"A battery that needs feeding instead of charging? This is exactly what researchers have achieved with their 3D-printed, biodegradable fungal battery. The living battery could supply power to sensors for agriculture or research in remote regions. Once the work is done, it digests itself from the inside."

I was just going to say, machines powered by consumption of organic materials is exactly how the Faro Plague began in Horizon: Zero Dawn.
