Is there a company that produces these devices today. If not where can I get the plans to build a home coling system.

Wasn’t this the type of cooling used to make ice in the book (and movie) “The Mosquito Coast”?

The design is indeed interesting and useful.
I would like to know if it has been further developed for engineering and regular production either in the U.S.A. or elsewhere. If so, I would like to have the details.

I am Adoko,residing in Nigeria where I studied electrical engineering.
I will like by way of curriosity request for a compressor,the type displays in this cover page.I mean a compressor which uses thermo to circulate or pump gas.
I will be most greatful if you can react on this inquiry as soon as you can.
Thanking you in advance for your cooperation.

There was a portable version of this built called the Crosley IcyBall – no doubt you’ll see it in one of your magazines.

The IcyBall, rather than being heated by the Sun, was boiled in a bucket – this drove off the ammonia inside from the ammonia/water mixture. PLacing it in service (half in and half out of a freezer box) allowed the ammonia to recombine in the mixture, causing the temperature drop.

Solar versions as above are still built in tropical countries – they’re not all that complex and very effective where electricity is not available and cooling is needed.
