2. Marine propulsion - Wikipedia

   en.wikipedia.org/wiki/Marine_propulsion

   Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats , most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller , or less frequently, in pump-jets , an ...

   An electric boat is a powered watercraft driven by electric motors, which are powered by either on-board battery packs, solar panels or generators. [ 1 ] While a significant majority of water vessels are powered by diesel engines , with sail power and gasoline engines also popular, boats powered by electricity have been used for over 120 years.

4. Underwater thruster - Wikipedia

   en.wikipedia.org/wiki/Underwater_thruster

   Electric motor: The electric motor is the main component of electric thrusters and drives the propeller. Modern underwater thrusters usually use brush-less permanent magnet synchronous motors . [citation needed] In some low-quality thrusters brushless D.C. motors are used. The gain is lower price and the penalty is lower efficiency.

5. Pump-jet - Wikipedia

   en.wikipedia.org/wiki/Pump-jet

   A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller (axial-flow pump), a centrifugal pump, or a mixed flow pump which is a combination of both centrifugal and axial designs. The design also incorporates an intake to provide water to the pump and ...

6. Water turbine - Wikipedia

   en.wikipedia.org/wiki/Water_turbine

   The main difference between early water turbines and water wheels is a swirl component of the water which passes energy to a spinning rotor. This additional component of motion allowed the turbine to be smaller than a water wheel of the same power. They could process more water by spinning faster and could harness much greater heads.
