Baltzar von Platen and Carl Munters are two young Swedish engineering students with a crazy idea. They are convinced the best way to create a cooling effect is to use heat. They believe so wholeheartedly in the idea that they regularly cut class to work on it. Finally, after many long days and even longer nights, they manage to design a cooling cabinet with no compressor, no moving parts – and no ice. Simply by applying heat to a boiler, a cooling agent circulates in the system, absorbing the heat and thereby creating a cooling effect.
Their cabinet turns out to be the world’s first refrigerator.
