Well I didn't beleive it when I first saw and I'm still not sure.:S
The Einstein refrigerator is a type of refrigerator co-invented in 1926 by Albert Einstein and former student Leó Szilárd, who were awarded US patent 1781541 on November 11, 1930. The machine is a single-pressure absorption refrigerator, similar in design to the gas absorption refrigerator. The refrigeration cycle uses ammonia (pressure-equalizing fluid), butane (refrigerant), and water (absorbing fluid). The Einstein refrigerator is portable, made of inexpensive, nonmoving parts, operates silently, and is very reliable. However, leaks of ammonia can be dangerous.
Einstein undertook this invention as a way of helping along his former student. He used the knowledge he had acquired during his years at the Swiss Patent Office to get solid patents for the invention in several countries. The refrigerator was not immediately put into commercial production, but rights to use the patents were sold to companies such as Electrolux of Sweden, and the funds obtained supported Szilárd for several years.
