Fast-food fat--future fuel for cars
February 8, 2007
Maybe its the fact that I have built stand alone computers(that are in control of fueling on very powerfull street cars), but hydrolysis is not too difficult to understand. Someone just needs to take the time and spend the money to do it.
In simple terms, if you take a postive charge and a negative charge(think putting jumper cables in a thin pool of water) and put it through clean water(read distilled, aka rainwater) the Hydrogen and Oxygen seperate. The oxygen is not flamiable by itself, but the hydrogen certainly is. If you were to measure the amount of voltage required to split the proper amount of molocules up(voltage required for amount of water) to generate enough hydrogen to get sucked into the combustion chamber(or set out through the current fuel injector) and could get the alternator to generate enough current to charge the battery and still provide enough energy for hydrolysis, you would have a car that runs on water.
Most people will try to tell you some reason why it doesnt work. Such as the water freezes in the winter(easily solved by haveing a plastic "fuel"(even though its water)line with a small pull from a seperate battery so the water never freezes). However, I gaurantee you if someone paid for me to survive the way I do now(pay mortgage every month, dog food, food, etc), I could give you a car that runs on nothing but water. The only "tricky" part of the whole thing is to start the process which can be done just fine with todays batteries (since the today's batteries move the starter as it is). The simple fact of the matter is, if someone generated this technology it would never hit the mainstream because it would destroy the world economy.
If you do a search you'll find someone that has a 1990 ford wagon running on nothing but water. HOWEVER, the he struck a deal with the goverment to put the technology in the hummers for war purposes. This whole green thing is just a lie to prevent someone doing what will eventually happen and that is give the technology away for free(which i eventually plan to do). SOrry to ramble, but people are just getting really foolish about it.
Its MUCH easier then people think
My Tahoe is better to the environment then any water burner or hybrid. Look up why.
Here you will see a lot of information and hopefully a bit can help people understand a little better. Water vapor, according to scientists, is not controllable by humans. Not to mention that our ozone is made of N2 and O2, so adding more oxygen cant hurt that bad. Even if you were to have every single car on this planet running on water, it sitll wouldnt make a dent in the ozone. In fact it might help balance the negative "equation" out.
infrastructure is already there with the gas station. Instead of filling
with an explosive gas just compressed air. No transportation of
flamable gases and the water saved could be use for whatever. The
energy saved by not having to make hydrogen could be used to
clean the air of CO2.
One problem, with nothing to tax,would income taxes have to go
up?!!!
"Gaseous water represents a small but environmentally significant constituent of the atmosphere. Most of it is contained in the troposphere. Besides accounting for most of Earth's natural greenhouse effect, which warms the planet, gaseous water also condenses to form clouds, which may act to warm or cool, depending on the circumstances."
- we should all reduce emissions!

- Air compressed cars will be great but in the mean time we can all do our part. has anyone seen ed begley jr.'s piece anout reducing your carbon footprint? it's pretty simple and doable. http://www.oneforthetable.com/oftt/articles/reducing-your-carbon-footprint-in-2008.html
