The next time you’re paddling down a somewhat polluted stream, you might notice a row-bot go by.
This tiny, bacteria-powered robot is more than worth its weight in waste reduction. As it skims the water’s slimy surface, hungry microbes within its mechanical “belly” are gobbling up garbage.
Garbage in, electricity out… After satisfying their yucky cravings, these tiny critters emit enough power to keep the row-bot moving along.
How this all works is that a “bacteria-filled fuel cell” within the row-bot receives protons and electrons from bacterial by-products. This, in turn, keeps the “electrical circuit in the cell flowing.” To keep the
row-bot on course, “the machine has four little stabilizers.”
