thermoelectric generator full seminar report

Abstract

Thermoelectric devices are being investigated as a means of improving fuel economy for diesel and gasoline vehicles through the conversion of wasted fuel energy, in the form of heat, to useable electricity. In modern engines 60 85% of fuel energy is expelled as thermal energy in the engine exhaust or radiator systems, and while much of this energy is not available to do work on a 2nd law basis, capturing a small portion of the energy that is available with thermoelectric devices can reduc ....etc

RADIOISOTOPE THERMOELECTRIC GENERATOR(RTG)

INTRODUCTION

Radioisotope Thermoelectric Generator is a electrical generator.
It uses a radioactive material as the fuel and uses the fact that radioactive materials generate heat as they decay into nonradioactive materials.
This released heat is converted in to electricity by using Seebeck effect using an array of thermocouples.
The output obtained in a RTG is a steady output voltage and its power capacity is a few 100 W.
RTG provides an un ....etc

Thermoelectric cooling uses the Peltier effect to create a heat flux between the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current. Such an instrument is also called a Peltier device, Peltier heat pump, solid state refrigerator, or thermoelectric cooler (TEC). It can be used either for heating or for cooling, although i ....etc
