Paper batteries and dirty water as a new source of energy

It is time for humanity to recognize that it is unprecedented dirtied the planet. And so, Willy-nilly, we have to develop a “microbial fuel cells”. Devices in which the result of the activity of bacteria is converted into electrical energy. And along the way, albeit narrowly, the purification of wastewater.

The Binghamton University studying the technology of freeze-drying the bacterial mass, to achieve the guaranteed recovery of microorganisms after starting the reverse process. This is to ensure that the fuel elements remained inactive, were not worn out in vain, and were activated only at the right time. And then we can bring the container with the dry “bacteria-electricians” anywhere, fill them with dirty water and get ready low-power energy generator.

The liquid should be dirty, but it is best to scoop straight from the bowl, before you press flush. Bacteria break down organic matter from the water to eat, and passing at the same oxidation processes affect the arrangement of electrons, thereby creating an electric current. In the experiment, scientists had increased in the few microwatt per square centimeter area of the battery, which is enough to make the led.

Storage of bacterial mass is used trap from cellulose, in simplified form, it looks like a rough sheet of paper that you want to soak in dirty water. Or to pee on him to put in a pool, leave it lying on the ground in the rain – from a practical point of view to apply such fuel cells is very simple. Yes, the efficiency is not great, but it’s an interesting way of extracting energy from “nothing”, moreover, straight from the dirt. Technology has great potential for use in areas of natural disasters.
