Nice little post but it's wrong to say that Refrigerators and Air Conditioners break the second law of thermodynamics. According to the second law of thermodynamics, the heat never flows from a cold body to a hot body spontaneously. Refrigerators and Air Conditioners do transfer heat from a lower temperature to higher temperature but they require external work. The entropy change is also positive in these machines, so they don't violate the second law :)
