Hydrogen fuel cell from water?

Question

many people say that you can use any type of water to convert it to hydrogen, including salt water. there is one way to save earth from sinking from the polar ice caps, and that using the heck of the coastal waters instead of the inland water. water is water is water. anybody agree?

Answer 1

I agree.  Offshore wind, tidal and ocean current turbines can provide the electricity to do so and the hydrogen can be sent via pipeline onshore.

Answer 2

Most vehicle hydrogen generators use distilled water with a little baking soda to assist the electrolysis, but regular tap water works good to.  Most cars/truck's electrical system generates 12 to 15 volts at 30 to 60 amps.  Applying 12 volts at 30 amp to stainless steel electrodes, one can generate approx. 1/2 to 1 liter of HHO gas of which is directed to the intake an used a supplemental fuel.  Most vehicles can see an increase in gas mileage of 25 to 50 % depending on the degree of detail of the installation.  Safety features such as bubblers and flame arrestor are installed and modification to the O2 sensor and MAP to allow a more lean response from the computer.

By utilizing energy being generated from your vehicle anyway, provides an excellent opportunity for fuel economy.

Answer 3

No.  Look, to separate the hydrogen from water you have to use energy. when you burn hydrogen and oxygen, it then recombines to form water again. You cannot get any more energy out o fthe reaction than you put in--in fact, you lose energy because no system is 100% efficient.

Therefore, if you are talking about these so-called "cars tha trun on water"--its a scam, pure and simple.

If you are talkig about the legitimate efforts to devvelop hydorgen powered cars--those can work. But they are almsost certainly never going to e viable as a major eans of everyday transportation. Not ecause they won't work--because we already have some thing better.

Here's what I mean. You have to either extract hydrogen from oil (tha'ts where we get it now because its too expensive to seperate out water and hydrogen. But using oil as a source gets us nowhere--either in terms of the environment or the economic issues of energy dependency on foreign oil--we're right back at square one.

Assuming you do find a cost-effective way of seperating hydrogen from water by producing enough cheap electricity (which is required). Why bother. Its cheaper and simpler--and more energy efficient--to jst charge batteries in an electric car.   You really don't need to use a hydrogen fuel cell at all. It just makes to the system more complicated than it needs to be.

Answer 4

I still think that hydrogen fuel cells are a strong viable alternative to the energy issues we have going on today. I agree that these new technologies are expensive and have efficiency issues but with time things will improve and get better. We have to also think about what kind of emissions these technologies provide. I am a fan of fuel cell tech!

Answer 5

the only need the H2O not the other thing in that water
