Abstract: A fluid moving apparatus includes an electric motor having a rotor and a stator and a propeller. The rotor rotates relative to the stator on an axis to generate a rotational output. The rotational output is provided to the propeller to power the marine propulsion apparatus. The stator includes one or more coils configured to power rotation of the rotor. The one or more coils extend circumferentially around and can be coaxial on the axis. A portion of a housing of the motor extends into the aquatic environment to facilitate heat dissipation.

Abstract: In accordance with one or more embodiments, a surface wave launcher includes a launcher body configured to surround, at least in part, a transmission medium. A planar antenna includes a first antenna element, a second antenna element and an aperture, the first antenna element and the second antenna element having first portions on opposing sides of the launcher body and second portions on an aperture end of the launcher body, wherein the second portions are perpendicular to the launcher body and the transmission medium and wherein the planar antenna is configured to transmit and receive guided electromagnetic waves that propagate along the transmission medium without requiring an electrical return path. A reflector, configured to direct transmission and reception of the first guided electromagnetic wave to and from the aperture, is electrically coupled to the conductive launcher body on an end of the launcher body opposite to the aperture end of the conductive launcher body.
