cooler

A while ago, I proposed a strawbale cold house, split in half, with one half filled with water barrels that were allowed to freeze, and the other half for cold storage.  A fan would move air through the insulated partition wall as needed.  The barrels would be frozen by running a fan from outside air during the winter.

However, according to one source even a partially filled barrel will bulge and fail.  I'm not impressed by the thought of three high stacks of round bottom barrels either.
