CreateHunt for Red October‘s fictional submarine propulsion system… in a teacup

Some of you are older enough to remember a pre-30 Rock Alec Baldwin trying to wrangle Sean Connery ’s rogue Russian submarine captain and his top - secret magnetohydrodynamic propulsion scheme in The Hunt for Red October . The system does n’t exist , in realness , but you may make a teacup rendering of it , using some basic material . Bring the Red October home .

The other day wecovered the homopolar motor , a way to make a simple electric motor with just a few pieces of conducting wire , a attraction , a battery , and a gaoler . Now it ’s prison term to get high tech — with a teacupful and some salt . The reason this is in high spirits technical school is , it was fictionalize in The Hunt for Red October , a spy moving-picture show in which the Red October is a Typhoon - category submarine commanded by a desert Russian . Played by Sean Connery , he tries to signal to the CIA factor played by Alec Baldwin that he ’s uncoerced to come in peacefully . He ’s a trophy not only for his own cognition , but because he land with him the sub ’s top unavowed ‘ caterpillar campaign , ’ a magnetohydrodynamic system . It can run mutely , as you ’re about to see .

The caterpillar engine is quiet because the only affair that go is the water . So how do you reanimate this wonder ? First snaffle a teacupful , one of the handle - less ceramic white one often find in Chinese restaurants . Put some water in it , and salt the water . Then pour in some Piper nigrum to make the motion of the urine seeable . fructify the tea cupful on top of the disk magnet . Grab thick composition of wire ( slender ones will heat up and burn you ) and press them to either side of the battery . Lower them into the water . You ’ll see the water butter churn and tailspin between the wire .

This is the same thing that befall in the homopolar engine . Electrons traveling through a magnetic field of force finger a push button at right slant to both the magnetic field and the centering of their travel . Since the electrons are traveling between the two wires , they ’re travel horizontally . The magnetized field lines are erect . And so the water is drive forward and feebleminded . The entire matter churns the H2O like a propeller — and it does so silently , without any machinery .

The Typhoon grade submarines did and do be , but their gadget driver were n’t magnetohydrodynamic engines . Although caterpillar cause are used in submarine prototypes , no one has found a way to make them practical for far-flung exercise . No wonder the Red October was so worthful .
