Original poster: "by way of Terry Fritz <teslalist-at-qwest-dot-net>" <BA1ELECTRONICS-at-aol-dot-com> hi all, why not think of using a pelter junction---- the sold state cooling module. you could epoxy the COLD side to an ammo bucket. use 3 or 4 of these, they run on like 12vdc , no moving parts. cheers, bart avery
