Alvin Weinberg passed away at 91, and this is an obituary we should note. The man was into nuclear energy following his work on the bomb, but when the first energy crisis struck in 1973, he was one of the people that had the wide vision to look also at renewables. Oak Ridge became the first D.O.E. lab to have teams working on biomass, solar, geothermal… and above all on energy modeling and energy policy as such. I visited the lab in my Hudson Institute days, and saw right there the work on tree plantings and the studies on ethanol. I had contacts with Oak Ridge staff regarding the use of ethanol in Brazil and even learned new things from them about the work on oil shales in Brazil. They were ready to listen to the ethanol-for-octane arguments when these were a “no go” with the Washington establishment. They acted as an energy Think tank. This was thirty years ago. There was also a liaison office in Washington DC. They were looking at coal gasification and coal liquids. Al Weinberg was someone Herman Kahn would call up to talk things over with. My point is that reading Alvin Weinberg’s obituary, please do not think that he was just nuclear.
