I hadn't actually considered doing that.I expect this means that you will now run off to B W Hill to try to get an answer
Here is a good BWHill quote, though:
The Etp Model is predicting that the end of the oil age will come about as a result of the entropic decay of the world's petroleum production system. The advantage of the method, over other estimates of world reserves, is that results are calculated from the world's accumulated production data set. It is based on data for which we have reasonable knowledge, as opposed to projected conjecture, as to what might be existing reserves.
The Model is derived through the solution of the "Entropy rate balance equation for control volumes"; which is a very well known equation in thermodynamics. It is the only model known that can generate quantitative results from a proven thermodynamic law. Because the Model is a mathematical construct, its validity, or rejection can only be subject to an analysis of its construction. Even though the Model has been reviewed by thousands of qualified persons from around the world, a reasonable refutation has not yet come forward.
As the output of the model does not bode well for a long term continuation of the present industrialized system, it is to be expected that many opinions will run counter to its conclusions. Opinions are, however, highly influenced by emotional interpretations, and are subject to a bias that results from those emotions. Historically, decisions that have resulted from emotionally driven conclusions, have often ended very badly!
