Tsinghua University, China University of Pennsylvania and the latest research shows Acer Laptop Battery that bacteria can be dirty salt water into drinking water and electricity.
The study made clear the development of a microbial fuel cells a new direction. In the past, microbial fuel cells are often used to generate electricity or hydrogen or methane in the form of stored electricity.
According to the Discovery Channel reported that the University of Pennsylvania scientist Bruce Logan (Bruce Logan) said that the microbial fuel cell can be organic waste into energy source. Logan and other authors in the "Environmental Science and Technology" magazine (Environmental Science and Technology) published a related paper. Logan said: "In this latest discovery, Laptop Battery we believe that by changing the micro-power generation, we can deal with salt water for desalination."
The researchers first from ponds or other natural water samples collected. Millions of micro-organisms in the sample, some bacteria (scientists have yet to ascertain the type) will be automatically generated within their cells, electrons and protons, and they are transferred to in vitro. Other bacteria will absorb these electrons and protons, as the creation of hydrogen, methane and other chemicals such as energy material "fuel."
The researchers found that the use of two specially designed plastic film to take advantage of the energy generated by these organisms. This film can be produced by microorganisms isolated electron, ion, or gas, allowed to flow to the cathode or anode, respectively. Compaq Evo N115 battery Cathode, anode and membrane assembled in a small tissue box, as the same transparent plastic box. Between the film by adding a cup of pond water, bacteria start and, ultimately, can produce up to 90% purity of water.
The purity of water can be based on scientific or commercial needs to be adjusted, or even up to drinking water standards. Microbial fuel cell can be removed in the water most of the salt, because the process can reduce power consumption, it can also reduce the cost of water desalination.
The same is also studying the microbial fuel cells, Oregon State University, Liu (phonetic) said: "No matter how the treated water salinity,Compaq Evo N1000C battery which will be the first time the human microbial fuel cell used for desalination."
Liu said: "Using this method, basically do not need to input energy; if artificially added to the cells in the organic material they can even produce energy."
At present, both the dilute salt water to produce electricity or produce hydrogen, methane or other gases, microbial fuel cells are restricted to the laboratory. This situation will change next month, Logan and his colleagues at a winery near the installation of a large-scale microbial fuel cells, plans to produce wastewater into hydrogen.
Logan said: "At present this is only a demonstration project. But in the end wineries will be able to use the power Compaq Evo N1020V battery generated by microbial fuel cell-driven cars, forklifts and other vehicles."
