No he isn't, that's comprised in the price (if you use the correct value of 1.48V that is). What's the energy needed to go from water to the gases? 1.48V, times the charge of the transferred electrons (1 electron per hydrogen atom). Of course, you get the same energy when going the other way. Michel
