The latest entry is by designer Leonardo Manavella. The "Aqua H20" works both with human or animal urine. The liquid waste is handled via the Activated Carbon which removes both the color and the flavor.
No word on how this thing holds up against asparagus.
Once the urine is "cleansed" a container filled with fresh clean water is available for drinking.
The device is designed for drought-affected areas, or any sorta apocalyptic scenario starring Kevin Costner. But if it comes down to this or bottled water...then I am clearly fighting for the wrong team.
I'll just stick to writing my name in the snow.
