12 10 12 Mud Current POTD

Jordan Antetomaso, a Penn State sophomore majoring in biochemisty, examined the glow of an LED light from a microbial fuel cell filled with mud that he constructed in his microbiology 202 class. Students built experimental fuel cells with the goal of harnessing enough energy from random mud samples to light a small LED. The current is being generated by bacteria from the soil sample. Research at Penn State is attempting to harness more and more energy from the bacteria found in soil.
