I don't follow trends in that world, so maybe there've been some dramatic improvements in Peltier device efficiency. However, previous posts here from folks who've worked with them have indicated that Peltier devices aren't going to cut it for any kind of cooling beyond those small beer coolers, or computer chip cooling. I suggest you check the archive (http://www.evdl.org/archive/ ). Entering peltier at the search prompt returns a LOT of hits. Around 15-20 years ago, Bill Dube' built an ingenious passive cooling system for his controller. He put an evaporator on the controller and a condenser in the Wabbit's cowl, and filled the system with (IIRC) butane. Maybe something like that would help.
