Nice idea ffx6! I am not sure if a regular freezer will be able to freeze an antifreeze/water mixture but that is definitely a good idea if you can get it to freeze. Thanks for sharing!

But there is a cost involved in freezing a gallon of water a day in the freezer

0.00143567 cents p/day Council Water Rates

Make sure you mark any bottles with anti-freeze in them as POISON, because one swallow of anti-freeze'll kill ya!
