Many of us are struggling to work out our positions in relation to global warming as well as to how we replace energy generated at present by coal-fired power stations. A couple of US professors wrote a paper for Scientific American in November last year called “A Path to Sustainable Energy” in which they claimed that the science and engineering suggested that it was possible “to re-power America with 100 percent carbon-free electricity within 10 years.” It was duly published and read by millions. How many woke up to the fact that it was a spoof is not clear, but Howard Hayden, Professor Emeritus of Physics, University of Connecticut did. It’s worth reading his report here.
I’ve never known a problem in science or technology on which the “truth” was so difficult to ascertain.
