Abstract: An oscillating linear compressor includes a cylindrical chassis defining a chamber and comprising a plurality of elongated chassis frame members extending between either end of the chassis. The chassis houses a compression cylinder that receives a linearly-driven piston that is connected to a voice coil. A power distribution assembly couples current to the voice coil providing oscillating magnetic field and comprises a plurality of electrically conductive linear bearings coupled to a power supply that are configured to facilitate substantially frictionless, bi-directional travel of the piston. One or more permanent magnets mounted to the elongated chassis frame members providing a permanent magnetic field with which the voice coil's oscillating magnetic field interacts.

Abstract: The present invention relates to a canoe that is propelled by a motor. The motor having a shaft and a propeller contained within a hydrodynamically designed housing. The housing further having an inlet and an outlet whereby when the propeller rotates producing thrust, water enters the inlet and is thrust outwardly from the outlet.
