The present invention is a blowout preventer including a large funnel. The large end of the funnel is placed over a well pipe (or other pipe) through which oil (or other fluid) is blowing out. The small end of the funnel is connected to a return pipe. A high pressure pipe with a smaller diameter is inserted into the well pipe. Air is pumped under high pressure through the high pressure pipe, separating the oil and forcing the oil, that is not kept down in the well pipe by the pressure, up through the return pipe. The funnel can be moved into alignment with the well pipe using positioning arms. A stopper may be forced into the well pipe. There are propellers near an end of the high pressure pipe. There are stacked turbines in the return pipe. There is a gasket with pivoting overlapping plates, to seal the pipe.
