Brewery waste used for building homes on Mars
There is no doubt that a manned mission to Mars will take place sooner or later, and the first settlers will have to live somewhere. In this case, the material for the houses to be durable, inexpensive and withstand the harsh conditions of the red planet. And it so happened that the raw material for such material was found. Moreover, not in high-tech laboratories, and beer production plant.
According to the publication Nano Energy, a group of researchers from the University of Colorado led by Ivan Smalyuhom managed to develop a cheap airgel. Aerogels - a material with a rigid frame and a large (up to 90%) the number of cavities with bubbles of air or other gas. Because of this airgel is very light, its production takes a little raw, but because of the special structure of the frame rigidity is obtained sufficient to use Airgel as a building material. In addition, airgel has good insulating properties and is permeable to sunlight, but there is a drawback: the airgel mat due to chaotic internal structure. It is the last property and decided to change the team of scientists.
The basis of the framework of a new type of airgel is cellulose. It is very much in the waste brewing - wort, which is currently only utilized. Thus receive "cosmic building material" can be for mere pennies. Some plants will only be happy if they get rid of the huge amount of waste material. During the processing of the wort special kind of aerobic bacteria transforms it into nano cellulose filaments, resulting in a clear flexible film, wherein the heat resistance of such a material is so high that it can without problems be placed at some time in the fire. The authors believe that the new material can be used in space missions:
"Transparent, lightweight and durable heat insulator would help, for example, Martian colonists. You can "collect" the sunlight passing through the heat-insulating window and keep the heat indoors to avoid hypothermia and without spending resources on space heating on the Moon or Mars. "
In addition, the material can also be useful in the world for the manufacture of teplosohranyayuschih windows and even, according to the authors, clear winter clothing. The latter sounds very strange, but given the very extravagant tendencies of modern fashion, why not?
