Icy-Ball

I don't know where exactly to post this, but I've been trying to come up with a alternate to ice in the cooler---and fell upon Powell Crosley--famous for the Crosley Radio, the Cincinnati Reds, WLW, and the sheet metal engine. One of his other products was a kerosene refrigerator unit called the Icy-Ball. It was a batch absorption unit using anhydrous ammonia and water as the working fluid and was marketed to the nonelectrified America before WWII. After the war, Rural Electrification pretty much made the Icy Ball obselete, but in the non-electrified world of boondocking in a small trailer--it could be time for a rediscovery.
I found a fair link on the process for non electric refrigeration that leads to a source of plans (for $15.00), but it is old and in Florida. Just kinda wondering if:
a) any one remember using these units and;
b) any Floridians know of this place ---Dunedin, FL
Rap
