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 provi ....etc

AUTOMATIC SPEED CONTROLLER FOR FANS AND COOLERS



INTRODUCTION

This is a device to control the speed of fan and coolers automatically. The
device presented here makes the fan run at a full speed for pre determined time. This
speed is decreased to medium after some time and to slow then onwards after a period

of 8 hours, the fan or cooler is switched off.

The circuit consist of IC1 (555 Timer IC) which is used as an asta ....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
