Kolónia ma Marse bude postavená potom a krvou

<B>Preprava stavebného materiálu na Mars by bola extrémne drahá. "Marťanský betón" na stavbu kolónie by ale mohol byť vyrobený z miestneho prachu zmiešaného s krvou, močom a potom.</B>

Postaviť kolóniu na Marse zo stavebných materiálov dovezených zo Zeme by bolo ekonomickou katastrofou. Len preprava jednej tehly zo Zeme na Mars by zrejme stála cca 1 mil. Eur. Vedci sa preto snažia nájsť spôsob, ako využiť lokálne zdroje.

Podľa najnovších zistení by bolo možné vytvoriť alternatívny betón zmiešaním prachu z Marsu s proteínom albumin, ktorý sa nachádza v krvnej plazme. Jeho pevnosť by sa dala ďalej zvýšíť pridaním močoviny, ktorú okrem moču obsahuje aj pot. Týmto spôsobom by mohol každý astronaut počas 2-ročnej misie vytvoriť odhadom asi 80 kg takéhoto špeciálneho betónu.

Mimochodem, to sis vzal článek v novinách a zkrátil ho na tři odstavce?

Áno, presne to som urobil :) Okrem toho som ale tiež overil v pôvodnom článku (https://www.sciencedirect.com/science/article/pii/S2590006421000442), že novinári napísali naozaj to, čo sa v ňom píše (stáva sa, že novinový článok úplne nezodpovedá tomu, čo sa píše v origináli). Každopádne sľubujem že sa polepším a minimálne budem z AJ prekladať články, ktoré v CZ/SK verzii neexistujú, aby to malo trochu vyššiu pridanú hodnotu. 😉

No keby to vyšlo na 50-litrový sud piva na jednu tehlu, asi by tam mohli radšej voziť tie tehly 😀

Na druhej strane, keby musel každý astronaut vypiť aspoň 5 pív denne, zrejme by našli dostatok dobrovoľníkov 😀
