I have seen this announcement:

Bosch is a very serious company, so it may become real.

The government will figure out how to tax water used in engines.
Otherwise there will be a huge loss in tax revenue to the government:-)

Right now the gasoline tax in Europe is right around $5 a gallon.
Then there is the question of an increase in humidity with all that steam
coming out of  exhaust pipes  :-)

The water will have to be filtered as other wise it will leave deposits
in the engine and in the water tanks.  Filtered drinking water cost $1.28 a
gallon in the US grocery stores. About one dollar a gallon  cheaper than
gasoline in the US.

In California we have a water shortage so the price of food will go up
as the farmers use 80% of the total water supply :-)
