Porsche filled the fuel tank of its iconic 911 with a mixture of water and air, and the experiment succeeded.
The fuel was produced by a German company with funding from Porsche, It depends on extracting carbon from the air and hydrogen from the water to produce methane.
This achievement, if generalized, would mean coexistence with electric cars, near-zero exhaust, and even help improve the air condition.
