“Okay, technically I’m lying. The plants aren’t entirely water-neutral. They strip the hydrogen from some of it (releasing the oxygen) and use it to make the complex hydrocarbons that are the plant itself. But it’s a very small loss and I made like 600 liters of water from MDV fuel. I could take baths and still have plenty left over. NASA, however, is absolutely shitting itself. They see the water reclaimer as a critical survival element. There’s no backup, and they think I’ll die instantly without it. To them, equipment failure is terrifying. To me, it’s “Tuesday.”.”― Andy Weir, The Martian
