Is it possible to convert heat to electricity using Peltier Module?

Click For Summary

Discussion Overview

The discussion revolves around the possibility of converting heat to electricity using a Peltier module, with a focus on practical applications and devices that achieve this conversion, such as thermopiles and thermoelectric generators.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant inquires about a chip that can absorb heat and convert it to electricity.
  • Another participant confirms that heat conversion is possible but notes that it is not very efficient, referencing automotive thermoelectric generators.
  • A third participant mentions the use of thermopiles in gas-powered appliances, explaining their function in generating a small amount of power to control gas valves.
  • A later reply seeks clarification on whether a Peltier module is suitable for absorbing waste heat from conductors.
  • Another participant suggests that the inquirer is actually looking for a thermopile, describing its structure and function as an array of thermocouples that generate electricity when heated.

Areas of Agreement / Disagreement

Participants present multiple viewpoints on the devices capable of converting heat to electricity, with some suggesting thermopiles as a more suitable option than Peltier modules. The discussion does not reach a consensus on the best approach or device.

Contextual Notes

Participants express uncertainty regarding the efficiency of heat conversion and the specific characteristics of the devices mentioned, such as voltage output from thermopiles.

I need to know because i need a chip that is a conductor and absorbs heat then converts it to electricity.

if you have a gas powered appliance in your home you have suh a device. it's the "thermopile" that is in the pilot lihjy flame. it makes a small amount of power to hold the gas valve open vial a small electromagnet, and if pilot light goes out the gas supply is shut off.

you can get one from a hardware store or a discarded water heater to tinker with.
i don't remember the voltage they make but i doubt it's more than two volts.
 
Thank you for the response!

I was looking for the chip that can absorb waste heat from any conductors then convert it to electricity... I'm not very sure if it's the peltier module.
 
Your looking for a thermopile.

A thermopile looks kind of like a peltier plate. It's composed of an array of thermocouples that output electricity when they are exposed to heat.
