fuel cell vehicles questions

[jeremy]

If fuel cell vehicles only emmisions are water vapors, and if and when everybody in the us has one do you think it will rain more from all the water vapor from the millions of cars that will be on the road. I guess will never know until it happens, just seems like if you have millions of cars on the road only emiting water vapor it might rain more than usual. what do you think?

How are the manufacturers going to generate the hydrogen and oxygen? Correct me if I'm wrong but you get it from the disassociation of water, by electricity. Where is the electricity going to come from?

Imagine if you were to build a powered urban transportation vehicle from scratch, including the fuel . . . would you choose petroleum based on fossil fuels?

All that hydrogen for burining was originally derived from breaking-up water molecules in a strong electrical field. Thus, burning hydrogen returns it to its previous state.

In the USA electricity is deerived mostly from coal, petroleum and nuke.

This is the key question: Which gives better mileage, burning the fuel directly in the car or burning it in a generating plant to dissociate the hydrogen, then burning the hydrogen in the car?

B

Right now, reforming hydrogen is a loss process. However, set up the process to be done through solar and wind power, and the losses would be generally nullified. This type of transformation of course, will not be able to be done overnight either. There's a long way to go before fuel cells become viable.

so I guess nobody knows the answer to my question they should use gasoline and diesel to convert the hydrogen wouldn't that be funny it's like you come all this way in technology and you still have use old resources to make hydrogen.
