Introduction: Thermoelectric Generator Project

The Thermoelectric Generator is an experimental kit which demonstrates the direct conversion of heat into electrical energy using the Seebeck effect.The key component is the Peltier module that will be sandwiched between the two metal cans. As long as there is a substantial temperature differential between the two sides of the Peltier element, sufficient electricity will be generated to power the electric motor to turn the propeller.

Step 1: Step 1:

Kit contents include:

(2) Metal Cans
23" Tie Strap
Thermal Grease
4" Propeller
DC Motor Round
Thermoelectric Generator
10" Velcro Hook & Loop Strips (must be cut to size)

You will also need:
Scissors
Hot & Cold Water

Step 2:

Begin by placing the cans face to face (notice yellow labels). Center the thermoelectric generator on one of the cans so that you can position and stick the hook & look strips to the cans.

Step 3:

Apply thermal grease like pictured so that when you sandwich the thermoelectric generator between the two cans, it will have thermal grease on both sides.

Step 4:

Step 5:

Connect the propeller to the motor shaft.

Step 6:

Cut a small piece of the hook strip to place on the side (opposite side of thermoelectric generator) of the "COLD" can. Cut another small piece of the loop strip to place behind the motor.

Step 7:

Remove the motor with propeller so that you can put the tie strap around the two cans to secure them with less difficulty.

Step 8:

Connect black motor wire with black thermoelectric generator wire. Connect red motor wire with red thermoelectric generator wire.

Step 9:

Pour in your cold water to fill up 75% of the "Cold" can and then pour hot water to fill up 75% of the "Hot" can.

Step 10:

Since the thermoelectric generator works from temperature differentials, using a glass alcohol thermometer, you can measure the temperature of both hot and cold liquids and see at which temperatures the propeller will start and then stop spinning . It may take a few minutes so record the time as well.

    Where can i buy teg in Delhi?

    U can buy it from ebay.....

    Can we use the TEG for charging a phone by using the heat produced by the phone itself?

    The three-dimensional photovoltaic system is already on sale, is up to 20 times more efficient than a conventional solar panel. A major revolution in the production of solar energy, especially for those who have little space available.

    The first manufacturer to sell this system is called Sun-Säule.

    Not with a phone...There needs to be sufficient temperature differential between the hot and cold sides. Phone wouldn't get that hot (at least you would hope not) and what would you use for the cold side?

    Hi, cool project.

    Does it matter which side of the Thermoelectric Generator faces the hot side?

    Also, did you measure how much electricity was generated?

    I fancy trying this out for myself!

    Cheers

    I did some research into peltier modules during my senior research last year. It does seem matter which side of the Thermoelectric Generator (TEG) faces hot/cold. The TEG has a hot side and a cold side. the easiest way to find it when the TEG module is unlabeled is to hook a battery up and feel which side gets warm, then take a sharpy and mark the sides when you test them, otherwise you will forget as soon as you set the module down. However: CAUTION! DO NOT run a peltier module without a heatsink on the hot side.
    Also, you will find if you search them out, that there is a difference between a peltier cooling/heating module (kinda cheap) and a Thermoelectric Generator (quite expensive). In my research I didn't determine what the performance difference was between the two types. also my research ended up changing to solar PV encapsulation, so I stopped fiddling with TEGs.


    To ScienceKitStore, I enjoyed the instructable! I think TEG has a huge future in energy production, so I get excited to see people work with them.

    Thank you for your input, your information was accurate and useful. I agree that TEG and TEC(oolers) have a bright future.
