Bio-battery technology could open up a whole new field of science with exotic new applications. The study was partly funded by the Army Research Office Institute of Collaborative Biotechnologies, and the Army Research Office Institute of Soldier Nanotechnologies, which suggests that the Army has some interest in this type of research. One can only imagine the strange and/or nefarious possibilities of fusing batteries into living organisms. However, Belcher diffuses any excitement over possible cyborg applications.
