The sad thing is that the greed of the oil, coal and auto interests in this country and those that feed off of them has prevented any meaningful leadership in R&D for alternative energy sources for more than 3 decades. I remember the terse report on an experiment with geo-thermal energy said something about the sediment rich water clogged the pipes making it an impractical source of energy. The joke used to be: Why aren't we using more solar power? Because the oil companies don't own the sun or haven't figured out how to bill for sunlight. We will pay for this. As the African proverb goes, "When elephants battle, it's the grass that suffers." In 1969 or thereabouts, the Smithsonian Magazine had an article about the limited supply of fossil fuels and what we needed to do to prepare for the time when they would be in short supply and cost more than we could imagine. Nobody wants to hear about that. Image what a curse it would have been to be shown something from the future like AIDS or the Holocaust and not only not have anyone listen to you, but to have them shun you or threaten you with imprisonment if you did not stop making a pest of yourself and upsetting people.
On a spring afternoon in 1955, the high school I was to eventually attend burned. I was a little kid not yet 5 standing in the street watching the smoke far away, not knowing what was burning. Years later, one of my best friends told me about that day. The motion picture projectors had been blowing fuses all day. After school was out, this young student who had a reputation as sort of a flake and a teller of tales came running to my friend who was head of the HomeEc Department yelling that she had to get out of the building because the school was on fire. She tried to shush him but he would not be silenced and begged her to go with him to see it because no one would believe him. She agreed after assuring him he would be in big trouble if he was not telling the truth. He took her to a door of the gym and when he opened it, one whole wall was was in flames. People don't want to hear about the unthinkable or even the inconvenient or unpleasant.
