It stumbled around this today:

http://www.keelynet.com/energy/waterfuel.htm

And I thought it was very interesting, and woudered if anyone has thought about trying something like this. It seems to be a very basic setup, all you have to do is get your engine internals ceramic coated and ceramic coat your exhaust system or convert to stainless steel. I would reallly like to see a suer rotary achieve even what they claim at least 50mpg ... they say anywhere from 50-300mpg. Imagine the money you save ... oh and maybe a few trees ...

No. Basically, there is no way to make it work like that. You are talking about energy from nothing, basically. Perhaps you could suppliment the gasoline under certain conditions to help emissions and possibly mileage, but that is about it. They talk about adding power, but in general, hydrogen lowers power. Of course, even a big tank will only hold a very small amount of hydrogen in terms of mass if the hydrogen is in its gasous state. If it was so easy, you would see eveyone with hydrogen/water powered cars. They even say that the plans may not work in the disclaimer.

It would be nice to have something like this, but physics prevent it for the most part. Water is a stable molecule and takes a lot of energy to break in into hydrogen/oxygen. You spend more energy breaking the water than the energy you will get to drive the engine/alt. Now, it may be possible to take energy while the car is coasting downhill or braking and using that to produce hydrogen or some other good way of storing energy that can be used later.

i could never justify putting that much time and money into converting, when the only confirmation of it working is a website online that iv never heard of.

i also think if it was that great that it would be available from some manufacturer like geo who has nothing but fuel efficiency in mind

there's a video of it on www.youtube.com ... search water energy that where i first saw it today.

This is all wrong in many ways, to give you an idea -- It takes 270 BTU of energy to produce 1 mole of Hydrogen, which has 230 BTU of energy available (looks like we are already going backwards!). The 270 BTU would come from the alternator which is being driven by the engine. Even a 25% efficiency is optimistic for the process, but that would give us an input requirement of 1080 BTU now, to get back our 230 BTU worth of Hydrogen. Of course when we burn the Hydrogen we are at best going to get our 25% efficiency again, meaning we get only 57.5 BTU of energy out. So at best what we have done is use 1080 BTU of energy to produce 57.5 BTU of energy, just about a 100% waste of our time (and $3.00 gas) to do so. Looks like a great way to REDUSE gas milage, not increase it.

If you want to use another source of energy, like the energy dissipated during braking, why not just convert that into electricity, which will be much more efficient that all of the Hydrogen crap to start with (hello Prius).

Trees are a renewable resource. Cut as many as you need.

I still think that if hydrogen could be produced from water using something like solar or wind power, than it could be a viable source of fuel for cars.

Sadly though, the current method of producing hydrogen is by using fossil fuels to create it.

and there are storage systems that take hydrogen and store it by binding the Hydrogen molecules to an solid, so there is no need for high pressure storage tanks.

The problem is it is easy to do a demonstration running at idle for a short time. The question is: Can it be sustained? Physics says no. The one guy says he can run his car off of the hydrogen, but is using gas/hydrogen hybrid. If it will run off of hydrogen alone, why doesn't he do it?

Anyway,one guy was saying 4oz of water per 100miles = 3200 miles/gallon. The other was saying cross-country = 22 gallons (say 3200 miles with 22 gallons). I am not sure where the large difference in their "calculations" come from.

If there was a way to make the hydrogen as you drove, that would be best. One of the biggest problems with hydrogen is storage. You need to use a lot of energy to compress to its liquid state to get a good range. The tanks are big/heavy for the amount of fuel and hydrogen leaks through pretty much everything (steel included).

Currently, hydrogen is derived from methane. You could use wind/solar to make it from water, but it isn't very efficient. You would be better off just using solar/wind to make electricity. There are new nuclear reactors that are being deisgned. A few are being designed for very high outlet temperatures (900 C+). These high temperatures could alllow for these nuclear reactors to crack water molecules to make hyrogen (similar process as to how hydrogen is made with methane now). It takes very high temperatures to really make this work.

Steam engine, carb wont work, gotta keep in pressure. talking no accerleration. DC water, no problems.

Get trainsimulator 2006 , get in the steam locomotive. oh yeah, fun! valve after valve, pressure. steam is made.


But dude, hydrogen cars are gay. theres no pollution from gasoline cars.

no pollution from exhaust at all. its not even proven, its a therory. weve got hundreds of thousends of years for oil.

Synthetic oil and everything is now.

you wanna know what hydrogen and natural solar cars are!

im guesing they have made there products different causing diff calculations

but did you see the vid of him with a garden hose constatly pouring water with the motor still running.....

there useing simple electrolises(spelling) couple table spoons or acid and water
to tell the truth when i was in new zealand i made one it actually worked pretty good(creating hydrogen) but.. i never actually riged it up there idea using a vaccum source on the carb was awsome it created a way better reaction(i have no clue why) but it was cracking

damn hippies though, all we can do is smack them.
