Electric light and toasters run on electricity "generated" by the generator.
A lot of ships have electric engines. On cruise ships, diesel electric propulsion offers quieter and smoother rides. Some air-craft carriers and submarines have nuclear-electric propulsion systems.
The article made me cringe, too, but mainly because it created a false impression on how big magnets are really energized. I've done it a few times (always with the same magnet, which keeps quenching...), and described the process here:

- extrapickles 11y agoDiesel electric propulsion is quietly taking over most large mobile applications. Even cars are slowly going gasoline-electric. Better magnetics would only speed up the switch. Of ships it has what you stated, and you no longer have to build the engine on a incline to drive the propeller or have complex transmissions. Other benefits are you can have 2 engines and only run 1 during calm weather cruse. Also electric motors are able to be mounted in stearable pods, greatly increasing maneuverability of a ship (need fewer tugs to go into port). Some ships have nothing but the pods for good station keeping. Multiple locomotive trains only need 1 engine, but run power to several for extra traction, and it enables things like traction control that can't be cheaply done mechanically.
