Although it is a bit eschatological and disgusting, you have possibly ever wondered how difficult it must be to have to evacuate our waste in the international space station or in any other place where we are with gravity 0.

Aunque es un poco escatológico y asquerosete posiblemente alguna vez os habéis planteado cuan difícil ha de ser tener que evacuar nuestros residuos en la estación espacial internacional o en cualquier otro lugar en el que nos encontremos con gravedad 0.

Discarding the option of doing it upside down that I suppose would irritate the rest of the crew a bit, we only have the suction method that is actually the one used today in the international space station, with a specific container to treat the waste.

Descartando la opción de hacerlo boca abajo que supongo que irritaría un poco al resto de los tripulantes, solo nos queda el método de succión que es en realidad el que se usa hoy en día en la estación espacial internacional, con un contenedor específico para tratar los residuos.

Do not think that I spend the day thinking about this, it has come to my head when reading the news that I present today according to which my neighbors at the University of Alicante have developed a method to reuse the urine of astronauts properly treated.

No os vayáis a pensar que yo me paso el día cavilando marranadas, me ha venido a la cabeza al leer la noticia que hoy os presento según la cual mis vecinos de la Universidad de Alicante han desarrollado un método para reutilizar la orina de los astronautas debidamente tratada.

Two doctoral students from the University of Alicante have developed a system based on platinum nanocubes in a carbon matrix that are used as catalysts in an electrochemical device that will be tested in the space station.

Dos estudiantes de doctorado de la Universidad de Alicante han desarrollado un sistema a base de nanocubos de platino en una matriz de carbono que se utilizan como catalizadores en un dispositivo electroquímico que se probará en la estación espacial.

It seems that properly processed human urine can be transformed into ammonia and this ammonia treated electrochemically in this device by an oxidation process transforms the molecule into water and nitrogen from which energy is subsequently obtained.

Parece ser que la orina humana debidamente procesada se puede transformar en amoniaco y de este amoniaco tratado electroquímicamente en este dispositivo por un proceso de oxidación transforma la molécula en agua y nitrógeno del que posteriormente se obtiene la energía.

Water and energy will be very valuable things when human settlements begin to be built, for the moment on the Moon and Mars and in the future on other planets and for interplanetary space travel that has a very long duration.

Agua y energía serán cosas muy valiosas cuando se empiecen a construir asentamientos humanos, de momento en la Luna y Marte y en un futuro en otros astros y para los viajes espaciales interplanetarios que tienen una duración muy larga.

Go from here my humble tribute to these fellow citizens who give a bit of luster to this country, that really needs it.

Vaya desde aquí mi humilde homenaje a estos conciudadanos que dan un poco de lustre a este país, que buena falta le hace.

Si eso lo ponen a la venta me compro uno, para aprovechar al máximo el buen vino, que cuesta un riñón...

Pero lo convierte en agua, el que lo convertía en vino era otro. :-D

Entonces no interesa...

Hello @mauromar
I'll tell you that I never thought about what astronauts did before and how they did their basic physiological needs...
You have clarified a doubt for me.
A "bravo" for those Spanish creators, who have put their minds at the service of science.

Hello friend, a very interesting article, the truth I had never asked myself that question hehe, but honestly the smallest details can give us great solutions. I think it is a great project, everything that can be done for our planet seems excellent to me.

Thank you for your comment @franyeligonzalez.
