Equation 4 in the above reference should be divided by e (electron charge).
The extension to the case where the cold temperature isnt negligible
compared to the hot temperature is straighforward.
For a cold temperature of 300K and a hot temperature of 400K the voltage
drop in each lead should be around 0.1V.
