The Miracle of ICE from HEAT


Ingenious application of simple principle of physics turns the flame of a gas jet into ice cubes in the non-mechanical refrigerator.
By ROBERT JOHN BAYER
TO THE average man there is nothing mysterious in mechanical refrigeration.
He knows that gases and vapors lose heat in expansion and that by a repeated cycle of compressions and expansions, confined gases can be cooled to an extent where they will operate as refrigerants. He knows that, in his domestic mechanical refrigerator, there is a motor and a pump which compress the refrigerant and that its repeated expansion in the coils in his box produces the cold that freezes his ice cubes and preserves his foodstuffs.
