17/09/2022 Second Workshop at Longdendale Environmental Centre as GUIDEline project with Glassball Studios: In this workshop, we continued to work on our boundary detectors; moss terrariums with carbon and aluminium layers which act as electrodes. In my test, I used moss growing on a carbon graphite felt layer (the anode), over a granular substrate of Zeolite (the electrolyte, but in the workshop, we used grit and mud collated from the boundary). The base of the jar is covered with aluminium foil (the cathode).  As the moss photosynthesises and microbes do their thing  - electrons are exchanged between the two electrodes generating electricity (more info on the science at end of this post). However, it is as yet unclear exactly how
