Don: Interesting material. Is that how hydrogen is produced today, through electrolysis?

How much does it cost? If it is too expensive, then no matter how efficiently a fuel cell uses it, the total cost may be prohibitive.

Can production be ramped up to the massive quantities needed if fuel cells powered by hydrogen take off, or must that await our kicking all the humans out of New Mexico and turning the state into a solar farm first? For that matter, if we have very efficient solar cells, then we only need the hydrogen as a storage mechanism for power that the solar cells generate, when the power is needed at night. Rather than using solar cells to create hydrogen and then run the hydrogen through fuel cells, maybe we could use batteries to store the power instead. Does hydrogen plus fuel cells make more sense than batteries, if the original source of the energy is the sun?

One other comment - you said that natural gas powered fuel cells give off various pollutants. I know that they do emit carbon dioxide, but at a much lower rate would be created by burning enough hydrocarbons to create an equal amount of power. As to oxides of sulpher and nitrogen, I believe emissions from a natural gas fuel cell are either zero or pretty close to it.

Thanks.
