So your telling me that 1 single leaf contains more chemical energy than natural gas, biomass, batteries, etc etc??? Get real man! Your pretty smart but your ego gets in the way of reason sometimes. Your not hearing anything I'm saying because your just trying to one up me lol Nowhere in my post do I state that H2+H2O are a reaction. Where are you getting this??? Your still not understanding my point that man's ingenuity = Orville and Wilbur flying the first airplane and Neil walking/breathing oxygen on the moon. Geez your thick.
