Moon bases could be built using astronaut urine
- Kaibeezy 7y agoTransporting materials to the moon is expensive ... This is why so many things designed from space travel are lightweight. Whaaaat?!
- Zenst 7y agoCost to get things into orbit is expensive - I don't have the numbers but the amount of extra fuel for every pound is, though roughly 90% of the weight of any launch vehicle is fuel. So if you can have something lighter do the same job, then costs etc really start to factor in hard.
- Zenst 7y agoCertainly a headline I'd never of predicted seeing in my lifetime. However, currently they recycle urine into water. So whilst this may work, you would be needing more water to produce more urine. What I've always wondered is, old satellites, they often get put into an abandoned outer orbit, why not crash them onto the moon for later use/recycling. Though equally mindful that some have unfriendly power generating inside, so that may preclude such avenues.
- gshdg 7y agoThe article seems to suggest that they’re using the components of urine that are left over once you evaporate most of the water for recycling.
- Zenst 7y agoMaybe, though i'm not so sure and not best article explaining it at all. I'm not aware of any concrete that doesn't need some liquid to bind via chemical reaction, so again - confusion rains.
