But upon closer inspection, all that’s at work here is some clever engineering tricks. The unit is essentially one of Dyson’s vacuum cleaners working in reverse. The gray base station sucks up air and forces it through the circular blue thing that sits atop the rig. When the air jets through the front of the circle, it creates a suction behind and to the sides that draws more air through the loop and makes the fan more powerful. Dyson claims the Multiplier increases pressure15-fold and spews 118 gallons of air every minute.' Gallons? Get with the programme and use SI units! Oh well, still looks amazing."
