In fact, this solution is really straightforward, that is, self-produced and self-sold. It is to discharge these excrements from the human body, then realize waste utilization and turn them into food again, so that people can maintain their lives if they eat again. Having said that, many people may have a feeling of vomiting. I have to say, it really makes people feel that they can smell bad through the screen. Of course, we should also sigh that scientists have such a big brain hole that they can think of such a way.
It seems that in the future, these astronauts want to live in space, and they really want to start eating shit. But in fact, we live on the earth and recycle all kinds of materials. Although we don't directly eat or directly indicate the source of the food we eat, there are also some human excreta in crops. When the crops grow up, we eat them. Isn't this what we eat every day?
So there is actually a special circulation process, which doesn't mean that it can't be eaten without any treatment, so this team actually uses a special microorganism (Alpha capsulata), that is, people's feces interact with these microorganisms, so that they can change this excrement and make it into a delicious food, called yeast sauce, which can be eaten directly or indirectly with other foods.
Of course, this technology is not that simple. In fact, the chemical composition has changed, which means that these nutrients in the excrement have been extracted, and those harmful macromolecules can be directly separated and discarded. In addition, the nutritional components of these substances modified by microorganisms are not comprehensive, and they can be compensated by other means. In this way, it is no longer the original excrement after transformation, and it is similar to the food we usually eat. At least, the nutrients are sufficient. In this way, astronauts can eat delicious food in space, and now this special nutrient looks like vegetable paste. But I have to say that this picture is a bit discordant, which makes people feel a bit unimaginable. If this experiment really comes true, I wonder how many people will accept this food and how many people will actually eat it?
