He did mention water injection along some fault lines as being a problem. I'm not really sure of the science, but if you must mock, at least do it for what he said. I am aware that water expands in volume by a factor of 1400 times when it converts to steam and could see how it might affect geothermal faults.I would like to question the cost structure presented as concerns natgas v. coal. These figures must leave out the cost of the fuels. I worked many years at a plant that had two 500mw coal units and two 500 mw gas fired combined cycle units. Although the gas units had it all over the coal units in operational flexibility, energy efficiency, and ease of operation; the cost of fuel made the coal units cheaper to run.
