Helping Mars Migration Program: Second-generation artificial photosynthesis system turns carbon dioxide into treasure

In the future, humans will be the first choice to be the most Earth-like Mars in the solar system if they want to carry out “interstellar migration”. According tomedia reports, recently, the University of California, Berkeley’s Yang Peidong Laboratory launched the “artificial photosynthesis system version 2.0”, compared to the first generation of the system developed in 2015, “version 2.0” is even better.

We all know that it is not realistic to rely entirely on rockets to transport all the supplies needed for human life, such as oxygen, fuel to food and medicine. According to Professor Yang Peidong’s plan, the “Mars Migration Plan” could be realized as soon as possible.

It is understood that from 2010 to the present, Yang Peidong laboratory researchers have been working on a combination of microorganisms and non-biological materials artificial photosynthesis “circulatory system.” The system converts carbon dioxide and water into the basic components of organic molecules by absorbing solar energy.

“Silicon nanowires in the system are essentially antenna-like, capturing solar photons like solar panels, ” says Mr Yang. These silicon nanowires then produce electrons and supply them to attached microorganisms. Finally, microorganisms absorb carbon dioxide, react and produce acetate. “

It is reported that the system produces acetate, but also produces oxygen.

“Ninety-six percent of the Martian atmosphere is carbon dioxide, ” Yang added. Our system absorbs solar energy through silicon semiconductor nanowires and transmits them to microbes on the nanowires for chemical reactions. “

In addition, because of the natural advantages of the biological system itself, “self-replicating”, people will not have to rely on rockets to launch more when they are on space missions.
