>A: None of the above, because they all contribute to world hunger. Agreed. It might be pointed out, though, that it took 1/3rd of the US corn crop being devoted to ethanol for the price of food to affect the lives of people worldwide. That gives a decent feel for the sensitivity of the system to rapid changes in demand. >Ethanol >manufactured from atmosphere processing plants powered by solar energy is >the correct answer. What about algae the produce large amounts of complex hydrocarbons per unit of input sunlight, as the syn biology proposal I mentioned would do. Granted, it's a tough job as Charlie pointed out, but the price of equipment for synthetic biology is falling faster than Moore's law....so there is at least a reasonable chance that something like this could work in 5-25 years.
