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.
Fuel Cell Vehicles (FCVs) are known for their high degree of energy efficiency. Aside from boasting ample driving ranges, FCVs have short refueling times. In addition, the only emission they make is water. With their great potential and environment-friendly nature, FCVs could be considered as the "ideal eco-car." Nevertheless, FCVs also require a special infrastructure: hydrogen stations, which are expected to be built starting 2015. By taking advantage of the expected sprout of hydrogen stations around the world, FCVs could lay claim to success in the future.
Toyota’s development works on FCVs have been ongoing for three decades, commencing development of Fuel Cell (FC) technology in 1992. The two core technologies inside FCVs – namely FC stack and the hydrogen tank – were results of independent development. Over time, they became the Japanese carmaker’s strong points. Now, after developing and fine-tuning the necessary technologies, the carmaker is introducing its first FCV to market -- the new Toyota Mirai – which is a Japanese term for "future."
The Japanese carmaker considers the new Mirai as a prime element of its dream to attain a sustainable mobility society. Toyota believes the new Mirai would allow people to move freely, comfortably and safely while still being friendly to the environment.
Concentrating on the next 100 years of automobiles, Toyota has indulged itself in developing a vehicle that could offer a new, distinct value. Toyota believes the new Mirai is as a pioneering vehicle that will play a role in establishing a Hydrogen Energy Society. Mirai doesn’t just offer its superior fuel cell technology and eco-friendly performance, it also delivers an enjoyable drive, a comfortable ride and a futuristic design distinguishing it as an FCV.
