According to the report of the British "Daily Mail" on November 27th, American researchers found through experiments that wastes such as excrement, discarded towels, food waste bags, etc. can be converted into rocket fuel, thereby reducing the amount of fuel carried when the rocket is lifted. Reduce the rocket load. Usually, the ashes produced by the astronaut are stored in the transport cabin. When returning to the earth, the transport cabin is separated from the main body and burned due to friction and overheating with the earth's atmosphere during its fall. However, if the astronauts live on the lunar surface for a long time, there will be more and more household garbage. It is not feasible to handle such rubbish through the transport cabin, and it is even less likely to throw the rubbish on the moon.
The researchers used the garbage samples provided by NASA as experimental materials and found that the daily domestic waste per person could produce 290 liters of methane. After removing the bacteria in the anaerobic tank, a mixture of methane and carbon dioxide can be obtained. The amount of methane accumulated over a long period of time is sufficient as a rocket’s return to Earth. In this way, when the rocket launches to the moon, it can reduce the amount of fuel carried, thus reducing the weight of the rocket.
Bacteria treated during anaerobic processes produce approximately 200 gallons of water (approximately 757 liters). After the water is ionized, it will get nitrogen and oxygen. Oxygen can be used as a backup oxygen for astronauts. After seemingly waste carbon dioxide and nitrogen have been treated, they can produce methane and water, which can circulate back and forth, and the available resources become more and more.
Researchers say that this method not only applies to space life, but also brings benefits to daily life. Methane produced from daily garbage can also be converted into fuel for heating, power generation and transportation.
