I found out, while reading the list of Make‘s 2010 Green project contest (won by Global Village Construction Set) that Mikey Sklar (the off-the-grid DIYer of Thruth or Consequences) not only has stages ideas about messing with his body or LEDs, but also wanted to rationalize the biggest energy-wasting appliance that resides in every US home: the fridge. he replaced it with a much small chest cooler, regulating the temperature with a DIY controller, packing it with boxes and putting the unecessary stuff wher it belongs… on the shelves.
