Science Buddies: "Ask an Expert"

Hi, My daughter prepared 2 Microbial Fuel Cells one with salt added and the other one without it. After 9 days the voltage is still low 0.003 and 0.001. Can you please let us know what if this is something that is expected. She is using regular soil. We pick a soil we believe have high content of Ferric material (red soil) based on the documentation on the web site. Best regards Usiel

Hi Usiel - Because I am working with you and one of our staff outside of the forums on the questions you have, I am noting that here. Other Experts in the forums may also have feedback for you, too.
