Diver propulsion devices and methods of propelling the devices and divers upon and beneath the sea are presented. A diver propulsion device is comprised of a wing buoyant in water, an electric motor propulsion system, a leash interconnecting the wing and diver, which leash may integrate control circuitry of the motor, photovoltaics atop the wing, and, batteries, each electrically connecting the motors, fins attaching the wing provide hydrofoil flight stabilization, and foot constraints attaching a deck of the wing. The wing is a hydrofoil, and the diver stands and lies upon the deck of the wing, and, during hydrofoil flight, the diver is substantially above the sea and the wing is seaborne. In hydrofoil flight, the device may be motor propelled, or, by the diver heaving and pitching the device, or, by both methods simultaneously. Undersea, the device tows the diver by motor power energized photovoltaically, and, or, by battery.
A diver propulsion device having a deck upon which a diver may stand and kneel and lay, the diver propulsion device comprised of:
A method of propelling a diver propulsion device for hydrofoil-flying a diver upon the surface of a body of water and for diving below the surface of the body of water and towing the diver under the surface of the body of water, by a diver situated upon a deck of a wing of the diver propulsion device, the diver propulsion device comprising the wing, the wing having a wing-span, a wing-chord, and a wing-thickness and, wherein the wing-span approximates a height of the diver and the wing-chord approximates a shoulder-width of the diver at a center of the wing-span, at least one electric motor propulsor, a leash interconnecting the diver and the diver propulsion device, and an electronic control circuit operable by the diver to control a thrust output of the at least one electronic motor propulsor, the method of propelling the diver propulsion device comprising the diver making a selection from the list of the following:
A diver propulsion device for hydrofoil-flying a diver upon the sea surface and for diving below the sea surface and towing the diver under the sea, the diver propulsion device comprised of:
