ABSTRACT:
This invention is a paddlewheel apparatus having epicyclic gear trains in rotatable holders at opposite ends of a plurality of paddles. The paddles are maintained substantially vertical throughout the rotation of the holders and they are completely unobstructed by any other part of the apparatus in all phases of operation. A housing which extends over the holders and the paddles is open at the bottom to pass the downwardly hanging paddles into the water.
