Unpleasantly steamy

The exhaust from Toyota’s new fuel-cell car, the Mirai, consists of water vapor and heat. I’m pretty sure nobody was thinking “Hey, water vapor! Let’s condense it and have a drink!” If anyone was, however, Toyota advises otherwise:

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.”

Then again, knowing Toyota’s tendency to keep beavering away at these things, I wouldn’t be too surprised to see a fuel-cell Sienna with an actual water fountain somewhere down the line — and customers griping about having to have the filter changed every 30,000 miles.
