I figured out how to modify (weaken) a Hurricane and prevent tornados with a pipeline while using the rotational velocity of the Earth. Actually, the Earth is a Giant Pump.Gravity is greater at the poles of the Earth because the Earth is not spinning with as much velocity. This why you would weigh more at the poles. At the Equator the Earth is rotating at near >1000kmphr. If you were to run a pipeline with both openings at the same elevation at each location water would flow from the pole to the equator.If we can build a pipeline from the artic ocean to the Fl keys it would be possible to pump very cold water using the Earth as a pump. No electricity needed. Open a valve near the end and cold water would flow and mix into the gulfstream near keys thus weakening hurricanes and perhaps preventing tornados if cool water is sent to the Gulf Of Mexico,also. Can you Calculate the exit velocity of the water from the pipeline at the Equater and don't forget the angular velocity? "Earth The Giant Pump" PS Think of the electricity it can make???
