On Thursday I will begin a long journey to open source every household appliance.  I am beginning with a refrigerator, because it is the most costly home appliance (aside from washer/dryer).  My half-fridge sized prototype is available now:
http://grabcad.com/library/the-peltier-fridge

I am raising funds to:
-Build 2 prototypes, Half-fridge & Full-fridge
-Launch a Website Resource for Open Source Home Appliances

I welcome collaborators!  Please E-mail me with your skills:

Look forward to the launch of my campaign.  Please contribute if you can.

I have played with Peltier junctions some and microcontrollers a lot. So, I have some interest in your project.

My experience with Peltiers is that they weren't very efficient.  Is this a commercial project?

I would like to hear more.

Its simply not possible to make an efficient fridge with peltier coolers.
Their efficiency is far too low , typical Carnot efficiency for a peltier cooler is 5%
compared to around 50% with a compressor fridge.

I'm not sure about efficiency but If its possible to make ice its definitely conceivable to make an off-grid/portable solar powered fridge that wouldn't be possible with compressors. This is something that I have ideas about. If you make the project completely open source I'm in. I would really like to see if the efficiency of a peltier cooler really gets in the way of making this a reality.
