  Mistaken Observations

  Pete,
  As has been stated many times in this series, AGW is not the only driver of climate change during the last 100 years. It is important to remember that the majority of anthropogenic CO2 has been emitted in the last 20 years. The integrated emission of CO2 from 1940-1979, while or course higher than in previous years, cannot be characterized as "soaring" in light of what has happened since.

  Please refer to the following entry (and graphs therein) in this series related to mid-century warming:

  Power Problem

  Besides the large temperature gradient needed for efficient heat extraction (which you can get anywhere if you drill deep enough), and an efficient thermal exchange at those depths (which you might get by fracturing rock), you also need a larger enough heat flux from below than the rate at which you are extracting it.

  The typical heat flux towards the earth surface is .06 watts per sq. meter--much smaller than the solar energy flux. To generate 1 MW of power, you would need to collect 100% of the geothermal energy over an area of 6.4 square miles. That's a lot of deep drilling.

  Abundant energy does not equal abundant power.  On Geothermal energy posted 3 years, 3 months ago 7 Responses
