The extra peltier, by itself doesn't weigh much. But when you add in the extra heat sink, fan, etc etc, it adds up. It could be self-defeating to double up on those items. On the other hand, a second peltier, side-by-side with the other one could be made to share a common heat sink and fan. BUT another word of caution,. These peltiers draw between 3 and 4 amps each. By doubling up, you could cause a statewide brownout.
