By providing an electrode for the micro-organisms to donate their electrons to, the electrons can be harvested as electricity.

For historical accuracy it must be mentioned that all early Telegraph Communications - like those used through-out the U. S. Civil War, and as the long-lines
communication that supplanted the "Pony Express " (Whose "Hey-day'' was less than two calendar years beginning to end !) was designed and used to generate
its energy from an earth based galvanic reaction between the Cathode / Anode plates buried in the ground.

Some unscrupulous person, on the other hand, may try to sell this design to someone with the advertisement that it IS creating power from the plants, IMPLYING that the anode and cathode won't quickly corrode away.
