Thermoelectric power generation

The basic ideas of thermoelectricity have been known for nearly two centuries, but until well after the Second World War the primary use was for temperature measurement (qv) using metallic wires. Then, upon improvements in semiconductor technology, thermoelectric power generation and refrigeration came under serious consideration. 

Taking all of the above into account, it can be shown that the efficiency, Tj, of a thermoelectric power generator, neglecting Thomson heat, is given by... 

Thermoelectric devices represent niche markets, but as economic and environmental conditions continue to change, they appear poised to advance into more common use. Thermoelectric power generators are in use in many areas, including sateUites, deep-space probes, remote-area weather stations, undersea navigational devices, military and remote-area communications, and cathodic protection.

He also made a note of future water issues that may need to be addressed if hydrogen from water electrolysis is used more frequently. One hundred billion gallons of water per year will be required for the U.S. hydrogen-fuel-cell vehicle fleet. On the other hand, wind and PV consume no water during electricity production, and thermoelectric power generation utilizes only about 0.5 gallon of water for every kilowatt-hour produced. If wind and solar are aggressively installed, overall water use will decrease, said Turner.9...

The radioactive isotope 89Sr (also known by the pharmaceutical brand name Metastron ) is used as a cancer therapeutic to alleviate bone pain. 85Sr has been used in medical applications, such as radiologic imagining of bones, in minor commercial applications, such as thermoelectric power generation, as a beta-particle standard source, and in instruments that measure thickness and density of materials (Murray 1994). 

An important group of functional materials is formed by the III-V compounds, e.g. InSb, InAs, GaAs, which have found applications in electronics and in thermoelectric power generation (C. S. Roberts, 1967 Cadoff, 1967). The constitutive ele-...

Electrical conduction and heat transport are closely linked, the connection being described by three thermoelectric coefficients, the Seebeck coefficient (or thermopower), the Peltier coefficient and the Thomson coefficient, all of which have relevance to thermoelectric power generation and refrigeration. In perovskites, the most reported values are for the Seebeck coefficient. The magnitude and sign (+ or -) of the Seebeck coefficient are related to the concentration and type of mobile charge carriers present. For band-like perovskites, the magnitude of the Seebeck coefficient is proportional to the density of states, either in the conduction band, for electron transport, or the valence band for hole transport. 

The efficiency of thermoelectric power generation is the ratio of electrical power produced to the heat rate conducted through the material. The nondimensional figure of merit typically used for thermoelectric materials is... 

Natural gas is a source of energy that has undergone significant development in recent years. Currently the outlook for natural gas is extremely optimistic, as the demand for less polluting fuels, like natural gas, is growing in industry, in commerce as well as in its use for thermoelectric power generation.

On the other hand, the body temperature is another exploitable energy source. Feinaeugle et al. (2013) used a fiber-based thermoelectric power generator fabricated by evaporating thin Ni-Ag films on flexible textile substrates and they danonstrated a maximum power harvesting of 2 nW. Semiconductor nanowires exhibit promise for thermoelectric properties, but new, advanced fabrication techniques need to be developed.
