A submarine can move faster in water if the water molecules are aligned in the same way. This can be done in several ways. A small device on the front of the ship that sends electrical impulses in the flow of water in respect as the submarine to the area. This device could be separate and divide the water flows through its own way of moving water in the desired direction more like a boat breaking the waves of a water skier. The device could also emit a pulse to align the molecules of water in front of the ship so that water would have less drag and therefore faster.
The water could also be semi-ionized by means of magnets, chemicals, Porcelina magnetic encoders, etc any of those products that streamline moving water through the outer surface submarines stop it. You could even use a wetting agent such as a car wash industry or agricultural uses in amounts only slightly. This technique could be used by the torpedo speed. Navy Seals underwater handheld computers or even the motivation of the hulls of large ships. This saves fuel, increases speed and improves the performance and life of the surface of the vessel. A long pole in front of the submarine could be used or passed through sound waves in front of the unit that you can change the frequency characteristics of the water molecules very slightly and only for a few minutes, at which time re-alignment or interruption of the submarine passing through the area without effort. This same technique could be used inverted as a weapon to stop the boats, underwater unmanned vehicles, interrupt incoming torpedoes (by turning it into an area where the acceleration of the torpedo and then adjust the molecules in the opposite way to stop or pre- ordnance). It could also be used to keep sharks out of the water near the beaches, since they are made of swimming through her that the water department much more difficult.
A submarine could launch small balls of small micro-encapsulated beads of wetting agents Gell ahead of its path if it is a cop material desolve in saltwater as it is dissipated in front of the ship. They can be sent ahead of a vessel by an unmanned craft, crafts, or even flying unmanned underwater UAV unmanned aerial vehicle. These techniques are simply making and testing and testing of this type if they have not been yet to be proven. A submarine could ocated with a magnetic layer to adjust the water molecules crossing the surface due to a charge being manufactured in the coating as the self-cleaning of glass or a small load on the front edge of the submarine, which responsible for the increased resistance that is common in the back of an object that flows through a fluid air or water. There is a problem with ROI deminishing make a submarine, more streamlined, lighter, better materials, smoother surfaces, as we have done all this and wrestled with the issues to develop the largest submarines in the world has ever known, is not it time we started working on the other component After all it is the sub, the propulsion system and water. Once you have created the best in others, it’s time to realign the chaos of the water molecules to improve their efforts. God does not care, I could even imagine the idea soon.
