THERMOELECTRIC POWERED CAR

INTRODUCTION • The idea behind this project is to make a Car that is powered

by thermoelectric source, i.e. to build a car that moves with temperature difference.

• This concept has not been explored earlier but a lot of research can be done in this regard.

• We will be presenting a practically running model of a car driven by a simple heat source with the help of thermoelectric generator.

CONCEPT • The world wastes a lot of heat. Between half and two-thirds of

the fuel we burn to create energy is dissipated as heat into the atmosphere. While it has been long known that waste heat can be converted into energy, the low efficiency of early thermoelectric generation systems was such that it limited the process’s usefulness.

• TEGs can take waste heat from energy generation or industrial processes and convert it into electricity. TEGs can provide electricity to a load directly when a constant heat source is available, or they can be used in combination with batteries if the heat source is not constant. A typical TEG is made of bismuth-telluride semiconductors sandwiched between two metallized ceramic plates

THERMOELECTRIC GENERATOR

PRINCLIPLE• This concept is very useful in terms that it adds up to other

renewable sources of energy and can be used in place of other non-conventional sources of energy like wind, solar, tides, geothermal heat, etc.

• This is a new concept for electricity generation using temperature difference between junctions of a peltier element to be used in our project.

• The complete Thermo Electric Generator would be based on Seebeck Effect that is reverse of peltier effect.

• The thermoelectric effect is the direct conversion of temperature differences to electric voltage

WORKING • . This system utilizes the low temperature difference between

two hot and cold junctions of peltier element to generate pollution free electricity without any moving or bulky parts using the latest technology of thermoelectric generation using peltier plates.

• when the temperature difference is maintained by heating element in one side and cooling element in other side, thermoelectric current flows through the junction and voltage is obtained at the output of TEG.
