However, it can push a massive amount of air forward every second and ensures a smooth air flow within the room, LiveScience reports. Since more than 200 years ago, when the first fans appeared, little changes have been made to its base design, mostly because everyone considered that the device merited no improvements. But Dyson has invented the Air Multiplier technology, which ensures that his fans push as much as 119 gallons of air out every second. It is a massive improvement, when compared with 19th-century Middle Eastern fans, which were powered by streaming water and a !
