My first thought is after all the oil is gone… Or maybe when it’s too late to make an impact on global warming? Take the electric car for example. The auto industry and oil companies didn’t have a monopoly on electric cars, so they had to go away. Even though the infrastructure required for hydrogen will be many times more expensive to build then electric, and it will take many years more until we can see hydrogen fuel cell vehicles operating on our roads. I’m afraid by the time these vehicles are widely available, it will be too little, too late. We could be making a difference everyday with electric vehicles today. Unlike hydrogen fuel cell cars, it’s a technology of today, not tomorrow. And you could charge an electric car at home…How easy! Unfortunately, the auto industry and the oil companies wouldn’t make money that way.
