Intelligence is created by a process not too different from a Firestorm (A firestorm is a conflagration which attains such intensity that it creates and sustains its own wind system) – and maintained by controlling the fire. Since consuming energy to ensure future consumption is the only job of a neuron, consuming it does. I think it (energy consumption) goes up to one forth of all you’ve got when you do really thinking. i.e. the most intelligent.
The whirls and branches of firestorm allows it to spread around very aggressively. So if you know how to control energy supply, the physical process of complex energy delivery to be a Firestorm is a hell of a model. Well, where is a fire – there is hell, – another good metaphor for intelligence.
