Exergy analysis of a thermoelectric power generator: influence of bi–tapered pin geometry on device characteristics
The thermal characteristics of bi–tapered thermoelectric generator are investigated. The influence of the dimensionless shape parameter, associated with the device pin geometric configuration, on the first– and second–law efficiencies and device output power is examined. The study is extended to include the effects of the external load parameter and the device operating temperature ratio on the ...

Projects Thermoelectric Generators in a Geothermal Field - Case Study
This is an R&D project which will build and test a new field-scale thermoelectric generator (TEG) at our Bottle Rock Power geothermal facility near Cobb, California. TEGs produce electrical energy when a strong enough temperature difference exists across the generator (a phenomenon known as the Seebeck effect). This will be the first TEG developed specifically to generate electricity from a ...

Solar powered solid oxide fuel cell with thermoelectric generator
Durable, location independent, environmental–friendly sources of energy which allow for modular, few moving parts, low operating noise, high electricity generation efficiency and compact technology are highly desirable. Solid oxide fuel cells (SOFCs) are promising for such energy system development, since they are energy efficient and, if pure hydrogen is used, have virtually no emissions of ...

Energy and exergy analysis of a double–pass thermoelectric solar air collector
Analysis of energy and exergy has been performed for a double–pass thermoelectric (TE) solar air collector. The incident solar radiation heats up the absorber plate so that a temperature difference is created between the thermoelectric modules that generate a direct current. Only a small part of the absorbed solar radiation is converted to electricity, while the rest increases the ...

How to Use the Waste Heat in Your Factory as an Energy Source
Modern factories are investing in technology to reduce their energy consumption, costs and CO2 emissions. This is not new, but the process of digitalisation and decarbonisation has accelerated to meet global energy transition and sustainability goals.In addition, the constant increase in energy costs pushes companies to become more efficient and reduce overall expenditure to stay competitive. If ...

Water’s Critical Role in the Power Generation Industry
Water and power are intimately connected in the U.S. and around the world. In 2015, electric power generation was responsible for 41% of total water withdrawals in the United States, according to the U.S. Geological Survey. Where does all that water go and what role does it play in power generation? HOW POTABLE WATER IS USED IN POWER GENERATIONELECTRICITY GENERATION Approximately 90% of ...

Thermodynamic analysis of a thermoelectric device
Thermoelectric devices are the possible candidates to generate direct electricity from the available thermal radiation as well as other heat sources. As compared with conventional power generating devices, they are more compact, longer-lived and environmental friendly. In the present study, the thermoelectric diode is considered and electronic as well as Carnot efficiency of the device are ...

Entropy generation metric for evaluating and forecasting aircraft energy management systems
A general Entropy Generation Minimisation (EGM) technique is applied to analyse the feasibility of energy recovery from aircraft avionics via thermoelectric (TE) devices. In employing this approach, a suitable control volume definition is chosen to evaluate the impact of an energy recovery system on the overall entropy generation of the aircraft over a mission. Only those systems which are ...
