissimilar Metals At the junction of two dissimilar metals the energy level of conducting electrons is forced to increase or decrease. A decrease in the energy level emits thermal energy, while an increase will absorb thermal energy from its surroundings. The temperature gradient for dissimilar metals is very small.
The existence of martyrs has a profound effect on the people who know them, and on those who feel them to be symbols of grand injustices. A martyr is all it may take to radicalize a movement and to push otherwise peaceful people into violence. A martyr in the making is a man named Leonard P.
A schematic illustrating the Peltier effect between two dissimilar materials (A and B). As a current (I) flows through the junction of the two materials, heat is either absorbed or rejected depending on the direction of the current through the two materials. The Peltier effect is the basis for electronic refrigeration discussed in the text.

Peltier effect: When two dissimilar metals are joined to form two junctions, emf is generated within the circuit due to the different temperatures of the junctions of the circuit. 3. Thomson effect: When two unlike metals are joined to form junctions, the potential exists within the circuit due to temperature gradient along the entire length of the conductors within the circuit.

Peltier Modules provide voltages using nothing but the heat emitted from various sources such as wood burning, candle flames, latent heat from industries, or the heat produced from the residential areas while cooking. The temperature difference created between the hot side and the cold side.
Three witnesses, who at the trial placed Peltier at the murder scene, later recanted their statements and said that they were coerced (AIM For Freedom For Leonard Peltier). Unlike his colleagues who were tried in Iowa, Peltier was tried in Fargo, South Dakota by a jury that did not represent his peers (Linder, Famous Trials: Leonard Peltier trial, paragraph 20).
