Microbes are powerful in so many ways, including their ability to create power.
To help engage audiences in the applications of microbes that can create electricity I made a microbe powered tea light and microbe powered Jack-o-lantern.
Open Source Guides
I produced guides on how to create microbe-powered tea lights and how they can then be used to make microbe-powered tea light and jack-o-lanterns. Check out the guides on Medium or GitHub.
