Crimeny. Other nations ARE involved. China and Russia are recalcitrant but what else is new but even there the light bulb is beginning to come on. Now to the ignorant statements: a scam for governmental control!? How? And, more importantly, why? Occums Razor pal. As for the petroleum-fired engine, are you kidding? Nobody, nobody sees that as the future; the only question is how best to generate and store the electricity to run the electrics. Way cool stuff happening there. But you hit the nail on the head; research. So why is the energy industry pouring tons of money into swaying public opinion away from what 97% of the scientific community has no doubt about, instead of using that money for researching high-capacity storage methods, wave generation, wind generation, and solar? Because they have a lot of money invested in hydrocarbon exploration and extraction, that's why.
