(DOPE SLAP) Well...looks like my inexperience is really showing!!! I was reading this COMPLETELY wrong!! For cooling it is a Peltier Effect, for power generation it is a Seebeck Effect.

So for this model: 12711-9M31-24CW (200?C rated)

The COOLING rating for a 60C temp difference requires 24.0 amps / 226.1 watts / 15.2 volts.

The POWER GENERATION rating is 5.23 amps / 22.5 watts / 4.30 volts @ a 200?C Hot Side & 25?C Cold side temp difference. Sure does look like at least 3 would be needed to do much.

Dang!! Now I understand...thanks for being patient with me everyone!!
