Hover cars were really big for a while in the sixties, especially in remote places like Dustville Oklahoma and Cornpone Nebraska.
You could buy a hover car kit from the Sears Roebuck catalog and convert your dad’s clunky, four wheeled car car into a smooth riding cruising machine.
They work on the principle of reverse-osmotic, magno-gravitation pull. Once activated they would hover indefinitely.
While the hovering part worked great, there wasn’t a good propulsion system. Propellers proved to be too risky and jet engines made them go too fast.
Most hover cars were simply pushed to get them going. Once started they would glide endlessly assuming there were no trees, buildings or rock walls anywhere nearby. You couldn’t stop or steer them.
Some hoverites (as they like to be called) experimented with using oars and others tried sails. The results were always the same. They’d crash into something and explode. After a while Sears stopped selling them.
The reverse-osmosis, gravitational-pull engines rely on levitationate, which floats away as soon as it’s mined. It’s all gone now.
Pretty soon almost all the existing hover cars had exploded, ending a sweet little chapter in automobile history. Occasionally you can find oner in an old barn or a back alley, still hovering.
Don’t play with it though. they are still highly explosive and will blow you away.
