"The limiting factor in urine distillation is actually the high level of calcium

    ways to compound one another."

With humanity's future probably (?) driving more of us to leave the planet, I'm glad these things are being studied. Where there's a will, there's a way.

> On the Mir space station, this used to happen organically. Collecting water was a grubby job that involved chasing beach-ball sized spheres of condensate around the colder parts of the spacecraft with trash bags before they could climb into the walls and cause mayhem. Crew members spent three to four hours a day on this dirty and difficult task.

That sounds, frankly, horrible.

It made me think that the average space module probably smells like moist, reheated ass, too.

It's a cliche that space exploration creates discoveries that improve life back here on Earth. In the topics discussed in this essay, water reclamation and waste recycling especially, the future solutions developed I think will lead to improvements for terrestrial living.
