Does anyone remember the "Osocool"? It was a metal box covered in Plaster of Paris with a "well" at the top. You poured water into the well and it drew the heat away from the metal box. We used one in France in the early 1970's, and it coped with very hot weather. I haven't seen them mentioned anywhere.

Do not recall them . But it is a simple heat exchanger. Take a sock , soak in cool water , place a beer can in it , tie it some where outside , half an hour later , one chilled can .
I was desperately looking for an Easicool (same type as Osocool) on ebay for ages. Finally got one a while ago, but can't get the thing to work at all. I know they work better when the weather is really hot, and we haven't had much of that the last couple of summers, but even on the odd hot day I still can't get it to cool at all, even though I've followed the instructions to the letter. I must be doing something wrong, or I've got a dud Easicool
An Easicool won't 'cool' as such, but it will keep cold things cold! Before you use an Easicool for the first time each season, or when it's not been used for a while, sock it in a bath of cold water to make sure the 'core' is wet - it won't work at all if the core isn't wet through. Never put anything into it that isn't cold, and they work better in the sun (make sure you keep the water topped up).
My parents had an Easicool instead of a fridge for years - they took the cold food camping in a cool-box with freezer blocks. Once the Easicool was set up, they transfered the cold food and the freezer blocks to it - the blocks cooled the inside of the Easicool quickly. Once cold, it stayed cold. And an Easicool with never cool beer, wine or fizzy drinks - stick them in the fire bucket instead!
Thank you so much Scampi (oh darn it, my smileys aren't working!).
There was nothing in the instructions about soaking it in a bath of water. I just put the water in the tray, put refrigerated milk inside it & expected it to keep the milk cool - it didn't! I'll get the Easicool out again now & try it again after it's had a bath :-) hehe!
Have always improved the ability of a normal cool box to keep things cool by soaking a towel in water and draping it over the top. Leave it outside the tent, ideally in the shade and also in a breeze. (Think about how cold you feel in wet clothes out of the sun and in a breeze).
My parents also had an "Osocool" in the early 70s, and we bought a more up-to-date version a few years ago, just as they were stopping regular manufacturing. I remember the Plaster of Paris-like material seeming to work better than the present core, but perhaps I am mistaken. After priming our Easicool in the bath overnight, I use a frozen 2pt bottle of milk as an ice pack to cool the food, including an unfrozen bottle of milk for our cup of tea when we arrive at the campsite. We find that the Easicool works well within its limitations - it won't cool the food, but protects it from the heat - and wouldn't be without it. Instructions on the door advise running cold water over food packs before they are added to it.
when i was in the scouts we had a metal box that u sealed and you place in a river, the cold water from the river cooled the box and the stuff inside stayed cool.
I come from Africa where we used an evaporative meat-safe aka large parrot cage with burlap sacks thrown over, which we kept wet. Remembering how very effective these were ( we could even freeze stuff on a hot day) I made a small version for my tiny, hippie van. I used a small, domed, plasticised, front-opening cat carrier and sewed a burlap sack to cover it with a roll-up flap over the door. I sit it in a tray which collects excess water and can be filled with water which courses up the burlap, keeping it wet if we're away having fun. It is super cold and light. It has a handle which makes it portable ( you can put it in direct sunlight if you want it close to freezing, ) it needs no electricity and you can pack stuff in it when not in use. It's a brilliant bit of kit.
My camping days are long past, but I remember putting milk etc in a large polythene container, standing it in the washing up bowl with water, and a wet towel over the top to act as a wick,
Happy days!
