[foodhackingbase] [Tastebridge] [Noisebridge-discuss] how to build up cold room - cooling system tips

[Tony Longshanks LeTigre]

Miloh posted an article quite a while ago, maybe a full year? about a group
that had built a cooler that required no electricity using 2-liter soda
bottles & little else I believe. Did you see that? Maybe Miloh can dig it
up again or you can find it in the archives.
