My freind just showed me this video. Wonder how it can be incorporated to the car. Pretty cool!

It cant be. Amounts of gas that car electricity can produce are no where near what it needs to work. That and you need more energy to split water than you can get from resulting hydrogen and oxygen.

Paulyy

hydrogen fueled cars aren't new. but are very difficult to get right. do some research on it, Australian universities where working with holden to develop a full hydrogen fueled engine ect ect.

Water will be $100 a barrel if someone figures out how to do it.

Humboldtgrin

Awesome! That would be cheaper then bottled water is now. By a lot!

Using more energy to produce less energy has always turned out not that rewarding.

Humboldtgrin

what makes you think it takes more energy? Did someone tell you that, and you believed it without accual you researching it?

Paulyy

It's been done.
You can run your car on partially hydrogen, but not pure. not yet anyway. gets complicated for pure.

I know a guy who fills up water and petrol, the water gets turned into hydrogen and that gets mixed like a meth injection would.

Maybe 10 years ago, BMW made a variant of their mighty V12 that would run on either straight gasoline or hydrogen.

In H-mode it would make around 250hp, IIRC, around 60% or so of the standard engine's gasoline output since the engine couldn't be optimized to run JUST on H-juice.

Their slogan was "We're ready for the world when the world is ready" (for Hydrogen fuel).

Once 100% developed, hydrogen fueled cars are the future.

Burning hydrogen as a fuel isn't rocket science. But as mentioned it is not efficient to use electrolysis to extract hydrogen just to burn it back into water. It takes more energy to extract the hydrogen than you get back by burning it. It would be far more efficient to just use the electricity to power a motor directly instead.

Humboldtgrin

If you just burn it yes, but if you compress it then what?

JustinL

Then it still burns the finite amount of chemical energy stored in the H-H bond. It's a scam. Laws of thermodynamics don't allow for free lunches. Unless it's a nuclear reaction where E=MC^2 can be used, the amount of energy out will never exceed the energy in.

It was also BS back in 2006:

Nope. You are doing that right now.

Did my research back at school and as Justin said, no free lunch.

Perhaps there is another factor that needs to be discovered or rediscovered to make it work. If you had a solar setup at your house that made hydregen fuel during the day and have wind power setups depending on where you live, or both. Then fill up at home. Maybe it doesn't have to be a device on the car. Perhaps the sun and wind could provide that energy to convert water into separate oxygen and hydrogen molecules.
