ABSTRACT

Melville Beardsley. Cockerell had the idea that a vehicle would float on a ring-shaped curtain of air. He proved it with experiments using two empty coffee cans and a hair dryer. Crowley, meanwhile, was inspired by his discovery that a household lampshade could be made to float on air. In 1957 he built a hover-chair, which was not unlike a giant lampshade. He and Beardsley separately came up with the invention of a flexible skirt to stop air from escaping beneath the ACV. This escaped air had been the chief weakness of Cockerell’s design.
