there even smaller versions of these silos, and they are for milk and flour which intrigues me bit. Nice work though. Who do I go for making spigot device I notice you can't see behind the silo if you made that advantage. Oh I am fan of silos and structures, somehow they vanishing even brick types due fact rodents still gain access into silos. I have no idea how in world sun and other measures keep water and milk cool all time. Makes me think they hook up refrigeration to silo in extreme hot weather.
