oh dead thread i have moved the rock before your tomb. "car of the future" ... come forth!
i found what i feel to be an excellent un-biased look at the reality of hydrogen fuels, and hoped that it might reopen a discussion that i have an extreme interest in. i also learned something i didn't previously know about hydrogen fuel. the PEM (proton exchange membrane) fuel cell was invented in 1839. hydrogen is by no means a newly discovered fuel source.
here's something i wanted to point out:
At present, 95 percent of America's hydrogen is produced from natural gas. Through a process called steam methane reformation, high temperature and pressure break the hydrocarbon into hydrogen and carbon oxides — including carbon dioxide, which is released into the atmosphere as a greenhouse gas. Over the next 10 or 20 years, fossil fuels most likely will continue to be the main feedstock for the hydrogen economy. And there's the rub: Using dirty energy to make clean energy doesn't solve the pollution problem-it just moves it around. "As a CO2 reducer, hydrogen stinks," Romm says.
but what i find disturbing about this is in the following paragraph. in an effort to stem the tide of co2 emissions:
Capturing that carbon dioxide and trapping it underground would make the process more environmentally friendly. In July, General Electric and BP Amoco PLC announced plans to develop as many as 15 power plants over the next 10 years that will strip hydrogen from natural gas to generate electricity; the waste carbon dioxide will be pumped into depleted oil and gas fields.
if the thought of that doesn't absolutely terrify you, click here for why it should
anyway ... here is the link to the popular mechanics article. lots of really good information in here about the reality of using hydrogen as a fuel source: http://www.popularmechanics.com/technology/industry/4199381.html

You're like a fountain of information that noone cares to know. XP
