Icyball

Icyball is a commercial refrigeration system sold for kitchens without electricity that was manufactured in the 1920s and 1930s. The unit used a single pressure ammonia gas/solution cycle, with no moving parts and allowing any small heater to "charge" the unit. Carl G. Munters and Baltzen Van Platen patented the unit in 1922 and sold the manufacture rights to Powel Crosley.

Though similar devices had existed for decades before this, including a device sold by Ferdinand Carre in 1858; the Crosley IcyBall was the most successful non-mechanical single pressure unit. Units made in the US factory were labeled Crosley IcyBall, while the Canadan produced units were labled Deforest Crosley Icyball.

Snows Of Kilimanjaro Shrinking Rapidly, And Likely To Be Lost
The remaining ice fields atop famed Mount Kilimanjaro in Tanzania could be gone within two decades and perhaps even sooner, based on the latest survey of the ice fields remaining on the mountain .
