Hydrogen can work as a means of energy storage, but you can't use water as a fuel. Water is the product of the oxidation of hydrogen, and has essentially zero potential chemical energy. You can split it with electricity to get hydrogen and oxygen again, but you have to add a lot of energy to do that. Check out:

The Straight Dope: Can you really get better gas mileage using your car's engine to make "Brown's gas?"
It was not meant to be taken literally.

What i am trying to get at is that we can create hydrogen fuel with water and electricity.
Sure, it takes a lot of electricity but with the combination of solar, wind, and hydro power (all of which are relatively clean and 100% renewable) we could make driving our vehicles almost 100% emission free.

Its just going to take a lot of money and further research to get the ball rolling for the everyday consumer.

Most steel engines have a thermodynamic limit of 37%. Even when aided with turbochargers and stock efficiency aids, most engines retain an average efficiency of about 18%-20%.[7][8] Wikipedia
As you can see, there is no such thing as 98% effeciency in the ICE. If you could achieve even 40%, you'd double your fuel mileage. Brown gas does this:
It adds some combustionable fuel and with it's chemical make up, facilitates complete burning of the parent fuel, all this for an initial investment of around 3-5 hundred bucks. The average improvement varies somewhere around 20-50% improvement in fuel mileage. If you commute 20-50 miles a day, this may be beneficial to you. If like I you may go 2-3 miles from your home once or twice a week, then the benefit would be minimal at best. BTW, if anyone disbelieves the fact that the oil companies could and have made people with these stellar ideas disappear, you are fooling yourselves. Do I have proof, of course not, or I'd be disappearing along with them.

Trust me, I'm an engineer, and this so-called technology is bogus. The explanations use 'common-sense' arguments that are understandable by the average person, but they omit plenty of important details. For instance, everyone knows that you can hook an alternator up to your engine, and if it spins it will generate electricity. Intuitively, the engine is big and generates a lot of power, and the alternator looks small, so it seems to use an insignificant amount of power. But one detail that seems to escape these "water-powered car" sites is that the more electrical load you hook up to an alternator, the harder it is to turn. This makes the engine work harder and use more gas, in a way that isn't insignificant at all.

Look, all i was saying is that it is possible to run your car off a fuel derived from water.

Do we currently have the technology to do it efficiently?

No.

Will we never have the technology?

No.

I'm saying we need to be putting more $$$ into the research of an emission free renewable source of energy.

This global demand for Oil is killing the economy, and the environment. We NEED to do something

Being an engineer, seems you'd do a little research on this before commenting so negatively. I'm no engineer, but it makes sense to me that if you are adding combustible material (I've seen this with my own eyes, it makes a big bang) and the chemical make up of the combustible also helps the complete burning of the parent fuel, (Gasoline or Diesel), you would have to increase the efficiency of the ICE, translating to more power and more fuel mileage. The most amperage a v-8 unit draws is around 30 amps. Most modern V-8s have 100+ amp alternators and the driving load varies around 10-40 amps, depending on the type of stereo or day or night driving.
Bear in mind, modern car alternators can put out as much as 1.5Kw (1,500 watts) and can account for as much as 3 to 5 BHP load on your engine! - an extreme example perhaps, but in a car with heated seats, heated windscreen, heated rear window, heated mirrors, ABS, quad HID lighting, air conditioning, etc. etc. you can begin to see how power can get gobbled up without your even being aware of it!
So 30 amps may take 3-5 hp, but you would be gaining much more than that, 20-50% in fuel mileage as compared to 1/2-3% of drain on mileage by the parasite of a loaded alternator. It's not much more than driving with your lights on.

See, this is the part that probably tripped you up. Water by itself doesn't combust; water is the product of combustion. You can make flames come out of water by adding energy, but you're still losing energy overall. For instance, you can put sodium metal in water, and it will burn, but you're adding chemical energy in the form of sodium. You can split water with electricity and then burn it, but you're still adding energy in the form of electricity. You can bombard salt water with microwaves and get the water to split into hydrogen and oxygen, which will burn, but you're still adding energy in the form of radio waves. In all three instances, you're adding more energy than you're getting out.

