This instructable provides detailed directions for building your own microbial fuel cell using Jello, Saltwater and Septic Tank treatment. It's based on the information provided in Make a Microbial Fuel Cell (MFC) - Part 1 This is a true fuel cell in that both the anaerobic and electrolyte media are replaceable and the salt bridge may be serviced as needed. The fuel cell consumes organic material and produces electricity and methane ( or more properly biogas include CO2 and other gasses ). These are captured in a methane store for further processing....Okay, it's a balloon and I have no idea what you should do with the biogas except be careful and experiment with it.
We'll be using a traditional two cell design with a gelatin/salt bridge. I also intend to experiment with gelatinous nutrient medium in the anode chamber. The device has two relatively small chambers (approximately 100 mL). Now let's take a look at the materials we'll be using. A Tiny Toothpick Treehouse in a Bitty Broccoli Tree. Defusable Alarm Clock is Dy-No-Mite. LED Pong clock.
