Air Conditioning Technology was Predicted 100 Years Ago John Elfreth Watkins, an American civil engineer, wrote an article in the year 1990 making predictions about what the world would be like 100 years later and some of them, in fact, have actually come true. The article was published by the relatively unknown engineer in an American women’s magazine, which was titled, “What May Happen in The Next Hundred Years”. Many of his predictions were accurate including, air conditioning, mobile phones and digital colour photography. His visions and prediction for the future would seem almost unreachable at the start of the 20th century. Watkins anticipated ready meals, for the average life expectancy to rise to 50 years old and the innovation of television. Although many households have digital thermostats, the visionary predicted the concept of air-con which would regulate the temperature of the house by turning on hot or cold air. Not all of Watkin’s predictions and prophecies were correct though, as he thought that flies and mosquitoes would be exterminated, that there would be no more C, Q or X letters in the alphabet and that everybody will walk 10 miles a day.
