Admittedly, we're still a long away from this even becoming a lab experiment given the complexity and scale that's involved. But technology like this could eventually be the power source necessary for small gadgets where self-sufficiency is important. The team discusses the idea of using the bacterial turbines for self-assembled devices that can't be tethered to traditional power sources. Although we'll probably have to have a serious discussion about the ethics of using living organisms, no matter how small, as a replacement for the battery. Especially since they won't be plugged into a VR simulation of the real world to keep them distracted.
