Abstract: A flying outboard boat which can fly over the water having only its propeller rotates in the water comprises a hull with wings project on both sides. Underneath the wings there installed flaps one couple at anterior part and another couple at posterior part of said boat to help lifting and tilting of said boat by moving the flaps pivotally up or down. The engine of the boat can move vertically through moving a frame the engine mounted to by a motor where the propeller installed to the lowest end of a stem of the engine. Navigation control systems comprises a steering wheel, an accelerating pedal, switches to move the engine up and down by a motor, switches to move flaps and lastly, electrical and electronics circuits to control switches and motors.

Abstract: A machine for cleaning outer wall of a high-rise building pushed by a rotating propeller which is at the back of the machine outside a case having rotating brushes chambers, driven by an engine or a motor to press against a wall to be cleaned comprises: a case divided into chambers having an opened-anterior side where edges of all the chambers having rubber plates or brushes mounted all along their rims. In each chamber, there is a rotating brush (or brushes) for scrubbing where detergent solution or water may be ejected onto the rotating brush. At the back of each chamber there is a tube for draining used liquid away or keeping in a reservoir of the machine. There are steel plates mounted vertically one to the top and one to the bottom of the case, where a rubber plate is mounted horizontally along the top steel plate to help wiping off liquid film left on the surface of the wall.

Abstract: A machine for cleaning the outer wall of a high-rise building using a pneumatic system or a vacuum system consists of a case divided into three chambers vertically arranged having an opened-anterior side where edges of all chambers having rubber plates or brushes mounted all along their rims. In each upper and lower chamber there is mounted a roller having its surface aligned with an edge of the rubber plates or brushes. The machine is pressed against a wall to be cleaned be either a pneumatic or vacuum mechanism. The machine moves along a wall which cleaning by shifting a cable tied at the top of a case. In a middle chamber, there is a drum-brush whose hair sticks out over the level of the edge of the rubber plate or brushes. There is also tubing to eject water and/or detergent solution to the drum-brush, and where the drum-brush is motor-driven in cleaning the wall.
