The 2008 film does not include hydrogen generators as a transition technology. Hydrogen generators with computer modulators can make existing vehicles, furnaces and power plants more efficient for the rest of their working lives. 10 or more MPG should be available to all vehicles especially those with flex -fuel design as the cheapest fuel can be used without deterioration of performance or mileage. Much less carbon emission in existing vehicles would be the benefit for the next 25 or more years. Catalytic converters get cleaned out with the hydrogen supplementation. Hydrogen should make coal plants have less of their worst emission - coal ash. Present coal ash is 4% carbon. Higher burn temps and fluidized bed combustion fueled by hydrogen should make combustion more complete. Coal plants should be able to reclaim much more of the heavy metals which have commercial value. Transition technologies are being ignored in the present conversation about environment.
