u can make ur own generator and use it in certain emergency conditions

lets have a look in how to build a Thermoelectric generator..

Step 1: Step 01

we need

1. Peltier plates 12v

2. some metal case and stand

3. boost circuit made or bought as module some screws

4. some strong adhesive

5.voltage regulator

6. adhesive

Step 2: Step 02

fix the metal case onto the stand where the holes are provided and make it fixed

place the peltier plates in and take out the wires through the holes provided to make the plates to get stabilized in the case

find some heat insulating small tubes to prevent the contact of wires along the case.

place the Peltier plates and then place the metal plates onto the plates and make it to be stabilised for some time and then ............

place some adhesive in its sides to prevent the flow of or leakage of cold water going to be poured in.

place the candle and the boost circuit in their respective positions as shown in the figure.

if un able to get a module make one using the components necessary and make a boost module on the bread board.

important notes

1. make the cold water enough chilled to make the heat produced by the candle to get heated.

2.if u make a boost module u must provide separate input voltage for the boost module.

3.use a voltage regulator for better safety.
