I've been arguing this issue for YEARS. Folks, H2 isn't a fuel, it's an energy delivery tool! This will ALWAYS be true unless somebody discovers some hundred millions of metric tons of elemental hydrogen hiding in plain sight (or at least easy retrieval). Anybody here ever study thermodynamics? Or learned how to analyze SYSTEMS? Even wind, tidal, and solar energy isn't "free." Talk about how "environmentally friendly" these are? WHAT about the effect on WEATHER patterns; you move the place where all of that energy is eventually converted to heat quite far from where it would be if left alone.
