Interesting facts: Generations of inventors have endeavoured to construct a perpetual motion machine - and one after the other was disappointed to discover that their designs did not work. Today we know that it is technically impossible to build a machine that works continuously without consuming energy. Apart from wear and tear, a machine only works as long as it is supplied with energy: Electricity, gas, petrol... Without human intervention and practically without wear and tear, the Atmos does not run without energy consumption, but it is fed by an energy source that can be described as "eternal": It draws its energy from the constant fluctuations in air temperature. The Atmos literally lives from the air. In order to utilise the temperature fluctuations as an energy source, a suitable medium had to be found. The choice fell on ethyl chloride (C2H5Cl) - a substance that dentists know as an anaesthetic. Ethyl chloride has a very high coefficient of thermal expansion between 10 and 27°C, i.e. the volume change is particularly large in this temperature range. The round can...
