According to Wai Cheng, a professor of mechanical engineering and director of the Sloan Automotive Lab where he does research on engine performance and emissions, combustion science, and energy conversion , breaking those bonds will always take more energy than you get back.
It would need equipment to split a water molecule apart and separate its oxygen and hydrogen. Then it would need to isolate each of them in separate tanks. Then you would need a combustion system that could mix and ignite them, or a fuel cell that could recombine them to make electricity.
The released energy could then drive a piston or run a motor and move the car. Without the right safety measures, a fender-bender could turn into an explosion worthy of an Avengers movie.

Hydrogen gas is used in these cars to add up more power.
The power adds up to the mileage of the vehicle and thus runs longer distance than the usual cars. Cars powered by water uses hydrogen to run.
The automotive industry is trying to build up water-powered cars. The method used in these cars is called electrolysis. Electrolysis will lead to the production of a gas called HHO.
This gas is also known as Brown gas. You can use only one quarter of water to run a car. This water will generate about gallons of gas. In the electrolysis process the power provider is none other than the car battery. Though it is still believed that the cars running on petrol are powerful yet, scientists are trying hard to utilize the energy from water to make these cars powerful. The advantages of using cars powered by water are many.
These cars run longer distance in less fuel thus are money savers. The engines of these cars are clean and more durable. These cars can be created by you in very less time.
The materials required to create this type of car are available in any hardware stores. Chemically, it's locked up in the atomic bonds between the hydrogen and oxygen atoms. When the hydrogen and oxygen combine, whether it's in a fuel cell, internal combustion engine running on hydrogen, or a jury-rigged pickup truck with an electrolysis cell in the bed, there's energy left over in the form of heat or electrons.
That's converted to mechanical energy by the pistons and crankshaft or electrical motors to move the vehicle. Problem: It takes exactly the same amount of energy to pry those hydrogen and oxygen atoms apart inside the electrolysis cell as you get back when they recombine inside the fuel cell.
The laws of thermodynamics haven't changed, in spite of any hype you read on some blog or news aggregator. Subtract the losses to heat in the engine and alternator and electrolysis cell, and you're losing energy, not gaining it--period. But enough about Genepax, which is sort of tangential to my main thesis here, and on to a more common topic in my mail que: HHO as a means of extending the fuel economy of conventional IC engines.
HHO enthusiasts--from hypermilers to Average Joes desperate to save at the pump--suggest that hydrogen changes the way gasoline burns in the combustion chamber, making it burn more efficiently or faster.
Okay, there have been a couple of engineering papers that suggest a trace of hydrogen can change the combustion characteristics of ultra-lean-burning stratified-charge engines. Properly managed H 2 enrichment seems to increase the burn rate of the hydrocarbons in the cylinder, extracting more energy. However, these studies only suggest increases in fuel economy by a few percentage points and don't apply unless the engine is running far too lean for decent emissions. That's a long way from the outrageous claims of as much as percent improvements in economy that I see on the Internet and in my mailbox.
The combustion chamber events are far different in the type of ultra-lean-burn engines where hydrogen enrichment has been seen to help. Ultra-lean means there's a lot of extra oxygen around for the hydrogen to have something to react with--far more than the very modest amount we're sucking in from the typical homebrew hydrogen generator made from a Mason jar.
