Water powered engine is still a mysterious term for the people. They have a vague idea of it to be a car engine with regular water flowing through its pipes and tubes. They don't recognize that the water-powered engine is actually a hydrogen engine. Water-powered engine uses water for the sole purpose of getting hydrogen gas. The hydrogen gas once generated is then combusted. The car is powered by the use of hydrogen gas.

Many technicians have worked on the making water-powered engine following the laws of thermodynamics. Many of them have even claimed to invent the water-powered engine. But all the claims of the invention of the water-powered engine have been declared as fraudulent. Various swindlers have attempted to make a lot of money from the pocket of innocent investors by selling them fake kits. The debate surrounding the hydrogen engine (or the water powered engine) is still raging. Passionate people stand on both sides of the fence regarding the issue.

Some people are against the making of hydrogen car or the water-powered engine as they are afraid of the possibility of an explosion. Hydrogen and gasoline are both extremely explosive and inflammable gases. The memory of the Hindenburg explosion during World War Two is still fresh enough to make people tremble and it is this memory that creates the most disagreement against the initiation of the water-powered engine.

The people are also doubtful about the storing of hydrogen, as it is a huge problem. The hydrogen has to be tightly compressed, so as to store enough to use on a drive. This isn't the right idea when the element is hydrogen. Of course there are also arguments for the water-powered engine. Proponents of these developments are quick to point out that gasoline is just as likely to explode as hydrogen is and a gasoline explosion is far more destructive than a hydrogen explosion. When a gasoline-powered car explodes the entire car will explode as a result of it. There is very less chances of passengers surviving in a gasoline explosion. Hydrogen, however, is a gas that floats to the top of the car, taking the explosion with it. This leaves the passengers safely underneath the danger.

The water-powered engine is also suitable for the environment. It will not cause any carbon emissions and will not be a drain on the earth's reserve of fossil fuels. Hydrogen will never be extinct because it can always be harvested from water.
