Abstract
A human powered mechanism for propelling a wheeled land vehicle, a water vehicle (a boat or hydroplane) using either a water screw or a jet of water or an ultra-light aircraft with an air screw. The mechanism can utilize either arm or leg muscles or preferably, both arms and legs extending and retracting in a manner similar to walking or running as performed from a semi-recumbent position. Steering or other critical control is accomplished through another mechanism which is guided by the appropriate movement of the operator's head. The operators feet are placed on pedals which are attached to swinging members which pivot in a bearing at the upper end. The operator's hands grasp leverage arms which are cantilevered, the distal ends of which are attached to the same push-pull connecting rods as the above mentioned swinging members with foot pedals attached.
