Are there the incubator cultivate microorganisms that can be used to generate electricity

But these natural gifts of energy are accumulated over thousands of years of earth's crust, though they are plentiful, but they are limited. So people will eventually face an energy crisis. Of course, people can get energy from many sources. Solar energy, for example, is a huge energy source. In addition, like geothermal, hydraulic, nuclear fission can release a lot of heat energy. Experimental research shows that the use of incubator microorganism to generate electricity to show people the good prospects.
There are many types of batteries, and fuel cells are a rising star in this family. The general battery is made up of the positive, negative and electrolyte components, and the fuel cell is the same: let the fuel react at the end of the negative side and lose the electrons; Let the oxidant react at the positive end and get the electrons from the negative electrode through the wire. A bacterial incubator is the same as a normal battery, when a current passes through a wire. Fuel cells can be used as fuel for hydrogen, hydrazine, methanol, formaldehyde, methane, ethane, etc., for oxidizing oxygen, air, hydrogen peroxide and so on. Now we can take advantage of microbial life activities of the so-called "electrode active material" as the fuel cell, and then through the way similar to the fuel cell, converts chemical energy into electrical energy, become a microbial cell.
As the electrode active substance of microbial battery, it is mainly hydrogen, formic acid and ammonia. For example, it has been found quite a few bacteria can produce hydrogen, which belongs to can have more than 30 heterotrophic bacteria, and they can be fermented sugar, alcohol, organic acids and other organic compounds. Absorption of chemical energy to meet the needs of their life activities, at the same time, the other part of the energy released in the form of hydrogen. With this hydrogen fuel, you can make a hydrogen - oxygen - type microbial battery.
In a closed spaceship, what about the urine of the astronauts? NASA devised a clever solution: using microorganism bacillus to handle in the urine, and to produce ammonia, with ammonia electrode active material, get the batteries, such already dealt with urine, and got the power. Generally, in the space of space, each person produces 22 grams of urea a day, which can get 47 watts of electricity. In the same way, microbes can get nutrients and energy from waste water and produce the fuel they need. Although microbial batteries are still at the stage of experimental research, it heralds a future that will provide more energy for humans.
