MudWatt

Our MudWatt products are fun and educational science kits that use the natural micro-organisms found in soil to generate electricity. Microbiology, chemistry, and electrical engineering all in one versatile STEM-based kit!

Although we cannot see them with the naked eye, micro-organisms are all around us. One particular species of microbes possesses the unique ability to release electrons outside their bodies as part of their natural respiration. Each of our MudWatt kits utilizes this remarkable ability by providing mud-based microbes with two conductive graphite discs - the anode and cathode. The anode is placed within the mud where the electrogenic microbes can grow, and the cathode is placed on top, exposing it to oxygen in the air.
