From ice boxes to space-saving marvels, here's how the refrigerator became the modern appliance we know and love.
The company was purchased by Frank Gibson, a competing manufacturer of "ice refrigerators" in the early 1900s. It was the largest in its industry at the time. In 1931, the company began making electric refrigerators. [1] During the Second World War, Gibson manufactured 1,078 Waco CG-4 troop and cargo assault gliders under license.
In the cooling step on the inside of the refrigerator, the g state particle absorbs energy from ambient particles, cooling them, and itself jumping to the e state. In the second step, on the outside of the refrigerator where the particles are also at an e state, the particle falls to the g state, releasing energy and heating the outside particles.

The industry saw significant growth post-World War II, with the introduction of dishwashers and clothes ...
The Einstein–Szilard or Einstein refrigerator is an absorption refrigerator which has no moving parts, operates at constant pressure, and requires only a heat source to operate. It was jointly invented in 1926 by Albert Einstein and his former student Leó Szilárd , who patented it in the U.S. on November 11, 1930 ( U.S. patent 1,781,541 ).
