Agnirva Space Premier League - Expedition #32290: Powering the Future: Microbial Fuel Cells in Space

What if bacteria could generate electricity—especially in space? Microbial fuel cells (MFCs) are systems that use bacteria to convert organic matter into electricity. Valley Christian High School’s project investigated how these systems perform in microgravity aboard the ISS.

Their experiment examined if microgravity alters the electrochemical efficiency of MFCs. Since gravity affects fluid movement, the lack of convection and sedimentation in space could change how bacteria interact with electrodes and how nutrients circulate. Students monitored voltage outputs and compared results with Earth-based controls.

This research could support sustainable energy sources for long-duration space missions, where renewable, low-maintenance power is essential. Imagine astronauts powering tools or growing food using electricity from bacteria!
