In the future, if humans want to conduct "interstellar migration", Mars, which is the most earth-like in the solar system, will become the first choice.
According to foreign media reports, recently, the Yang Peidong Laboratory of the University of California, Berkeley, launched the "Artificial Photosynthesis System Version 2.0", which is better than the first-generation system developed in 2015.
We all know that it is unrealistic to rely on rockets to transport all kinds of materials needed for human life, such as oxygen and fuel to food and medicine. According to Professor Yang Peidong's plan, the "Mars Immigration Plan" may be realized as soon as possible.
It is understood that from 2010 to the present, researchers in Yang Peidong's laboratory have been studying an artificial photosynthesis "circulatory system" that combines microorganisms with non-biological materials. The system converts carbon dioxide and water into the basic components of organic molecules by absorbing solar energy.
Yang Peidong said: "The silicon nanowires in this system are essentially similar to antennas. They capture solar photons like solar panels. These silicon nanowires then generate electrons and provide them to the attached microorganisms. Finally, the microorganisms absorb carbon dioxide Perform a chemical reaction and produce acetate. "
It is reported that while the system produces acetate, it also produces oxygen.
Yang Peidong added: "96% of the Martian atmosphere is carbon dioxide. Our system absorbs solar energy through silicon semiconductor nanowires and passes them to the microbes on the nanowires to carry out chemical reactions."
In addition, due to the natural advantages of biological systems that are "self-replicating", people will not have to rely on rockets to launch more things when they are engaged in space missions.
Like general Automatic Sliding Door operators, Ningbo GDoor Automatic Curved Sliding Door operators have supporting beams, running carriage sets, idle pulleys, back up battery, electronic mechanical locks, switches, etc.. The only difference is that automatic curved sliding door operators have curved supporting beams. And the interlock system for opening and closing achieves access control and energy saving. Interlock function upgrades the automatic curved sliding door into a security portal by a sophisticated coordination system of switches and sensors. And the double ID authentication and the video analysis system prevent forced accesses.
