fb86oonfws6k1xk large Lime Jello Fuel Cell

Makezine_COTM_Batteries-BadgeThis fun instructable by egbertfitzwilly shows how to make a microbial fuel cell out of jello, yeast, and carbon paper.

Here’s how it works, we’re going to mix a little Jello brand Instant Gelatin with some Fleischmann’s Active Yeast and a few drops of plant food. Once that solidifies we’re going to cut out some fun Jello squares (yes, they still jiggle) and, using the carbon paper as electrodes, we’re going to tap the energy produced by the yeast to create electricity.

This is an innovative form of the popular single cell microbial fuel cell or MFC. The gelatin serves a variety of useful purposes, including MFC container, fuel source and electrolyte. The yeast will feed primarily off of the sugar in the gelatin mix while the gelatin seals out ambient oxygen.
