Toyota says exhaust water from Mirai FCV is safer than milk, but don’t drink it!

Exhaust water from the new Toyota Mirai hydrogen fuel cell car is safer than milk, so says the Japanese carmaker. Unlike other vehicles that emit harmful carbon dioxide, the Mirai only emits heat and water as byproducts. Seiji Mizuno, who is in charge of designing the car's fuel stack power generator, disclosed that they tested the health impact of drinking the exhaust water in a special lab.

The result? He said that compared to drinking milk, the exhaust water from the Mirai contains much fewer organic impurities.

Despite the results, Toyota still doesn't recommend drinking the exhaust water since it is created by sucking in oxygen from the surrounding air and bonding it to hydrogen from the fuel tank.

Mizuno that depending on where the Mirai is being driven, some locations in the world might have certain issues -- like organisms like E. coli – that could be hazardous to one’s health.

"You never know what the quality of the air intake is," Mizuno said. Likewise, the chemical process happening inside fuel stack power generator does not include sterilization or distillation. The exhaust water is also slightly acidic, but is less acidic than acid rain and beer.
