Stopping the oil spill with the Bernoulli's Principle

Since President Obama has never talked with the CEO of BP, and BP have been in charge of stopping the oil spill,things have continue to go from bad to worse, and there have been several great ideas from people not connected with the oil industry, and from some in the fuel section of the military to stop the flow of oil from the Gulf Of Mexico.The only major problem with stopping the spill with conventional methods or ideas by these individuals is the lack of knowledge of the rate of flow of the oil, the pressure from the oil well, pressure of water of the Gulf at the site of the well. Now, there is the Batching pig, which is common knowledge in the oil and fuel industry, and some one from Minnesota just came up with the idea of a hydraulic cap to stop the oil flow, and or control the oil flow to the ship above the spill to capture and refine the oil with with a fuel oil spectator, thus keeping the profit of BP growing.The hydraulic cap again is not a new idea, it is a modification and use of the Bernoulli's Principle, which again is not new to those in fuel and hydraulics....What is the Bernoulli's Principle? As a person who worked as a liquid fuel technician in the military, this is a simple definition of the Bernoulli's Principle: In Fluid dynamics , Bernoulli's principle states that for an Inviscid flow of the fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy. Bernoulli's principle is named after the Dutch-Swiss mathematician Daniel Bernoulli who published his principle in his book Hydrodynamica in 1738. Bernoulli's principle can be applied to various types of fluid flow, resulting in what is loosely denoted as Bernoulli's equation. Fluid particles are subject only to pressure and their own weight. If a fluid is flowing horizontally and along a section of a streamline, where the speed increases it can only be because the fluid on that section has moved from a region of higher pressure to a region of lower pressure; and if its speed decreases, it can only be because it has moved from a region of lower pressure to a region of higher pressure. Consequently, within a fluid flowing horizontally, the highest speed occurs where the pressure is lowest, and the lowest speed occurs where the pressure is highest.In most flows of liquids, and of gases at low Mach number, the mass density of a fluid parcel can be considered to be constant, regardless of pressure variations in the flow. For this reason the fluid in such flows can be considered to be incompressible and these flows can be described as incompressible flow. Bernoulli performed his experiments on liquids and his equation in its original form is valid only for incompressible flow. A common form of Bernoulli's equation, valid at any arbitrary point along a streamline where gravity is constant.
