# Pyrolytic graphite temperature experiment

## Rational

It has been found in an

[experiment](https://www.nextbigfuture.com/2020/10/tiny-energy-harvested-from-brownian-motion-could-replace-low-power-batteries.html)

that graphene vibrates thus producing usable energy.

Pyrolytic graphite is composed of many layers of graphene, so it should be warmer than the

surrounding environment.

## Experiment Setup

The experiment consists of one [k type thermocouple](https://en.wikipedia.org/wiki/Thermocouple#Type_K) attached to

[pyrolytic graphite](https://en.wikipedia.org/wiki/Pyrolytic_carbon) in a thermally

insulating container. Another thermocouple is outside of the container. Both thermocouples are

attached to a thermometer.

## Experimental Results

The experiment measured the temperature difference between the two thermocouples averaged over a period

of about 80 minutes. On average the difference was found to be ~0.8F. The error in the measurement was

found to be less than 0.1F. The control experiment found the difference to be ~0.5F. This indicates that

the pyrolytic graphite is producing heat. The experiment was conducted at a room temperature of ~70F.

## Materials

* [pyrolytic graphite](https://unitednuclear.com/index.php?main_page=product_info&cPath=16_17_69&products_id=527)

* [meter](https://www.fluke.com/en-us/product/temperature-measurement/ir-thermometers/fluke-54-ii)

* [thermocouple](https://www.fluke.com/en-us/product/accessories/probes/fluke-80pk-1)

## Potential error

Pyrolytic graphite is conductive, so this could impact the thermocouple, but this would probably be noticable

in the meter readings.
