The Air-cushioned Vehicle that Travels Clear Out of Sea and Land
The air-cushioned vehicle is not an airplane, since it does not have wings.It is neither a ship nor an automobile, since it travels clear of sea and land.It has a conventional gasoline engine, but no wheels.How does it travel？What keeps it in the air？
Under the air car is an air chamber with a large propeller parallel to the ground.The gasoline engine supplies power that causes the propeller to whirl.This fills the chamber with air.Some of the air is forced toward the ground through tiny holes around the edges of the car.
These air jets create a wall that keeps the air from escaping from the chamber.As more and more air crowds into the chamber, the molecules of air become compressed.Their pressure becomes so strong that it lifts the car off the ground.
Once the car is floating, the driver releases some of the compressed air.This makes the car speed forward.
