Power from biological sources
An interesting article on the subject, published on 19 May in a local English daily, deals with the possibilities of cellular biological 'germs' interacting with light and water to produce electricity. It is indeed a revelation to me! My idea is limited to the production of methane gas from solid animal and human waste only. This is a totally different concept. In our interest BCSIR laboratories should study this matter and try it out experimentally to develop a working pilot plant. It will be the salvation of Bangladesh, and no less!
However, as I am ignorant on the subject; I could not understand the writer's statement, which I quote: "Algae and Cyanobacteria have hydrogeneses that use sunlight to split water and generate hydrogen without releasing any CO2" This release of CO2,however confuses me, as water splits up into hydrogen and oxygen by electrolysis. If hydrogen is used, then the oxygen is released. Where does the CO2 come from? Is this a misprint; or is there some organic reactions beyond my knowledge limited mostly to inorganic chemistry.
I shall be grateful for a clarification on this CO2 release from the writer of the article or anyone else who has the knowledge about the subject! I believe a commercial solution about the Algae culture and the set up needed to harness the hydrogen gas, even if it has traces of CO2, will be an excellent source for electricity in Bangladesh since our geological resources are small and finite.
