Apparatus for propelling fluids, crafts and harvesting fluid power comprises a spherical body 130, having a convex leading surface and a concave trailing surface. Upon oscillation, the spherical body 130 accelerates and ejects ambient fluids to impart a propulsive momentum to the apparatus and attachments thereto. Apparatus is secured to a motive power source directly or via actuating member 132, by fastening through aperture 134. Apparatus can be operated directly by a reciprocating motive power source, and by the reaction momentum imparted to a supporting base. Rotary to linear motion converters can also be used to drive the apparatus. Thrust may be vectored by rotation of the spherical body 130 about a base. Drag reduction using fluid dynamic shapes, fluid phobic materials and a lubricant cavity are embodied. |
