Why can't they invent a car that runs off water, meaning the explosive power of hydrogen and oxygen?

Question

If you mix hydrogen gas and oxygen gas together without the heat, isn't it explosive? So if you had a car that could convert water back into these gases and then cause an explosion and channel the explosion into energy, why couldn't you use the energy to run the car?

Answer 1

yes you can. problem, you can't afford it ,i don't have the figures though you can probably find them on the internet.it will cost you more to produce the hydrogen than gasoline will cost you......tom

Answer 2

yes, but the problem is. Why?

Answer 3

Your assertion is false!

Answer 4

They already have. Stan Meyer who created the hho injector was poisoned by an exotic material that evaporated before his blood could be tested, so it looked like a blood vessel burst in his head (like Visine but works much faster). You can still find his patents on the canadian patent site, one of his best (and PROVEN) is the hho injector which uses the magic 21.4khz or above (depends on other factors also) oscillation to flash ionize h2o into hho atoms that are barely connected, so the hydrogen in it will give you as much or more power than gasoline, using only 9 amps or so total power for 8 injectors!!!  You can build other units like the hydrofueler which can cost up to $1000 to build, but hopefully soon people like myself will be mass producing these injectors.

This is ON DEMAND POWER FROM TAPWATER ONLY. It was proven and people are spending lots of time censoring the injector technology from youtube, google, yahoo. There is lots of hype about lame assist systems, and little about the good ones, I've found only 1 video of thousands of hho videos that show the Meyer hho injector working, but it works.

Answer 5

You're trying to break the conservation of energy law. The amount of energy gotten out of the combustion of hydrogen is exactly equal to the amount of energy required to turn water back into hydrogen and oxygen.

The net result: you get nowhere.

Answer 6

Look up fuel cell technology.  They are made now, though none are available commercially yet.  I hope to see it in the next 10 years.

I think you need to brush up on the technology, what you are describing is a perpetual motion machine.  Any combustion is going to loose energy to heat.  That being said hydrogen is the power of the future, but with current technology a fair amount of electricity in needed to produce hydrogen.

Answer 7

The 2nd law of thermodynamics-- you use more energy to extract the hydrogen than you get out of the hydrogen!  It's net NEGATIVE!

A fuel cell would work but they are very expensive-- Honda's new hydrogen car that they have begun leasing for $600 per month as a test cost ------------

$500,000  !!!!!  Honda says that in about 10 years they can get the cost down to ONLY $90,000 dollars  !!!!

Edit for BOB---  he has the correct answer--

Answer 8

The problem is that converting the water to hydrogen and oxygen takes energy, so you can't do it in a car.

What you can do is use a big nuclear power plant to change water into hydrogen and oxygen, send those things to a "gas station" designed to handle them, have a "fuel cell" in the car convert them to electricity, and run the car on that.  It's basically how they got electricity on the moon rockets.

People are working on doing all that to fight global warming, but it will take some time.

Answer 9

they did make a car run on water but they cant maintain it. But they are too busy with flying cars (which they are making lots of progress!)

Answer 10

You mean engine/motor that runs on water that you can put in a vehicle.

Water (H2O) can be truned into Hydrogen (H) and Oxygen (O) by applying heat pressure.  Hydrogen can be burned in an engine or used in a fuel cell to run a motor.  People can breath the Oxygen.

Answer 11

If U have a huge battery . The power needed to separate H2O into the gas requires about 300% more power than U can get from a generator run by just the motor.  So U might get it to appear that it works but the battery will go straight down.YES it is worst than dynamite.

Answer 12

even if you wanted to make hydrogen why?  Hydrogen is a battery, you take one form of energy, either natural gas or electricity and use those to make H2.  You lose about 50% of your energy in the process, so just use the natural gas or electricity straight up.

YOU cannot add heat to water and make it break into H2 and O2.

Answer 13

The problem is when you convert water into hydrogen and oxygen you lose about 34% of the energy you put in so every time you convert water into hydrogen and oxygen you lose 34%.

But even IF the process was 100% efficient you couldn't move a car. You'd have just enough energy to break the water into hydrogen and oxygen and that would give you just enough energy when burnt to break apart the resulting water into hydrogen and oxygen leaving nothing to move the car.

The First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed. The total amount of energy and matter in the Universe remains constant, merely changing from one form to another.

Basically the best you can do is break even.

The Second Law of Thermodynamics states that "in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state."

That basically means you can't even break even.
