A chain reaction by definition requires a positive feedback loop. Just because something is that hot does not mean it has the ability to become hotter when you add "Earth." It certainly could ignite all the oxygen in a localized area, fuse all the metal in the building, and light all the forests within miles on fire, but thats pretty much it. Also 550MW/h / <efficiency factor of the water turbines> is by definition the most energy that will be present at the site and thus the total energy capable of being released at once. I'll make up a number and say the turbines are 10% efficient. So we have 5.5 GW/h of power available which is around the amount of energy released in a hurricane in 1 second. http://en.wikipedia.org/wiki/Orders_of_magnitude_(energy) http://en.wikipedia.org/wiki/Orders_of_magnitude_(energy)
