Bioreactor for the production of oxygen and carbon raw materials on Mars (2 photos)

Recent events on Earth show that the idearesettlement to Mars is not without meaning and can become a vital event from narrowly focused scientific development capable of preserving civilization. However, the creation of settlements on the Red Planet requires a huge amount of oxygen, building materials, food and other necessary things, the transportation of which from the Earth, in the required volumes, is not possible with current technologies.

Scientists involved in the development of development projectsMars has already outlined the first steps to independently provide the colonialists of their settlements with all the necessary local materials. One of the most promising methods is to collect available on Mars in excess of carbon dioxide (95.32% of the atmosphere) with further generation of oxygen and organic substances from it.

Special experimental biologicalThe reactor was created by scientists from the University of California, Berkeley. The bioreactor is based on the natural process of plant photosynthesis, which allows the transformation of carbon dioxide into organic substances (sugars and carbohydrates) in sunlight.

A mixture is used in the design of the device.Sporomusa ovata bacteria and silicon nanowires, which are hundreds of times thinner than a human hair. Water is also added to the reactor, which will not be difficult to obtain on Martian glaciers. The efficiency of the reactor is comparable with the efficiency of the conversion of carbon dioxide into sugar using sunlight in sugarcane and amounts to 4-5%. At the same time, ordinary plants have an efficiency of photosynthesis during CO2 processing of only about 0.5%.

The chemical process in a bioreactor is associated withthe absorption of sunlight by nanowires, their generation of electric current with the transfer of electrons to bacteria. As a result, bacteria “absorbing” electrons turn two molecules of carbon dioxide and water into acetate and oxygen.
As a result, the colonists will receive much-neededto create an artificial atmosphere, oxygen, as well as acetate, on the basis of which any organic substances can be generated: fuel, plastic or medicine.
