In order to explain a physical process the mathematics that has been developed to describe it must be a good representation of all of the steps. What Dr. Spencer has done with his article, ‘Yes, Virginia, Cooler Objects Can Make Warmer Objects Even Warmer Still‘ is to take the basic Stefan Boltzmann equation (SBe) that I described in my previous article and neglected to consider the changes required in the adjustable parameters, with the exception of T1, by his addition of the second plate.
Dr. Pierre R Latour has already pointed out errors by Dr. Spencer in Latour’s ‘No, Virginia‘ rebuttal. The full email exchange between Spencer and Latour may be studied here.
Without a doubt the energy flux to the container from the heated plate will change. The A and ε are no longer the same as before the addition, and have to be included inside the bracketed part of the equation, with a corresponding time dependent variable as the emissivity and temperature now become a function of time. Note that T2 in the SBe is neglected in the picture presented to attempt to describe the effect.
Following on in his discussion Dr. Spencer boldly asserts that “back radiation” is occurring although nowhere in the illustration is any evidence as to how it is possible.
