Many people in the past have claimed to run vehicles on water. But all of them have turned out to be frauds. It is very simple. If water could be used as a fuel, then it is the most abundant fuel on earth and there would have been no hassle in using other expensive fuels. Every student of basic sciences knows that water bonds do not have that much energy that could run an engine by mere splitting. It cannot be used as a fuel.
People will argue and as claimed by His Excellency Engineer Agha Waqar sb that water is first split into Hydrogen and Oxygen and then this mixture runs the car. For them, there is nothing wrong with this claim except that it is false. Hydrogen is also a very non-economic and inefficient fuel when used in cars. Much research is being carried out on Hydrogen to be used as fuel but the storage, economics and inefficiency are big problems.
