Has anyone got an Einstein refrigerator? |
I heard that A. Einstein, in addition to being a physicist, also
designed a refrigerator with no solid moving parts.
Does anyone know if there is one around?

Check out Wikipedia under "Einstein Refrigerator". This is basically
the old Servel gas refrigerators designed with a gas ammonia cycle
more or less like the patent by Einstein and his student Leo Szilard.
These things have no moving parts and last for absolute EVER! There
are probably STILL some of them around still working from the 1930s.
They ran on gas (city gas to your house, not gasoline). Today you can
still buy them. Even those that run on kerosene or propane as well.
The old ones weighed a TON though and the parts of the old ones were
steel which can eventually rust and fail. I'll bet you can STILL find
a bunch of them around any large city. Get off your butt and search
the Internet. I'll bet you can even find some for sale! Wouldn't you
like to own a 500 pound "Einstein Refrigerator"?

Without researching the Einstein refrigerator (I believe the
Scientific American article is around here somewhere) I am suprised
that the Einsten-Szilard concept is equivalent to that of the
Servel. Great!
A currently available version of a no-moving-parts refrigerator is
the Dometic http://www.dometic.com/templates/fp.aspx?id=488
"The basics of Dometic’s current operations were laid as early 1922
when the two Swedish students, Carl Munters and Baltzar von Platen
invented absorption technology."
As a trailer puller, I have owned three of these. (At different
times.) They are great for camping.
I don't plan to research the heritage of variations for absorption
technology, but if you are interested and do so, please post back.
