America Engineers developed a new type of Battery by the seabed mud

U.S. scientists using submarine in the mud of organic debris, to design a new type of fuel cells. Prior to that, due to the high cost of replacement batteries, marine detectors are rarely placed in the remote area.
U.S. Naval Research Laboratory and Oregon State University scientists in the latest issue of “Nature Biotechnology” magazine reported that the diameter of 14 cm in two graphite disk electrode is installed, and drilled holes in the plate to increase the chemical reaction area. The researchers in which a small-buried in seabed sediments, and the other placed in water. Buried in the seabed of the disk gradually increase when the bacteria digest organic matter, the electronic concentration of the electrodes, and then electron transfer through the water and oxygen molecules to the surface of the electrode, the formation of current, the energy generated by a power of 0.02 mW, which is already enough to ocean-driven simple detector. Because the bacteria can continue to digest the organic material of biological debris from the sink to the seabed to be added, generating the raw materials do not have to worry about.
Earlier this year, there have been researchers found that the electrodes placed in laboratory tanks attached to some kind of bacteria after the passing of the current intensity between the electrodes can drive pocket calculator.
