Compost Energy: Microbial Fuel Cell and Effects of pH Alteration

The purpose of this experiment was to find out whether it was possible to convert food wastes into energy, and to determine the effect of changing the pH level of the fuel used for the device. The experiment was conducted by creating a sort of battery in which I used decomposing foods as the fuel. I recorded the energy produced every 12 hours and logged the rates at which the energy produced changed. At the end of my experiments, my idea proved to be successful, and energy was created. The food compost produced energy, and as I changed the acidity of the fuel further away from the prime pH level, the voltage went down significantly, indicating that the pH of the fuel affected the energy produced directly.

The measurements confirmed that my idea could be developed and expanded to a larger scale, in which I could create greater benefits for more people by creating a more inexpensive method of sustaining energy in homes, while reducing methane emissions released by food wastes and finding an alternative to fossil fuels as the main source of energy.

Some possible extensions to my project could be implementing it into institutions like schools, apartments, and houses.
