Crucial to my comfort on a hot and steamy Boston summer evening is my Dyson Air Multiplier. It uses a motor that sucks in air through the vents in the base, sends it up the column of the machine and out a very thin slot around the edge of the circular piece at the top. The air is blown out over a piece of plastic shaped similarly to an aircraft wing, which accelerates the air and draws in surrounding air, resulting in 15 times the airflow than what is sucked in at the bottom. Pretty cool!
Of course the Dyson Air Multiplier is extremely sleek and futuristic, making it a feature of my dorm room rather than an eyesore like typical box fans.
