Pak engineer makes car that runs on water

[Jango]

Where the heck did electromagnetism come into this thread????

The car can run on hydrogen combustion, water is electrolyzed, but energy is provided by a battery in the first place. So it is not perpetual motion and not feasible, in addition to not being possible.

That is what I am trying to find out....

Law of conservation of energy is at stake here. Now I believe world is going to end in 2012....

thermal energy can be directly converted to electrical energy ..some alloy material has the property to become magnetic when you heat it ..now place the material in a magnetic field and transfer heat to that material you gonna get electricity .. Burn hydrogen to get the heat ..now tell me where does your thermodynamics comes to the picture ?

Here thermodynamics comes into picture.

If people are still looking for a valid reason rather than blindly believing what is reported in the so called "NEWS channels", here are few facts.

Firstly, work is said to be done (in a friction-less perfect system) when there is a difference between positive difference between "Heat source" and "Heat Sink". Now electrolysis of water and combustion of H2 both produces 282.1 kJ* (286 kJ/mol: energy per mole of the combustible material ) and there is no diff between the source and the sink hence energy flow is IMPOSSIBLE . This was proven through Thermodynamics.
[Source: http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/electrol.html]

Secondly, now by physics, 1.5 liter = 1500 ml or 1500 gm of water. So, 1.5 liter = 83.33 mole of water (1 mole = 18gm of water). So its electrolysis should yield 83.33 mole of H2. And from above point the electrolysis of that much water should take 23,509.16 kJ or 6.53 kwatt-hours of energy. I am not sure that a humble car battery has that kind of power rating. Moreover the man himself says that the car has not be altered in any aspect so a high energy dense battery can be stricken from discussion.

Also that much amount of hydrogen would require 1868.972 L at STP and I donn think a car tyre can provide a oxygen-free environment to store that hydrogen (as shown in the video). Hydrogen is highly explosive at 4 - 74% concentration.

Plus I recall him saying he used distilled water. As far as I know pure water is not a good conductor of electricity, (and I can say that with complete confidence, as I have tried doing it at home 20yrs back. I had to add common salt) . Commercial electrolysis generally uses 25% potassium hydroxide. I did not investigate cathode material, but I know that it must be inert, e.g., platinum,but it is not require over an high-voltage. Another consideration is that one would probably need a fairly large surface area for the cathode in order to generate the hydrogen in a reasonable amount of time.

The reality is you gonna get energy when you split water in to hydrogen and oxygen ..and as all know hydrogen is a clean form of energy ..so theoritically speaking both are energy surplus equations and a lot of energy can be derived from water
our process of splitting water is not efficient ..there are efficient ways in nature for ex in photosynthesis the process of splitting water molecule gives energy .. So stating that car cannot be run through water because law of thermodynamics say so is absurd ..the thing is we yet not discovered efficient ways to split the water molecule

..there are efficient ways in nature for ex in photosynthesis the process of splitting water molecule gives energy ..

Now when you have audacity to drag biology into this, let me tell u one thing we are talking about molecular hydrogen which is used to produce energy on combustion (owing to high energy/weight value) not about ionic hydrogen which is used to make glucose in plants.

Also do not forget that Photosynthesis has an efficiency of 3–6% compared 50% and 70% for electrolysis.

In the off chance this is not a hoax, this is the claim:

Ahmad claims to be running his car successfully, using water as fuel for the last year. The water kit, is claimed to be simple and to have no complicated mechanism involved with it. It includes a "bubbler" that filters the water and then transforms it into hydrogen using an electrolysis process which is powered by batteries.

The generated fuel is then transmitted to the engine to run the vehicle. Ahmad requires that the car should use only distilled water, which is free of impurities. He claims that with only 1 liter of water, a light vehicle may run for 40 kilometers and motorbikes may run for more than 150 kilometers at speeds of up to 200 km/h. The water kit can easily be installed in automobiles especially in CNG vehicles. It is claimed that one may operate the engine by simply replacing the fuel pipes and that the water kit will cost only 40 to 50 thousand PKR (USD 500-600).[5] [3]

Perpetual motion is quite impossible.

The claim as I would explain by dumbing down (or smartening up, depends on your position on this matter) - Electrolysis process produces Hydrogen gas from the water fuel, Power to conduct electrolysis comes from a one time charged battery. Hydrogen is then used as fuel to burn to create kinetic energy for the car, the car moves and the dynamo recharges the battery.

Repeat.

My layman guess is, that if the power generating unit - the car engine (instead of something like a turbine engine), is not used and a much more efficient engine is used - still this can't produce perpetual motion. The losses of energy are too great. There is so much friction in the pistons alone, then there is the movement of the car, the tires grinding against the road, losses while breaking.

Unless the person is saying Hydrogen can burn to produce massive amounts of energy (far more than at least gasoline) - this just won't work. Literally chaar jamaatein pass banda keh sakta hai.

But yes ab shosha unfortunately chirrh chuka hai, toh baat ko anjaam tak jald hi lejana chahiye.

do you get energy by splitting water molecule ?
Answer is yes
do you get fuel from above process ?
Answer is again yes

theory is here ..now it is up to you to make this practical ..there is always a possibility of someone coming with a brilliant idea of splitting water molecule in a new way ..

How ? can you explain

Hydrogen is a clean fuel

Law of thermodynamics explains that perpetual motion machines are impossible.

Answer is yes

Ahem. . . . IMHO it requires energy to break the water molecule. That is, one NEEDS energy to break a water molecule.

Energy equivalent to bond energy of the molecule. Correct me if I am wrong.

Is that a rule ?
