Dear Crispin, you are quite right about the lessons from the past. Some of them are billions of years old. I cite here the example of the methanogenic archaea. They have ability to extract oxygen from their substrate, so that they can convert sulphate into sulphide, nitrate into ammonia etc. One of the fantastic things that they can do is to convert carbohydrates having relatively low calorific value into hydrocarbons, having very high calorific value. Is anybody working on emulating these organisms to produce hydrocarbon fuels from abundently available carbohydrate like cellulose? Yours A.D.Karve
