Could it be possible to invent a car that runs on water?

Question

Like that of Stanley Meyers had been working on before he died/murdered?

Answer 1

just water no.

mainly water maybe.

Answer 2

I saw one on tv amazing car.. i believe General Motors or some similar co. bought all the rights and buried it..

Answer 3

well the first train ran on steam ,,,why not,,

Answer 4

I believe they have already invented cars which run on hydrogen, not sure about pure water though.

Answer 5

Water alone, and non-nuclear ... NO.

Water is an oxide. There's no chemical energy

available.

You might 'burn' water in fluorine gas, but the exhaust

would be corrosive and highly toxic.

(You wouldn't want to be around, and it costs

energy toget the fluorine.)

There were cars that ran on acetylene gas, produced

by the reaction of water with calcium carbide.

(But it costs energy to make the carbide.)

You can get hydrogen from water by reducing it with

a light metal or by electrolysis, but the metals and/or

the electricity cost more energy than you get back.

Water injection can, if done properly, improve the

efficiency of an internal combustion engine, but

the energy doesn't come from the water itself.

If we ever figure out a small enough fusion reactor,

there's a possibility, but don't hold your breath

waiting for that.

In the matter of energy, "There ain't no free lunch."

Answer 6

not really... water can be used to generate energy but only in large quantites, (research hydroelectric dams)

Answer 7

idk it's probably possible. But there has to be better ways than petroleum!!

Answer 8

Only on steam!!

Answer 9

Theoretically, a large electical source could electrolyse the water to release oxygen and hydrogen.

The hydrogen can be used as a power-source for cars by burning it.

You wouldn't electrolyse the water IN the car, though - you'd be better off just using the electrical source to power the car directly. But performing electrolysis in this way in large stations, and then using hydrogen as a fuel for cars is one theoretical alternative to gasoline.

Answer 10

I doubt, there needs to be something that you can turn the water into that has less energy.

For example hydrogen and oxygen have a lot of energy, then they form water they have less energy overall, because energy is released. Basically you can't make energy out of nothing this would be perpetual motion which is impossible.

But if there were such an invention the oil and automotive companies wouldn't allow it

Answer 11

i don't doubt that such a car has been tried already, but of course, we don't have an unlimited supply of water, and pretty soon we're going to be paying $4.50 for water too.

Answer 12

not really....unless the car runs on some other form thats not combustion its not possible with the technology we have right now. its because water has ph of 7, or in other word its neutral. so its not reactive,flammable,or anything. so  as of right now,no.

Answer 13

Supposedly, it already exists.  However, I have my doubts....

Here's the 'rub':  The websites all claim the same basic chemistry for these engines.  The car uses electrolysis (which is running an electrical current through water to seperate it into oxygen and hydrogen).  O.K., fine.  I did that in eigth grade science class.

Then, the car engine burns the hydrogen and the oxygen to create energy....

However, when you burn hydrogen, you must mix it with oxygen...and... you get...WATER!  So...where is the energy coming from?  If you start with water and you end with water...then you have used up a bunch of energy to get the same product....it just doesn't make sense....the laws of physics state that energy can't be created out of nothing...and if the end product is the exact same as the beginning product, you haven't created any energy.  In fact, you've USED energy, in order for the electrolysis to split the water apart.

So...until I see some proof, I'll withold my judgement.

Answer 14

I'd thank you times a million if you did that! :D

Gas is sooo expensive these days. DX

Answer 15

of course , it is possible.

only you have to floaters in place of wheels

Answer 16

To start off with, whats the point? Alot of places are in drought, were running out of fresh water..........It would be more usefull for a car to run on renewable energy.....and there are alot of those!

Secondly, i think there is a motorbike which runs on water (or does it emit water) I FORGET, but anyways....

Answer 17

The short answer is no.

There are websites (some listed here) that claim you can use electrolysis to separate water (H2O) into H2 and O2, then burn that.  Yes, you CAN do that, but the very definition of 'burning' (combustion) is combining with oxygen.  So what you're doing is splitting H2O into H2 and O2, then recombining the H2 and O2 back into H2O!  You just got right back where you started, and that's why it doesn't work.

People HAVE actually built cars like this that run, BUT with a catch.  Either they are still mixing gas in with the water (thinking that they just need to 'get the bugs worked out' before they convert to pure water) or the energy is coming from the cars battery and when the battery runs dead the car is dead.

It's your entry level college chemistry, you can't get more energy out of a system than you put in.  It just won't work.  People who claim to have built it and made it work are people who don't understand their own creation.

Answer 18

Good question.Well I have some good news.The Japenese have already created a car that runs on H2O!Could this be the car to save us from these outrageous gas prices?I don't know.This could be the car.Apparently it runs on any type of water.Rain water,snow water,tap water,lake water...etc.Here's a  video to give you a glimpse of the new car.

Answer 19

Yes using water and electrical charge basically a hydrogen gas it can be seperated from the water at the place it needs to burn so there is no need to store hydrogen making it very much safer and yes cheap........... ask bush, blair brown why are they not investing in the technology as by now we should be using it loads, even welding of certain types can be achieved................... my neighbour has done all this type of thing, i though he was talking sh** but heay when you see it it is unbelievable............. check youtube too search bluebird hydrogen car and lisern to the distance the geeza got from i think 7oz of water and that was a mixed fuel but it still can be done with hydrogen alone!....................

Answer 20

yeah, i think they already have cars that run on water, i think i saw a commercial for it.

these cars release water vapor or steam (something like that, its water in some kind of state of matter) which is environmentally safe.

Answer 21

watch the whole clip, it will all become clear at about 35 seconds in

;)

Its a car....except....IT RUNS ON WATER MAN! ;)

Answer 22

No, all you have to do is separate the two hydrogen & the one oxygen parts that make H20, we all know that hydrogen is explosive, oxygen is too, they just need the right mix to release the required amount of energy to either power a form of internal combustion engine, which is not at all fuel  efficient, around 30% + or-10%, the rest wasted through friction & the rest, a huge amount in waste heat,so to continue with this flawed design would be wasteful.

someone already did go to the site below he found something for possibly curing cancer at the same time
