Toyota: Don't Drink The (Mirai's) Water

Want to literally taste the future? Toyota would like for you to reconsider that notion.

Automotive News reports the 2016 Toyota Mirai’s exhaust — consisting of water vapor and heat — may have “much fewer organic impurities” than milk, per the FCV’s fuel stack power generator designer, Seiji Mizuno, but what impurities the byproduct does have depend on what passed through the stack in the first place:

Depending on the place you are driving, some parts of the world might have certain issues, such as organisms like E. coli, which could be hazardous to your health. You never know what the quality of the air intake is.

That said, if you are interested/desperate enough to wonder if the Mirai produces Evian, you’ll be happy to know that the water is said to be “slightly acidic,” with a pH of 5 to 6, just below the levels found in acid rain and beer.

    "...with a pH of 5 to 6..." Kinda like Kool Aid; The "Hydrogen is our future" stuff.

    If Bear Grylls were in a pinch, he would drink it.

    Does anyone know of any decent research about what the possible effects (environmental or otherwise) of all the water vapor emissions resulting from a large-scale switch to hydrogen fuel cells would be? Would we see an increase in the amount of precipitation in certain areas? Would we see the Earth cool due to increased cloud cover? Would we see constantly damp roads and run-off of more acidic water into the water table, lakes, streams, and rivers? Would nothing happen? I've done some (admittedly rather desultory) searches for such research and come up empty handed.

      @srogers The water vapor has no effect. But with widespread adoption of FCVs, it's possible that the hydrogen that inevitably leaks out into the atmosphere could damage the ozone layer.

    Hmm just had an idea for an accessory for fuel cell vehicles that uses the exhaust heat and water to brew up a nice fresh cup of coffee or tea ready by the time you reach your destination...
