Hi Folks,
After reading all about Dry Ice, I am going to stay away from using it.
I am going to try and find one of those 12 volt coolers, add a solar panel to the cabin roof, and see if that might work.
My brother who use to sail cat boats would freeze milk cartons of water as his ice for the weekend. As the ice melted, he would drink the water.
Fred

We have done this for years, in square-ish containers, (better for packing) and in flavors, (Cool-aid or Crystal lite). Works great, but wait to start drinking until the bottle is 2/3 to 3/4 thawed, (better for flavor and cooling efficiency)

I keep my cooler outside, too. In warm weather I cover it with a white towel and I keep the towel soaked with water. The evaporation keeps the outside of the cooler cool.
Also, when using dry ice, put it on top and keep it dry. Water 'melts' it quickly. I think that's in the instructions you get sometimes. |

I can't recall which brat did this but someone glued the one inch reflectorized foam insulation available at Home Depot or Lowes to the inside of the top of their cooler and reported a significant gain in ice keeping. Their reasoning, I think was that the top is where most external heat comes from. Depending on size you could do that all around the interior.

Here's another idea from Moose (Al) that the above post reminded me about:
(This is in regard to keeping ice longer for preserving fish, but would work just the same).

What we have done is to take an Extreme cooler and line it with rigid foam, cut on a bandsaw and glued together with silicone adhesive, to add extra insulation, such that the resulting space just accomodates four blocks of ice. Then we duct tape the cooler shut, put a cinch strap on it for good measure, and wrap the whole thing in a space blanket. Then when we get where we are going we stash the cooler in a shady place on an island. About half the ice disappears in that amount of time.
(Second paragraph of unrelated information deleted).

it's all about insulation and temperature gradients. I had a large ice chest I lined with 1.5' foil backed styrofoam and a tight lid of same, essentially and ice chest in an ice chest, with dry ice inside it would last many days, including 100+ degrees of Sacramento heat. I also used to use the dry ice (thankfully from work) to super cool 3/4 full bottles of gatorade (air for expansion of frozen water) and use as both super cold ice, and my drinks. Have to go slow so the plastic bottles didn't crack, and went through a fair amount of dry ice.
