A device for generating a pulling, or drag, force. The device consists of a single large track, powered by a power source located on a bottom wall above said track; of which the power source is an electric or combustion engine, mechanically connected with a multitude of rollers. The device additionally consists of an elongated handle with a generally t-shaped or generally u-shaped distal end so as to be received and grasped by a human user. Additionally, side walls and an optional front and/or overhead wall may be utilized to protect the power source from the elements.

The invention relates to a control bar for grip, traction and control of a traction unit which has the control means of the control device, steering, acceleration and possible elevation and descent integrated into the structure thereof, the control means able to be thumbwheels, push buttons, pressure sensors, a gyroscope, a joystick or any combination of the same, or electronic processing means that allow for voice recognition. It also has a control unit and another communications unit (either connected by wiring or wireless) as well as its own power supply integrated in the support structure or received from the traction unit.

An underwater propulsion system is disclosed comprising a foot board with one or more battery-powered propulsion units. A throttle control system may be enabled in the foot board such that a movement of the user's foot controls the throttle. Flattened Lithium batteries allow thin lightweight construction of the foot board. Use of trolling motors as propulsion units provides thrust advantages over pre-existing underwater scooters.

The invention is directed to a graspable human propulsion device comprising a primary pole, a lateral pole affixed to the fore end of the primary pole, and a ducted fan assembly affixed to one end the primary pole and configured to accelerate airflow along the longitudinal axis of the primary pole. A user wields the graspable human propulsion device by grasping the primary pole with a first hand and the lateral pole with a second hand. The graspable human propulsion device acts to propel the user along the direction in which the longitudinal axis of the primary pole is pointed. This device is intended to be utilized by a user mounted on a personal transportation apparatus, such as a skateboard. In one embodiment the user controls the amount of thrust by use of a throttle lever mechanism. In another embodiment the user controls the direction and amount of thrust by use of a knobbed slide potentiometer. In a third embodiment the user controls the direction and amount of thrust by use of a twist throttle mechanism. The graspable human propulsion device of the present invention provides a conveniently balanced, easily wielded, and enjoyable propulsive experience for the user.

The present disclosure provides a snow transport system with a frame comprising a base plate, a pair of opposed side plates mounted on opposed sides of the base plate, and a plurality of cross members extending between the side plates. A pair of convex lower track slides are mounted on lower portions of the pair of opposed side plates, and a pair of convex upper track slides are mounted on upper portions of the pair of opposed side plates. A drive wheel is mounted at an upper front portion of the frame, and an idler wheel mounted at a lower rear portion of the frame. A continuous track is wrapped around the drive wheel, the convex lower track slides, the idler wheel and the convex upper track slides. A motor assembly is mounted within the frame, and connected to the drive wheel through a transmission assembly. A push arm assembly is mounted to one side of the frame, the push arm assembly extending forwardly from the frame and having a push bar portion and user controls at a forward end thereof.
