2. Voith Schneider Propeller - Wikipedia

   en.wikipedia.org/wiki/Voith_Schneider_Propeller

   Voith Schneider Propeller. The Voith Schneider Propeller (VSP) is a specialized marine propulsion system (MPS) manufactured by the Voith Group based on a cyclorotor design. It is highly maneuverable, being able to change the direction of its thrust almost instantaneously. It is widely used on tugs and ferries.

3. Rim-driven thruster - Wikipedia

   en.wikipedia.org/wiki/Rim-driven_thruster

   Rim–driven thruster, presented at SMM 2010. Th e rim-driven thruster, also known as rim-driven propulsor/propeller (or RDP) is a novel type of electric propulsion unit for ships. The concept was proposed by Kort around 1940, but only became commercially practical in the early 21st century due to advances in DC motor controller technology. [1]

4. Electric boat - Wikipedia

   Marine propulsion. Rolls-Royce Marine Spey, a gas turbine developed by Rolls-Royce Holdings in the 1960s for 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 ...

7. Magnetohydrodynamic drive - Wikipedia

   en.wikipedia.org/wiki/Magnetohydrodynamic_drive

   The first working full-scale MHD ship. A magnetohydrodynamic drive or MHD accelerator is a method for propelling vehicles using only electric and magnetic fields with no moving parts, accelerating an electrically conductive propellant (liquid or gas) with magnetohydrodynamics. The fluid is directed to the rear and as a reaction, the vehicle ...