Of course, I might be misunderstanding something. Because of the law of conservation of energy, you can only get out what you put in. So if you split water via electrolysis, then burn the resulting gases, where does that extra energy come from? You seem to think it comes from more complete combustion of the fuel, but in modern vehicles, combustion efficiency is very high, much too high to gain more than about 1% from increased combustion efficiency. Practically all of the wasted energy is in the form of heat, but there's no mention of actually using this heat in any way. So I still have to ask, where does the additional energy come from?

yes, and my point is we can create electricity virtually emission free. We can not produce oil emission free. Or burn it.

This is about the environment, not the almighty greenback.

You're right, we can create hydrogen virtually emission-free. However, storing that hydrogen for use in vehicles is the hard part. The pressures it would need to be under are immense, and even liquid hydrogen (which is the densest it can be compressed to) is only about as dense as styrofoam. One alternative that I think is pretty interesting is converting hydrogen and CO2 to methanol. Methanol is a liquid at room temperatures, and it can be used in fuel cells or internal combustion engines.

Of course, we had been talking about generating hydrogen within a vehicle, which would not be practical to do with hydrogen, unless you plugged your car in at night.

To compress hydrogen to higher pressures than it can physically be compressed to? Technology can't do everything. And pretty much every material we can make tanks out of would weigh much more than the fuel inside it if it were designed to withstand that pressure. It's not impossible, but there are other technologies that are more promising, like methane-powered vehicles or plug-in hybrids.

I was just trying to differentiate between what medicineman was talking about and what you were talking about, not trying to say you were wrong. Still, it would be more practical to charge a battery than it would be to generate hydrogen via electrolysis.

I'm not looking for practical. I'm looking for emission free.
Batteries die out in the long run. Then they go to the dump where they leak toxic acids into our beautiful mother earth.

I ride a bike, thats A LOT less "impractical" than a hydrogen powered car. But, 100% emission free,:hump: unlike gasoline, methane and ethanol.
Battery power is emisson free but the battery cells are bad for leaking their pollutants in our mother earth.

We can create electricity emission free (solar, wind and hydro), and we can use that electricity to split the combustible atom Hyrdogen from water to create energy! Energy that is non-polluting!

First, it'd be more practical to develop non-toxic batteries for use in electric cars or plug-in hybrids than it would be to build a hydrogen-powered vehicle.

Second, the best-performing batteries use lithium, which isn't toxic. Heck, it's found naturally in spring water and it's used to treat bipolar disorder. They are expensive, but they're doing a lot to bring down the price.

Third, it wouldn't be hard to implement a battery-recycling program. If electric cars were widespread, it'd be inevitable.

Fourth, CO2 emissions aren't a problem if the carbon comes from the environment. After all, we all breathe CO2 out when we exhale, and every other living thing emits CO2 as well. If we can pull CO2 out of the atmosphere and combine it with hydrogen to make methanol, that would be carbon neutral, and essentially emission-free.

Finally, just about every source of electricity pollutes at least a little. Wind turbines use tons of steel and concrete, which is made from iron ore and coal and limestone. Putting them up requires a lot of fossil fuels too. Dams too, require a lot of concrete and steel. And don't even get me started on solar; the pollutants from processing silicon (used to make solar cells) are some of the worst there are. Of course, these are all significantly better than coal, but if you're looking for emission-free electricity, you'll never find it.

I don't think that is a proven fact. You can speculate that with substantial reasoning, but I don't believe it is a proven fact.
Besides, we CAN find the technology to make hydrogen practical, efficient and reliable.

Second, the best-performing batteries use lithium, which isn't toxic. Heck, it's found naturally in spring water and it's used to treat bipolar disorder. They are expensive, but they're doing a lot to bring down the price.
Again, something I do not believe to be 100% true. Lithium may not be bad in the concentrates it occurs naturally in spring water, but the concentrate in man-made batteries will be many multiples of that. That could EASILY be bad for the environment.


