"Everything starts as somebody's daydream. And, when you're daydreaming, it is science fiction. It's when you start work out how you put it together, true science fiction becomes real science."

| Hovercraft | ||
| A vehicle that moves about on a cushion of air. |
Obviously, Gibson did not invent the hovercraft; but I like his description.
| Feeling entirely dislocated now, Komiko watched as Sally made a survey of available vehicles, quickly bribed a uniformed dispatcher, intimidated three other prospective fares, and chivied Komiko into a pockmarked, slabsided hover craft, painted in diagonal bands of yellow and black. The passenger compartment was barren and remarkably uncomfortable-looking. The driver, if there was one, was invisible beyond a scrawled bulkhead of plastic armor. The nub of a video camera protruded where the bulkhead met the roof, and someone had drawn a crude figure there. |

The first known design for vehicle using an air cushion was by the Swedish designer and philosopher, Emmanual Swedenborg, in 1716. The craft looked like a small boat turned upside down. The operator of this vehicle would "flap" a pair of oar-like air scoops, forcing compressed air beneath the hull. However, the inventor soon realized that the energy requirements were greater than a person could provide.
The name and concept of hovercraft were created by Sir Christopher Cockrell; the first working hovercraft was built by him in 1959. Hovercraft are today in common use; however, dreams of hovercars and other vehicles never came to fruition, owing to the excessive power requirements of getting a vehicle to "hover" on anything but the smoothest surface.

For an amusing look at an intelligent (?) hovercraft, see the entry for hover-limo - hovercraft for hire from Steel Beach by John Varley.
