Bacilli Cell
Biologist predicts that the 21st century will be the times of bacilli power generating which benefit to mankind. As far as bacilli generation mentioned, it can be traced back to 1910, the British botanist utilize platinum as electrodes and put it into the coli-bacillus liquid that produce the first bacilli battery in the world successfully. In 1984, U.S. scientist work out a kind of bacilli cell used in spaceship, the active material of electrode is comes from pilot’ urine and live bacteria.
However, the discharge efficiency of bacilli battery cell is very low at that time. By the end of 80’s of 20th century, bacilli power generation has important breakthrough, the British chemist make bacilli to decompose molecule in the cell pile, release electron to do movement to anode so that generate power. Their measure is to add some aroma compound, such as dyes into sugar liquid as diluents to improve the electronic transmission ability of biological system. During bacilli power generation period, the battery need to be inflated continuously to churn up the mixture of bacilli liquid and oxidation substance. It has been calculated that utilize such bacilli cell can get 1352930 Coulomb energy per 100g sugar, the efficiency up to 40%, the efficiency is outclass the current cell we use, it also has 10% potential waiting to be dredge up. You can get 2A current as long as you add sugar to the cell continuously, and it can last for several months. Now sony (VGP-BPS8) is research the apply of Bacilli Cell.
Making use of the principle of bacilli power generating can build up bacilli power station. A 10 meter cube container to full of germ-culture liquid can establish a 1000 kw bacterial power station, The consumption of sugar is 200kg per hour, the cost of power generating is higher some, but this is a kind of green power generation station which won’t pollute environment, much more, after technology developed, the sugar liquid can be replaced by sawdust, straw, fallen leaves and other waste organism. Hence, bacilli power generating has a very attractive prospect.
At present, every developed countries looks like the eight immortals crossing the sea, each demonstrating his skill: America schemed out a sort of comprehensive bacteria cell, the single-cell make use of the sunlight convert the dioxide and water to sugar, then let the bacilli utilize the sugar to make power; Japan put two kinds of bacilli into special syrup, let one bacilli devour sugar to generate acetate acid, then let the other bacilli convert these acids to hydrogen, the hydrogen enter into phosphoric acid cell to make power; United Kingdom think up a bacilli cell which take alcohol as cell fluid and dehydrogenase platinum as electrode. Now thye Bacilli Cell cant be used in laptop battery.
It was also surprised to realize bacterial also has a special power that it can catch solar energy and convert to electricity directly. Recently, the America scientist find a kind of halobacterium salinarium in Dead Sea and Great Salt Lake, they contain a purple element, when they receive around 10% sunlight they can convert it to chemical substances, and then generate electric charge. Scientists make use of them to create a small experimental solar energy bacteria cell, it is proved that the halobacterium bacterial can be used to generate electricity, the salt instead of sugar which lower the cost greatly as VGP-BPS8. This shows that allow the bacteria supply electricity to human beings is not a distant idea but the reality of the near future.
