Two more Water Powered Cars!

These are different- People usually call the cars that use liquid hydrogen as fuel "hydrogen powered cars". These cars use water as the fuel, and then separate it into hydrogen and oxygen.

It makes it easier for the consumer because water is more easily available than hydrogen.

You really don't get it do you? It takes more energy to produce the hydrogen than combustion of the hydrogen releases. ie. It's useless.

No, as usual YOU really don't get it.
These are research prototypes.
That means more research is being done.
Only a moron makes assumptions about future technology based on limitations of current technology.

I get it just fine Utopian. You know how I said that it takes more energy to split the water than combustion of the hydrogen will release?

THAT'S NOT GOING TO CHANGE

They're called the laws of thermodynamics. You can do all the research you want, but they're never going to change. If it takes 572 KJ of energy to split one mole of water to produce hydrogen, then the maximum amount of energy you can ever get by combusting one mole of hydrogen back to water is 572 KJ. But you will never get the full 572 KJ of work back, because you will always lose some energy due to heat. In effect, it is pointless, AT BEST.

By supporting the idea of a water powered car you are suggesting that conservation of energy does not exist, and that the second law of thermodynamics is bunk.

Not only that, but hydrogen is one of the least efficient fuels (around 20% carnot efficiency I believe), and I highly doubt you can produce enough hydrogen by electrolysis on the fly to power an engine.

You make me laugh Utopian, learn some chemistry.

Come on Utopian, I thought you could tell fact from fiction. Prove me wrong. I'll wait.

Hit the nail on the head, this is about as brilliant as using corn for fuel.

Wait what? Oil doesn't play a role in the ecosystem? Oh good lord...

Just like deep sea steam vents, there is a highly evolved ecosystem based upon oil leaks from within the sea floor. Any high energy source will get consumed by the surrounding environment. There are a slew of bacteria that will even consume highly refined jet fuel.

I am aware that there are microorganism that consume oil but i did not know they had evolved a significant level of complexity. And while that may be true where oil escapes to the surface the vast majority is sealed off from the environment by layers of rock and really doesn't compare with what water in terms of it's role in the ecosystem.

Yeah, this is stupid enough to be up your alley, so I could see you buying one.

No, I'm smarter than you, so I can tell truth from fiction- maybe someday, when you gain the ability, you will actually read the links I provided.

It is a myth, myth busters even tried it.

The tech to break apart water efficiently is not a reality yet. And it still requires energy to break it apart.

"No, I'm smarter than you, so I can tell truth from fiction"

OK, wise one, how does splitting water into hydrogen and oxygen, then oxidizing the hydrogen to water again release energy for running a car?

It doesn't, because there is no net energy release, becuase the two reactions are inverses and thus their free energies cancel out. That's also assuming that the reaction is 100% efficient, which it isn't because of our old friend heat, which means that using water is pointless, at best. So you might as well just use the solar energy make an electric car. That way your efficiency won't suck for shit becuase you're not using a heat engine. Throwing the water into the equation just sucks energy out of the system.

But hey, if you've become so smart that you somehow found a way around the first and second laws of thermodynamics, do tell. If they were actually putting hydrogen into the tanks, this would make more sense, although net net net it's still an energy drain, assuming we have to make the hydrogen gas.

And yes, I read both articles, and had a good laugh all the while.

It actually isn't a reality.

I agree. While there certainly is massive attempts to discredit or bury alternative energy sources I highly doubt that a car that uses solar power to produce hydrogen from water to burn in a combustion engine is viable.

Sweet music. +^'d

there is more behind this idea then a stupid comment....think about it..
