Are there any cars out in the market that are fueled by water?

Question

ok so 4 yrs ago when i was in 7th grade, someguy that i think it was a scientist, went to our class and then he took us outside where there was this car that ran on water. the car was in experimental phase still, so i was wondering if they are available on the market.

Answer 1

Not in mass production. I'm sure you could buy a conversion kit but that will be expensive.  

Answer 2

No there are none that are readily available for purchase. Its amazing in this day and age, NO ONE can develop anything compareable, strong efficient or reliable as an internal combustion engine. Or maybe in this day and age masters and phd's mean nothing except you wasted alot of money in school(people were smarter way back when)

Answer 3

These are scams.

As the saying goes - If it sounds too good to be true, it usually is.

Every time the price of gas spikes, you see more and more of these devices advertised.

There were lots of them in the middle 70s during the oil embargo and gas prices spiked.  They didn't work then, they don't work now.

The current batch of devices claim to work by using electrolysis to separate hydrogen gas from water then feed it into your intake manifold.  The rip-off is that an automotive electrical system does not produce enough electricity for the system to manufacture enough hydrogen to make any difference.

An automotive electrical system would need to produce about 500 amps of electricity to make enough hydrogen to make any significant gains. Most automotive alternators produce about 100 amps, give or tale a little.  How does that 30 amp wire going to the little box carry 500 amps of power? Where does the required 500 amps of electricity come from? How does your 100 amp alternator supply 500 amps of power to the device and still have enough power to run the electrical system in your car?

Stop and think about it.  If there were a device that really worked, the automobile manufacturers would be all over it.  If General Motors, for example, could put a device in their vehicles that would give them a fuel efficiency advantage over their competition, they would buy up the patents and have them in every vehicle they make.

They would not be sold on some obscure website by some person selling them out of their garage.

Answer 4

There are some that run on hydrogen, but anyone who invented one that ran on water would probably just disappear one day.

He or she would find themselves in the sub-basement of some oil company building.

Answer 5

I think a few car manufacturers are trying to come up with a hydrogen vehicle that can be put on the marketplace.

I am sure that BMW is not the only one coming up with this, but we will have to wait and see if it actually catches on because of the lack of hydrogen refueling places.
