Just remember you need energy to get Hydrogen (Score 2, Insightful)

And that would most likely come from electricity. One of the most prevalent sources of said energy is coal burning power plants. Now, I know that there are a lot of dams that provide us with power too, but those also have costs. The Northwest has only recently come to realize that putting dams on rivers threatens fish, etc. If there is some vast reserve of pure hydrogen that someone can find, then great. But until then, these fuel cells simply shift the pollution to the site of the power plants. Please don't get me wrong, I love the idea of driving a car with a fuel cell sometime in the future; or even using the Coleman generator in my house. Truly great would be using a solar panel array to split the water, then using the result to feed a fuel cell later. Peace (first post! yay!)
