ABSTRACT:
A paddle wheel for propelling a water craft. The paddle wheel includes a plurality of oppositely disposed paddles which are rotatable with a supporting shaft.

The bottom half portion of the paddles is filled with concrete and the upper half is filled with air or evacuated. Thus, the paddles remain in a vertical position as the paddle wheel rotates.
