Patent ID: 8371888

Claim:
A movable floating object comprising: a floatable body; first and second water pumps mounted on the left and right sides of the body respectively; first and second intake tubes each having an inlet end submerged in water and a pump-connecting end, the pump-connecting ends of the first and second intake tubes being coupled to and in fluid communication with the first and second pumps through first and second intake valves respectively; and first and second discharge tubes each having a discharge end submerged in water and a pump-connecting end, the pump-connecting ends of the first and second discharge tubes being coupled to and in fluid communication with the first and second pumps respectively; wherein exertion of force on the pumps forces water out of the pumps and through the discharge tubes, and release of the force creates a vacuum inside the pumps that sucks water into the pumps through the intake tubes and the intake valves respectively; and wherein the floatable body moves forwards when same force applied to the pumps and turns when the forces applied to the pumps are different; wherein the floatable body is in the shape of a sofa having a seat portion and two armrest portions; and the first and second pumps are located on the two armrest portions respectively.
