A typical thermoelectric module is shown left. The module consists of pairs of "p-type" and "n-type" semiconductor thermo elements forming thermocouples which are connected electrically in series and thermally in parallel.
 * In Cooling Mode: An electrical DC voltage is supplied to the module. Heat is then pumped from one side to the other (Peltier Effect). The result is that one side of the module becomes cold in an insulated environment. The other side becomes hot which then requires a cooling system to maintain the DT (Delta Temperature). The better the cooling system, the lower the cold side temperature. Bi2Te3 is the foundation material of all thermoelectric generator modules and thermoelectric cooling materials. There are others materials but they are extremely difficult to find commercially.
 * In Generating Mode: A temperature gradient is maintained across the module called DT (Delta Temperature). A portion of the heat flux passing through the module is converted into electrical power (Seebeck Effect). The rest of the heat is taken away by a cooling system. Seebeck Thermoelectric power modules are engineered with specific features that allow them to survive large temperature stresses and differentials. Peltier modules or cooling modules have none of these features making them inappropriate for thermoelectric power generation!

Best to least effective thermoelectric TEG power cooling methods:
- Static liquid (pot of water)!!
- Heat sink with air flow. (FAN)
- Heat sink natural convection. Least effective
