ABSTRACT:
A modular, gas-driven power distribution system includes a gasoline-operated module delivering power to a connector having a rotatable element enabling a plurality of mechanical devices to be detachably coupled to the connector to receive power through the rotatable element. The plurality of connectable devices includes a powered oar adapted for nautical purposes. The oar preferably comprises a shaft having a proximal end adapted for detachable coupling to the connector forming part of the gasoline-operated module, and a distal end transitioning into a paddle shape terminating in a rotating prop. A rotatable axle is disposed centrally within the shaft, the axle having a proximal end adapted for detachable coupling to the rotatable element to deliver power to the rotating prop. In addition to the powered oar embodiment, the invention preferably also facilitates interconnection to a reciprocating saw and electrical generator, each having a motive power receiving end adapted for detachable coupling to the rotatable element of the gasoline-operated module.
