Major Project Thermoelectric generator
Mahakal Institute of Science & Technology, Ujjain
Aim
• To design a project that can be used to utilize the waste heat energy of the car engine into electricity for multiple use in automobiles.
• This equipment should be economical, easy to implement and does not produce any burden on car efficiency or engine efficiency.

What is TEG?
• Devices that converts temperature difference into electrical energy.
• Basic principle- “Seebeck Effect” (power generation).• Peltier Effect (heating and cooling purposes).
