Discover the POWER beneath your feet!
MudWatt engages kids in STEM in a whole new way, using the power of electricity-generating bacteria living in the soil beneath our feet!
How MudWatt Works
The MudWatt is a living fuel cell powered by the micro-organisms naturally living in the soil beneath your feet.
Although we cannot see them with the naked eye, with bodies one-tenth of the thickness of a human hair, microorganisms or “microbes” live throughout virtually all soil and sediment on the planet. Among these diverse communities of microbes are particular species with the unique ability to release electrons outside their own bodies during respiration.
Electron Flow Through the MudWatt
To understand how the MudWatt works, we need to follow the path of the electrons. Consider each step of the cycle below, using the diagram here as a reference:
1) While munching up the nutrients in the mud, microbes deposit electrons onto the anode.
2) These electrons travel through the wire to the Hacker Board, where they power the electronics.
3) The electrons then travel back down through the wire to the cathode.
4) The electrons interact with oxygen and protons to form water.
This sequence happens over and over again, trillions of times every second!
