    The liquid, which the Palo Alto Fire Department has deemed to be a nonhazardous mixture of borax, lye (also called sodium hydroxide) and green dye, spilled out of the Tesla office at 1501 Page Mill Road onto Hanover Street.

      “Storage of sodium hydroxide requires a City permit, which Tesla had not obtained.”

      How is lye nonhazardous? Can’t it cause serious chemical burns? Maybe it’s just in low enough concentration that that’s not a concern.

        You don’t want concentrated lye, but diluted lye is safe enough to make soap. My question, and I’m not the only one asking in this thread, is- is a mixture of borax and lye a good coolant for a supercomputer?

        I guess you could argue that the green is so they would recognize a coolant leak…

          The lye concentration used to make soap is rather nasty if it gets on your skin and you don’t deal with it immediately. Source: I’ve made a lot of soap from scratch.

            Ah, that makes more sense then.

            But lye as well?

            Edit: never mind, that discussion says also lye.

              They use this mixture at my work as well. Flushing out large sub freezing cooling systems. We don’t dump it out on the street though.

                If it’s anything like the places I work, they specifically tell you to be very careful about what you wash away.
