Mine was pulsed operation for that very reason. Two minutes on, three minutes off seemed to be a good timing setup, but it's certainly not empirical. I didn't have to reverse the polarity of the peltier block; the weather was hot enough. Again, though, you're missing my point - I'm not saying I did the exact same thing they did, but it was based on the same principles. There's no way I'm the only one who's done it, either.
