To develop a mud battery that produces the highest voltage.
“Generate Electricity from Bacteria in Mud” – Make magazine has another design for a mud battery that utilizes 2 containers and a salt bridge (which differs from the MudWatt, which uses 1 container)
A handout that features yet another design for a mud battery that also utilizes 2 containers.
“MudWatt Assembly Tutorial” – this video shows how the MudWatt kit is assembled. Even though you are not allowed to use the MudWatt in this lab, it is useful to see the basic set up of a mud battery.
“MudWatt Microbial Fuel Cell - How It Works” – this video also shows the individual parts of the MudWatt and how they work to produce a voltage.
