Run car on water ???

[jpskiller]

not sure is this has been discussed before but i've noticed alot of people are now building these kits and converting there cars to either run fully on water or just partial to help with MPG, but are mostly in the states or china

http://runcaronwater.weebly.com/

there lots of examples on youtube of people using these.

has anyone tried this yet, or are the laws preventing us doing it over here in UK..

if it can be done what would the side effects be, ie emissions etc..

It's such utter horlicks it's not worth discussing I'm afraid.

Why, there are people out there doing it and it works so why is it *ollocks

You have to be a little sceptical of anything which claims to be 'easily assembled from items available at your local hardware store'

(are there any hardware stores left in the UK?)

Maybe you should give it a go and report back

OK but what about the theory behind this??? might not be that simple to build but who knows....http://uk.youtube.com/watch?v=ziTh2kq6CVw

I bet the oil companies are really worried about this, you only have to spend $40 on a book to teach you how to do it.
I wonder if the book burns too

If you find away of running my car on water I'm all ears...

And your a billionaire

Have to say the old saying if it looks to good to be true is probably is....

These theories, I'm sorry to say, break the laws of physics where they claim "free" energy .

It's of course possible to generate energy out of hydrogen, either by direct combustion or through a fuel cell.

However, generating the hydrogen by splitting water molecules requires energy itself.

The energy you can generate out of the hydrogen you have extracted from the water is less than the energy it will take you to split the water molecules in the first place.

So, these systems end up being net energy consumers rather than producers and that energy differential has to come from somewhere, i.e. the conventional engine, an external power supply, etc.

Hydrogen cars might or might not be part of the future (although the practicalities of hydrogen fuelled cars on a mass use scale seem to make that not a likely outcome), but they are no perpetuum mobile I'm afraid.

Running on water
snake oil anyone?

Cheers, a friend at work is thinking of building on of these things, so I just wanted to check it (not being scientifically minded) I had no idea, only problem is he wont listen so I will wait and see what he comes up with.

As a project I see nothing wrong with it; he will probably learn a lot from it.

Ultimately if it means he has to charge his car battery every night (which costs pennies) and he gets a 5% improvement in mpg (which is a saving of about £3.50 per tank) then he might break even on the project. If he gets better results then he's onto a winner.

Scientifically it makes no sense but science rarely takes an interest in the price of things. This is not efficient by any stretch (as it uses more energy than it produces) but if the relative costs of the energies in use are quite different then the financial efficiency might make it viable.

This crap has been flying about for a long time I wonder why it is still doing the circuit if it is a load of b------s.

What is trading standards all about

There is this slightly more sophisticated approach from Genepax in Japan http://uk.reuters.com/news/video?videoId=84561

It sounds quite good until you read the line "The car has an energy generator that extracts hydrogen from water that is poured into the car's tank." they fail to mention this energy generator probably uses chemical stored energy in the form of metal hydrides to release the hydrogen used in the cars fuel cell. http://en.wikipedia.org/wiki/Water-fuelled_car
It would appear the laws of thermodynamics are still safe for the moment then.

yes you can run a car on water but not for long if u were doing drag racing or some thing for quick burst it would work. i have seen this only once on a 1/4 mile run. not on an everyday running car. there is also a video of the car on you tube if you type in water powerd cars should help ur question!

 

[wrblue]

ok you have been on you tube sorry my mistake not reading the whole post!!!!!

Seem to remember wartime aircraft piston engines having a water injection system to give a temporary power boost. That works but if it was practical for everyday car engines some car manufacturer would do it. Probably muck up the catalyst?

Car manufacturers already do it on ultra-high performance cars with big turbos and intercoolers but the water plays no direct part in the combustion process. The water is sprayed over the radiators and intercoolers to reduce the air temperature and therefore increase density allowing for a bigger explosion and more power. You can get aftermarket kits for this too - this is proven technology .

Early motor vehicles did run on water, it just needed heating to boiling point.

so one need to have a kettle handy then

Water injection (directly into the mixture) is also used in cars - Saab 99 in production and lots of aftermarkets kits for turbo's before intercoolers become more popular. I remember a CCC Turbo kit test circa 1984 where one of the kits had water injection.

As with an intercooler it's primary purpose is to cool the inlet charge and so make it more dense, also it does lengthen the burn time so reduce pinking.
