Comment: Hydrogen-based fuel cells are not the answer to our energy needs.
Water, although pure and natural and all, is (in its vapor form) one of the most effective greenhouse gasses on our world! CO2 *is* a huge problem and *must* be stopped; but replacing it with substantial amounts of H2O vapor will be even more devastating.
In our zeal to address a very real problem, we must not act so hastily as to replace one problem with an even worse one.
