Consider the amount of energy required to dissociate the 

 gas at the terminals into ions sufficient to carry across the 

 currents. We will suppose that the ions are the same as are 

 produced by X-rays, and that the energy required to produce 

 them is independent of the temperature. This will give a 

 maximum expenditure of energy, since the energy required 

 to produce the ions probably diminishes with rise of 

 temperature.
