The 12-fan Wall of Wind (WOW) at FIU is the largest and most powerful university research facility of its kind and is capable of simulating a Category 5 hurricane — the highest rating on the Saffir-Simspon Hurricane Wind Scale.
Pretty cool.
The 12-fan Wall of Wind, is powered by electric fan-motor units and controlled by two variable frequency drives. The Wall of Wind was funded with a combination of private and public funding and came at a cost of approximately $8 million.
