Abstract: The ideal design for a redundant orbitally driven electric ducted fan that can replace a family of current propeller and motor combinations in electric ducted fan designs by meeting air flow and pressure requirements while drawing less electric current to rotate and thus produce the required flow not only would reduce cost of operation over the life of the fan but opens new possibilities for electric powered vertical takeoff and landing vehicles with redundant drives improving safety of operation. The entry of flying machines using propellers and lifting fans such as hover bikes and quadcopters, manned or unmanned is driving a need to re-examine the application of force applied to rotate these fans to achieve a reduction in aircraft weight and increase flying time for a given battery charge or load of fuel.

Abstract: A portable, pontoon-type watercraft includes a pair of pontoons interconnected by a pair of cross members to maintain the pontoon members in spaced relation. The bottom surface of each pontoon member defines at least one concavity for providing increased stability to the watercraft by increasing surface tension between the water and the bottom surface of the pontoons. A number of internally threaded metallic sockets are integrally formed into each of the pontoons to allow various components and accessories to be mounted thereto. The pontoons are formed of a lightweight, semi-rigid material and define a hollow interior that can be pressurized to provide internal support to the walls of the pontoons. The seat includes a yoke section that can be slid over the neck and shoulders of the user and handles that can be grasped by the user to facilitate transportation of the watercraft from one site to another.
