Hydrogen Fuel

The hydrogen car's hype is based on no pollutant emissions.

The two types of hydrogen cars would be internal combustion hydrogen and fuel cell hydrogen, the latter of which is more efficient. For a fuel cell car, a traditional engine won't work and electric motors are needed.

A fuel cell is like a battery with hydrogen on the anode side and oxygen on the cathode side. It's also, unlike a battery, designed to be constantly refreshed. Once electricity is derived from their reaction, the electric motor changes it into mechanical motion and water vapor is released.

The biggest problem in the development of hydrogen engines is where to derive the hydrogen. It's not a primary source, only an energy carrier, and has to be manufactured from hydrocarbons which in turn on an industrial scale would probably produce more pollution than cars with combustion engines. However, what you've quoted suggests a new source for hydrogen fuel, though I am skeptical the little soy bean will solve all our problems.

Also, fuel cells are as of right now far too expensive for Tom, Dick or Harry to buy, and all cheaper ones can't seem to endure driving.

As far as hydrogen in rockets, I believe liquid hydrogen and liquid oxygen are in a mixture for rocket fuel, but I'm not sure. I think some submarines already use hydrogen as well, but I can't tell you a thing about that.

Here are some links to Hydrogen Fuel web sites you might find informative.

thanks both of you for the answer. ahh, probabily i have got the point.
you have explained very nicely. from your commnet , its clear now that hydrogen fuel will be helpful for the mankind because it is pollutionless. yea, you are rightly pointed out 2 problems------

1. source of hydrogen is a problem

2. In order to produce hydrogen fuel from raw material or hydrocarbon for the large demand of the people the producer industry may produce pollution itself...thats not good.

Anyway, sir, i found in a article that type of quote. may be the discovery is in a child stage. may be we need galons of soyabeans to produce required amount of hydrogen fuel...but who knows what will happen in future !

Anyway, Thank you sir. its nice talking to you.
