Get out with your ancient trash.

Yet again:
The only real way to use water as fuel is to use electricity to separate it into hydrogen and oxygen and then have the hydrogen and oxygen react with one another, liberating heat and additional water. No matter how well you design such a mechanism, you will never reach 100% or >100% efficiency on your electricity input. So basically it comes out to being an electric motor.

wot about cold fusion? wot about that?

So what's wrong with a purely electric, charged car? Assuming efficiency is present and the car is competitive for commuter standards of speed/carrying capacity, what's the problem?

If this guy has it nailed down so you can fuel up on whatever that stuff is, then you won't need to wait overnight for the car to charge.

Yes, electricity would be required to initially set-up the gas(?), but it takes oil out of the picture. And oil is the hang-up. We can generate electricity miles away however we want to.

Possibly physically impossible. Even if it weren't, we have no idea how to do it. Even if we had any idea how to do it, millions of small hydrogen bombs zipping around on the roads and occasionally crashing into one another would be a very bad idea.

The pure electric vehicle would be vastly more efficient and perhaps more importantly has already been done. See the EV1 and the documentary "Who Killed the Electric Car?" for more info.

That's all very well and good. But 90% of electricity is generated using fossil fuel power stations and if we all used electric cars the power stations would have to produce that much more energy and burn that much more fuel.

In places like Iceland (where 99.9% of electricity is produced using renewable geothermal sources) it is reasonable. But most other places would see minimal benefit (a small benefit, yes, as power stations are more efficient than car engines but nothing major).

I never realized that electric-car technology was that close. If this is less efficient, then it assuredly has some use....somewhere. Welding? I'm no expert, although as I understand things freshmen chemistry majors are the people to go to.

Anyways, we may be stuck in this rut of gasoline-powered cars for a while (as long as it's profitable for the oil industry), but electric cars are the way to go (I have no idea how the stuff in the vid works, but I'll take your word for it).

Wait, so we need to improve our cars and our power plants?

Hold on, don't get too far ahead of yourself! We might start a chain of global cooling!

It's always fun to see people who failed at elementary school chemistry get all roused up by stuff like this.

part of the problem is that americans don't have chemistry till high school.

On the contrary. It might force people to actually learn how to drive.

Thats what I was thinking, at first we'd still get the same amount of crashes with a few explosions and then there would barely be any explosions at all.

Terrorists approve this car.

Got bored, did some random googling...

Supposedly, there exists a method to modify your car's engine to include an electrolizer (fed from the car battery) that produces hydrogen gas that reacts with the gasoline/air in the tank to produce a finer mist which increases fuel-efficiency.

Now, I'm not sure what happens to the original oxygen in the water.....if everyone used this, I have no idea if the oxygen levels in the atmosphere would increase enough to make things dangerously combustible. Thoughts?

Edit: ye olde pirate ships seem intent on not using the oceans around them to fuel their boats, ye have been warned.

Thats a pile of dung. The amount of electric to convert a 4 cylinder car is less then most 9v batteries. Its not alot of current. Not at all. You could tape a cluster of flashlite batteries together and do it. Its actualy super efficient. The problem with that tech is not current, lack of knowledge or anything like that. The problem comes from the high moisture content in the fuel. Most modern motors dont like water. They dont last very long when using this tech. Other then that big oil has made great strides to make sure this tech is never researched.
