You are in the Hydrogen Fuel Cell Cars Forum. Your Host is pf_flyer
| hello, i am a student from Guatemala and im doing my graduation project about alternative fuels and how would they affected our enviroment... according to what i had investigate alternate fuels would actually benefit our enviroment, but then i saw this forum which said otherwise. I needed to do some interviews to professional people about my topic, but here in Guatemala there are not professional people that can answer the type of questions im asking. As i see, you guys are professional and really know what you are talking about so i would really aprecciate if you could answer some questions for me.. if anyone is interested please tell me so, so i can give you the questions i need you to answer. thanks! | |

Without getting into the issues of whether the production of hydrogen, the fuels used building the vehicles, etc are worse...I have a simple question. If the output from a car running on fuel cells is only water vapor, has anyone looked at whether massive new amounts of water vapor will impact the atmostpheric conditions? I know it probably sounds silly at first blush, but for a long time, nobody ever thought a little bit of carbon emissions would have any impact. If you take all current car owners' future emissions as well as the vast amounts of future emissions coming from China and India, I wonder if that additional water vapor would have any impact. One of the things that makes me wonder is a study I'd heard about based on data collected on the days following 9/11. IF I understood it correctly, the researchers showed that the clouds created by the vapor trails of the jets in the air on any given day actually reduces the amount of sunlight reaching the earth in a small, but significant way. Granted, there doesn't seem to be any harm done, but if we add millions of cars pumping out water vapor...would it add to the effect? Just curious... |

The energy required to produce the hydrogen and lack of an infrastructure to deliver it make hydrogen a real work in progress once you start to look at the realities.

Replying to: pf_flyer (Nov 06, 2008 10:00 am) I got to thinking about what someone posted saying that it is impossible to keep hydrogen contained of a long period of time. I may not drive my car for a week at a time. Does that mean I would get into my Civic Hydrogen car and find my hydrogen had all leaked out? I am thinking that the ethanol in our gas evaporates also. Supposedly the systems are air tight. Does that prevent all evaporation? |
