Abstract

A vehicle usable in the air, on water, or on ground is described. Outer wing portions are connected to a central portion by a mechanism which allows the outer wing portions to pivot about first axes for placing the outer wing portions in stored positions. The outer wing portions are also rotatable about a second axis for placing them in positions whereby they are useful as sails for driving the vehicle without the use of an engine. The wheels are capable of being pivoted to non-positions.
