Electricity from sewage
ASHRAF Ahmed, a former teacher of Dhaka University now involved in biotechnology research in the United States, has published an important and exiting article on a new application of sewage, published in the pages of a local English-language daily on August 20. It opens up an unexplored area of microbiology, which we normally associate with bacteria and germs. He called the new area of technology as ‘electro-microbiology’ and has established the possibility of generating electricity from micro-organisms, interacting with sewage resulting in production of electricity.
Based on this fundamental research, there is every possibility to have microbial fuel cells, instead of generating foul smelling gases and sludge, disposal of which is a big problem involving costs. One can say that he is on to finding out a new way to convert waste to wealth.
Not being familiar with microbiology, I could not clearly comprehend the formation of conducting wires by microbiological action that enables electrons to move between high and low potential cells. It seems that this idea can result in having a fuel pack, similar to the common storage battery that we use in automobiles.
I am sure that scientists concerned at the Bangladesh Council of Scientific and Industrial Research will or have already gone through more details about this new concept of generating electrical power with no need for conventional fossil fuel, or the need for dangerous and highly radioactive nuclear fuel for atomic power generation.
I believe that, in our national interest, our authorities should support our scientists to be involved and keep abreast of the unique new source of pollution-free power generation possibilities. It is indeed an exciting and astonishing new scientific breakthrough.