Third, it wouldn't be hard to implement a battery-recycling program. If electric cars were widespread, it'd be inevitable.
Exactly how do you "recycle" used toxic waste? And i thought you said Lithium was non-toxic?

Fourth, CO2 emissions aren't a problem if the carbon comes from the environment.
Hmm, this comment is slightly foolish.
Carbon dioxide is carbon dioxide. One atom of carbon two atoms of oxygen. there is no difference in where it comes from.
however, CO2 isnt necessarily a horrible thing. As us growers know, plant foliage takes the carbon out of CO2 to form more foliage (as most living matter consists mostly of carbon, including your skin) and realeases the pure oxygen.
CO2 can be countered by our environment.

But only so much, and right now, we are producing WAY MORE than our environment can replenish.


Finally, just about every source of electricity pollutes at least a little. Wind turbines use tons of steel and concrete, which is made from iron ore and coal and limestone. Putting them up requires a lot of fossil fuels too. Dams too, require a lot of concrete and steel.

But all of this does not even come close to the environmental damage burning fossil fuel does.
You build a turbine and it is built. One shot deal that will produce emission free electricity for many years. Same with the dams and the solar panels.

I did not previously know about lithium being non-toxic. Interesting. The lithium battery cost will go down as electric vehicles come into widespread use. Just as battery recycling will increase, as you say. Hopefully all recycling will increase.

As far as mainstream appeal, the biggest hurdle for electric is range followed closely by comfort. Air conditioning is a huge draw on power when all you have are batteries for the vehicles energy source.

Fourth, CO2 emissions aren't a problem if the carbon comes from the environment. After all, we all breathe CO2 out when we exhale, and every other living thing emits CO2 as well. If we can pull CO2 out of the atmosphere and combine it with hydrogen to make methanol, that would be carbon neutral, and essentially emission-free.
Bio-diesel is carbon-neutral, too.

Easy to forget that all those green options must be developed and manufactured under present conditions. But it's a long road and we must start somewhere with the hope that emissions can eventually be limited as much as possible.

Well, there are a lot of problems with hydrogen. At the extremely high pressures it has to be stored at, you'd essentially have a bomb strapped to your car. It isn't very good for powering internal combustion engines, so we'd have to wait until fuel cell technology caught up. If fuel cell technology evolved to the point where we could use it to power a car, then hydrogen would be more practical, but until then we need to look at other technology that's in the less-distant future.

Again, something I do not believe to be 100% true. Lithium may not be bad in the concentrates it occurs naturally in spring water, but the concentrate in man-made batteries will be many multiples of that. That could EASILY be bad for the environment.
If you ate a lithium battery, it would probably be bad for you, yes. But our bodies can easily eliminate it, so it doesn't build up in our system like lead or other heavy metals.

Exactly how do you "recycle" used toxic waste? And i thought you said Lithium was non-toxic?
They do it all the time in industry, since pollution standards are a lot higher than they used to be. It's certainly possible to reclaim useful stuff from toxic waste. But as for lithium batteries, there are plenty of good reasons to recycle that have nothing to do with toxic waste, after all, lithium is valuable and we wouldn't want to throw it away right?

Hmm, this comment is slightly foolish.

CO2 can be countered by our environment.
Not foolish at all. There is a certain amount of carbon circulating in our environment. Plants take it out of the air, and other living things put it back. The problem with fossil fuels is that using them increases the total amount of carbon circulating in the environment, which then increases the amount of CO2 in the atmosphere. It slowly makes its way out of the environment as it's buried in sediment or in peat bogs, but we're adding it faster than it's removed by a lot.

But all of this does not even come close to the environmental damage burning fossil fuel does.
You build a turbine and it is built. One shot deal that will produce emission free electricity for many years. Same with the dams and the solar panels.
Solar panels don't have a very long lifespan. 30 years if you're extremely lucky. And with their level of pollution, they're far from being a clean energy source. Dams have a very good lifespan, and wind turbines are somewhere in between. But still, all of these have finite life spans, so every time they're rebuilt, they pollute the environment, which means they don't produce pollution just once, but every time they're built.
