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

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

THERMOELECTRIC WASTE HEAT RECOVERY AS A RENEWABLE ENERGY SOURCE



ABSTRACT

A thermoelectric converter is a solid-state heat engine
in which the electron gas serves as the working fluid
and converts a flow of heat into electricity. It has no
moving components, is silent, totally scalable and
extremely reliable.

Introduction

Thermoelectrics revolves around modern-day
thermocouples and their application in power generation
and refrigeration. This technology is thoroughly covered
in a number ....etc

Thermoelectric coolers, also called thermoelectric modules or peltier coolers, are semiconductor-based electronic components that function as small heat pumps. On applying a low DC voltage to the thermoelectric module, heat moves through the module from one side to the other. One face of the module is therefore cooled, while the other face simultaneously heats up. This phenomenon may be reversed whereby a change in the polarity of the applied DC voltage will cause heat to be moved in the opposite direction. consequently, a thermoelectric module ....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
