Icemaker

05/16/2012 2:26 AM

I recall seeing a movie years ago where a man living in a south american jungle built a structure to produce ice. Is this possible? If so, what would it take to make something like that?

Free cold beer, what's not to love?

"Self-Cooling Beer Kegs

An example of a Zeolite ice maker has been incorporated into the Self Cooling Beer Keg. The self-cooling keg contains three chambers. A reservoir of water in an evacuated chamber surrounds the inner chamber containing the beer. This water reservoir is connected by a tube to the outer chamber containing Zeolite. Since this tube is also evacuated it contains water vapor. By opening a valve the water vapor flows to the Zeolite where it will be absorbed. As this happens, the Zeolite warms up, absorbing heat from the water reservoir as it does so. The reaction is sufficiently intense to cool the water in the reservoir enough so that it freezes. After 30 minutes, a cold glass of beer can be tapped and the keg will keep a perfect drinking temperature for at least 12 hours. There aren't any commercially available models of these ice makers yet that aren't rather large and cost $1000 or more. The first viable product is the beer keg($35) but soon will we see other products. If you can chill 5 gallons for 8 hours with no power, they would be perfect for chilled drinks while camping or boondocking."

I'm curious about your inquiry: if you are aware that ice can be produced in structures in other places of the world(not South American jungle), what specifically made you question whether it could also be accomplished in South American jungle? What did you suspect might interfere?

My inquiry was to verify the idea that this operation was possible and not some Hollywood pipe dream. Also, my memory is not as good as it used to be and what I needed was to be pointed in the right direction, and I was with the first reply. Thank you all.

I thought it was Africa, and I especially liked the part where they rebuilt a saltwater soaked outboard and it fired on the first pull. (after replacing the "spark(s)".

Getting back to the question at hand, google Einstein Refrigerator.

After recalling the movie "The Mosquito Coast" you are thinking of, a hell of a lot of pyrotechnics.

we have ice formations year round near the mouth of certain caves in the area.

We make ice 24/7 here in Panama, even in the "remote" jungle. Generally, we use diesel fueled generators to produce electricity to power conventional ice makers...

Absorption refrigeration isn't as efficient as "mechanical" refrigeration, but it works well if you have a free or inexpensive heat source.

Here's a Do-it-yourself version:

http://techref.massmind.org/techref/other/zeolitefridg.htm

And here is a design that is being tested for deployment in the Peruvian jungle:

http://www.google.com/url?sa=t&rct=j&q=zeolite+refrigerator&source=web&cd=3&ved=0CKMBEBYwAg&url=http%3A%2F%2Ffc.uni.edu.pe%2Fmhorn%2FISES2003%2520(solar%2520refrigeration).pdf&ei=2Ze0T4K1NamsjALBj6TSAg&usg=AFQjCNHteBdWOKnqzEZfxVLw_1mMcCyKww

There are also solar air conditioning units that use water as the refrigerant and Lithium Bromide as the absorber, although those require some source of mechanical energy to run the pump that moves the dilute Lithium Bromide solution from the evaporator into the generator, where it is concentrated. This pump is usually powered by an electric motor, but a hand pump or a foot pump might do the job at the cost of a little exertion.

Maybe a self cooling air conditioner for the home is around the corner. I hope so. That would really reduce the electrical load. Then, alternate energy sources would be enough to supply the energy needs for the rest of the house. A home stand-alone energy system may be coming soon without giving up AC!!


Have some fun today,

Though it is not an ice maker but cools almost as much as ice or better. So go ahead and chill your beer without electricity!!

''The pot-in-pot refrigerator or zeer (Arabic: الزير‎) is a refrigeration device which keeps food cool without electricity by using evaporative cooling. A porous outer earthenware pot, lined with wet sand, contains an inner pot (which can be glazed to prevent penetration by the liquid) within which the food is placed. The evaporation of the outer liquid draws heat from the inner pot.

Although the principle behind the device has been known for centuries, one modern device was developed by lecturer Mohammed Bah Abba for use in modern Nigeria and distributed by his company, Mobah Rural Horizons. The device was reinvented by English inventor Emily Cummins in 2006, for which she won a Female Innovator of the Year for 2007 from the British Female Inventors and Innovators Networ as well as a £12,000 sponsorship from NESTA. ''

Here is more about it.........
