The people who claim that finally they were able to develop a car that can be run by water should be given the benefit of the doubt. Why is this necessary? Because this assumption doesn’t even have a concrete premise that you can run your car on water. Though this claim seems to have plausible hypotheses, don’t be deceived immediately because in practice, water alone cannot run any vehicle. On the other hand, let’s try to defend their claim for the meantime, probably when developers of this idea said that they can run car on water, they will use water to integrate in other fuel system to produce two power systems, which justifies the idea of hybrid cars. However, if this is not the case maybe the idea run your car on water is actually the HHO gas developed by Denny Klein which totally in some time leave people hanging, whether it is real or just a complete product of deception.
