The typical human being standing on floor exerts a pressure of about 3 lb per sq. inch (20 KPa), and that will increase to 25 lb per sq. inch (172 KPa) when walking. In contrast, the common hovercraft exerts a pressure of only 0.33 lb (2.2 KPa) per sq. inch - even much less as speed increases. Fans generate air pressure that lifts a hovercraft. Many large navy and industrial hovercraft often use as many as six elevate fans and two thrust followers. Fans inflate the cushion contained inside the skirt beneath the hovercraft to provide elevate and in addition they provide thrust, which propels the craft forward. It is vital that a provision be made for buoyancy so the craft will float on water.
