Abstract: In one possible implementation the invention is electrical generating system, having: a wind power assembly having at least two rotatable propulsion systems: said wind power assembly further having an air pump, the air pump being connected to the wind power assembly and creating an air flow when rotatable propulsion systems rotate in response to wind; and an air powered generator connected to the wind power assembly, the air powered generator capable of creating electrical current as a result of the air flow from the wind power assembly.

Abstract: The present invention is a device to be used in emergency situations requiring floatation and rescue. An inflatable raft with a waterproof cover is connected to a telescopic shaft equipped with electric generators and wind catchers. The electricity, which is produced powers a motor and propeller underneath and outside the raft.

Abstract: A method of manufacturing a pump impeller and a pump impeller which is constructed primarily in a single molding operation. The pump impeller has a shroud which includes an inlet opening located on one side of a series of vanes. On the opposite side of the series of vanes is a hub and from the hub extends a shaft sleeve. The axis of rotation of the shaft sleeve aligns with the longitudinal center axis of the inlet opening.
