BERLIN (AP) — The European Area Agency claimed Friday that human urine could one working day grow to be a handy ingredient in producing concrete to create on the moon.
The agency said researchers in a modern research it sponsored observed that urea, the major organic and natural compound in urine, would make the mixture for a “lunar concrete” more malleable just before it hardens into its strong remaining type.
It observed that utilizing only supplies out there on web site for a moon foundation or other building would cut down the need to start supplies from Earth.
The most important component in “lunar concrete” would be a powdery soil identified on the moon’s floor identified as lunar regolith. ESA explained urea, which can split hydrogen bonds and cut down the viscosity of fluid mixtures, would limit the quantity of h2o essential in the recipe.
“Thanks to long run lunar inhabitants, the 1.5 liters (3.2 pints) of liquid squander a individual generates every single day could develop into a promising by-item for space exploration,” it reported in a statement.
On Earth, urea is utilised as an industrial fertilizer and a raw material by chemical and professional medical corporations.
“The hope is that astronaut urine could be basically utilized as it is on a long term lunar base, with small changes to the water content material,” examine co-author Marlies Arnhof said in the ESA assertion. “This is extremely practical, and avoids the have to have to further complicate the refined h2o recycling systems in area.”
